Example

<!DOCTYPE html>
<html>
<body>

<h1>My First Heading</h1>

<p>My first paragraph.</p>

</body>
</html>

Example Explained

The DOCTYPE declaration defines the document type
The text between <html> and </html> describes the web page
The text between <body> and </body> is the visible page content
The text between <h1> and </h1> is displayed as a heading
The text between <p> and </p> is displayed as a paragraph

What is HTML?

HTML is a language for describing web pages.

HTML stands for Hyper Text Markup Language
HTML is not a programming language, it is a markup language
A markup language is a set of markup tags
The purpose of the tags are to describe page content

HTML Tags

HTML markup tags are usually called HTML tags

HTML tags are keywords (tag names) surrounded by angle brackets like <html>
HTML tags normally come in pairs like <b> and </b>
The first tag in a pair is the start tag, the second tag is the end tag
The end tag is written like the start tag, with a forward slash before the tag name
Start and end tags are also called opening tags and closing tags

<tagname>content</tagname>

HTML Elements

"HTML tags" and "HTML elements" are often used to describe the same thing.

But strictly speaking, an HTML element is everything between the start tag and the end tag, including the tags:

HTML Element:

<p>This is a paragraph.</p>

HTML Documents = Web Pages

HTML documents describe web pages
HTML documents contain HTML tags and plain text
HTML documents are also called web pages

Web Browsers

The purpose of a web browser (Chrome, Internet Explorer, Firefox) is to read HTML documents and display them as web pages. The browser does not display the HTML tags, but uses the tags to interpret the content of the page:

HTML Page Structure

Below is a visualization of an HTML page structure:

<html>

<body>

<h1>This a Heading</h1>

<p>This is a paragraph.</p>

<p>This is another paragraph.</p>

</body>

</html>

HTML Headings

HTML headings are defined with the <h1> to <h6> tags.

Example

<h1>This is a heading</h1>
<h2>This is a heading</h2>
<h3>This is a heading</h3>

HTML Paragraphs

HTML paragraphs are defined with the <p> tag.

Example

<p>This is a paragraph.</p>
<p>This is another paragraph.</p>

HTML Links

HTML links are defined with the <a> tag.

Example

Note: The link address is specified in the href attribute.

(You will learn about attributes in a later chapter of this tutorial).

HTML Images

HTML images are defined with the <img> tag.

Example

Note: The filename and the size of the image are provided as attributes.

HTML documents are defined by HTML elements.

HTML Elements

An HTML element is everything from the start tag to the end tag:

Start tag *	Element content	End tag *
<p>	This is a paragraph	</p>
<a href="default.htm">	This is a link	</a>
<br />

* The start tag is often called the opening tag. The end tag is often called the closing tag.

HTML Element Syntax

An HTML element starts with a start tag / opening tag
An HTML element ends with an end tag / closing tag
The element content is everything between the start and the end tag
Some HTML elements have empty content
Empty elements are closed in the start tag
Most HTML elements can have attributes

Tip: You will learn about attributes in the next chapter of this tutorial.

Nested HTML Elements

Most HTML elements can be nested (can contain other HTML elements).

HTML documents consist of nested HTML elements.

HTML Document Example

<!DOCTYPE html>
<html>

<body>
<p>This is my first paragraph.</p>
</body>

</html>

The example above contains 3 HTML elements.

HTML Example Explained

The <p> element:

<p>This is my first paragraph.</p>

The <p> element defines a paragraph in the HTML document.
The element has a start tag <p> and an end tag </p>.
The element content is: This is my first paragraph.

The <body> element:

<body>
<p>This is my first paragraph.</p>
</body>

The <body> element defines the body of the HTML document.
The element has a start tag <body> and an end tag </body>.
The element content is another HTML element (a p element).

The <html> element:

<html>

<body>
<p>This is my first paragraph.</p>
</body>

</html>

The <html> element defines the whole HTML document.
The element has a start tag <html> and an end tag </html>.
The element content is another HTML element (the body element).

Don't Forget the End Tag

Some HTML elements might display correctly even if you forget the end tag:

<p>This is a paragraph
<p>This is a paragraph

The example above works in most browsers, because the closing tag is considered optional.

Never rely on this. Many HTML elements will produce unexpected results and/or errors if you forget the end tag .

Empty HTML Elements

HTML elements with no content are called empty elements.

<br> is an empty element without a closing tag (the <br> tag defines a line break).

Tip: In XHTML, all elements must be closed. Adding a slash inside the start tag, like <br />, is the proper way of closing empty elements in XHTML (and XML).

HTML Tip: Use Lowercase Tags

HTML tags are not case sensitive: <P> means the same as <p>. Many web sites use uppercase HTML tags.

W3Schools use lowercase tags because the World Wide Web Consortium (W3C) recommends lowercase in HTML 4, and demands lowercase tags in XHTML.

Attributes provide additional information about HTML elements.

HTML Attributes

HTML elements can have attributes
Attributes provide additional information about an element
Attributes are always specified in the start tag
Attributes come in name/value pairs like: name="value"

Attribute Example

HTML links are defined with the <a> tag. The link address is specified in the href attribute:

Example

Always Quote Attribute Values

Attribute values should always be enclosed in quotes.

Double style quotes are the most common, but single style quotes are also allowed.

HTML Tip: Use Lowercase Attributes

Attribute names and attribute values are case-insensitive.

However, the World Wide Web Consortium (W3C) recommends lowercase attributes/attribute values in their HTML 4 recommendation.

Newer versions of (X)HTML will demand lowercase attributes.

HTML Attributes Reference

Below is a list of some attributes that are standard for most HTML elements:

Attribute	Value	Description
class	Classname	Specifies a classname for an element
id	Id	Specifies a unique id for an element
style	style_definition	Specifies an inline style for an element
title	tooltip_text	Specifies extra information about an element (displayed as a tool tip)

HTML Headings

Headings are defined with the <h1> to <h6> tags.

<h1> defines the most important heading. <h6> defines the least important heading.

Example

<h1>This is a heading</h1>
<h2>This is a heading</h2>
<h3>This is a heading</h3>

Note: Browsers automatically add some empty space (a margin) before and after each heading.

Headings Are Important

Use HTML headings for headings only. Don't use headings to make text BIG or bold.

Search engines use your headings to index the structure and content of your web pages.

Since users may skim your pages by its headings, it is important to use headings to show the document structure.

H1 headings should be used as main headings, followed by H2 headings, then the less important H3 headings, and so on.

HTML Lines

The <hr /> tag creates a horizontal line in an HTML page.

The hr element can be used to separate content:

Example

<p>This is a paragraph</p>
<hr />
<p>This is a paragraph</p>
<hr />
<p>This is a paragraph</p>

Try it yourself »

HTML Comments

Comments can be inserted into the HTML code to make it more readable and understandable. Comments are ignored by the browser and are not displayed.

Comments are written like this:

Example

Try it yourself »

Note: There is an exclamation point after the opening bracket, but not before the closing bracket.

HTML Tip - How to View HTML Source

Have you ever seen a Web page and wondered "Hey! How did they do that?"

To find out, right-click in the page and select "View Source" (IE) or "View Page Source" (Firefox), or similar for other browsers. This will open a window containing the HTML code of the page.

HTML Tag Reference

W3Schools' tag reference contains additional information about these tags and their attributes.

You will learn more about HTML tags and attributes in the next chapters of this tutorial.

Tag	Description
<html>	Defines an HTML document
<body>	Defines the document's body
<h1> to <h6>	Defines HTML headings
<hr />	Defines a horizontal line
<!-->	Defines a comment

HTML documents are divided into paragraphs.

HTML Paragraphs

Paragraphs are defined with the <p> tag.

Example

<p>This is a paragraph</p>
<p>This is another paragraph</p>

Note: Browsers automatically add an empty line before and after a paragraph.

Don't Forget the End Tag

Most browsers will display HTML correctly even if you forget the end tag:

Example

<p>This is a paragraph
<p>This is another paragraph

The example above will work in most browsers, but don't rely on it. Forgetting the end tag can produce unexpected results or errors.

Note: Future version of HTML will not allow you to skip end tags.

HTML Line Breaks

Use the <br /> tag if you want a line break (a new line) without starting a new paragraph:

Example

<p>This is<br />a para<br />graph with line breaks</p>

The <br /> element is an empty HTML element. It has no end tag.

<br> or <br />

In XHTML, XML, elements with no end tag (closing tag) are not allowed.

Even if <br> works in all browsers, writing <br /> instead works better in XHTML and XML applications.

HTML Output - Useful Tips

You cannot be sure how HTML will be displayed. Large or small screens, and resized windows will create different results.

With HTML, you cannot change the output by adding extra spaces or extra lines in your HTML code.

The browser will remove extra spaces and extra lines when the page is displayed. Any number of lines count as one line, and any number of spaces count as one space.

HTML Tag Reference

W3Schools' tag reference contains additional information about HTML elements and their attributes.

Tag	Description
<p>	Defines a paragraph
<br />	Inserts a single line break

HTML Text Formatting

This text is bold

This text is big

This text is italic

This is computer output

This is_subscript and ^superscript

HTML Formatting Tags

HTML uses tags like <b> and <i> for formatting output, like bold or italic text.

These HTML tags are called formatting tags (look at the bottom of this page for a complete reference).

Often <strong> renders as <b>, and <em> renders as <i>.

However, there is a difference in the meaning of these tags:

<b> or <i> defines bold or italic text only.

<strong> or <em> means that you want the text to be rendered in a way that the user understands as "important". Today, all major browsers render strong as bold and em as italics. However, if a browser one day wants to make a text highlighted with the strong feature, it might be cursive for example and not bold!

HTML Text Formatting Tags

Tag	Description
<b>	Defines bold text
<big>	Defines big text
<em>	Defines emphasized text
<i>	Defines italic text
<small>	Defines small text
<strong>	Defines strong text
<sub>	Defines subscripted text
<sup>	Defines superscripted text
<ins>	Defines inserted text
<del>	Defines deleted text

HTML "Computer Output" Tags

Tag	Description
<code>	Defines computer code text
<kbd>	Defines keyboard text
<samp>	Defines sample computer code
<tt>	Defines teletype text
<var>	Defines a variable
<pre>	Defines preformatted text

HTML Citations, Quotations, and Definition Tags

Tag	Description
<abbr>	Defines an abbreviation
<acronym>	Defines an acronym
<address>	Defines contact information for the author/owner of a document
<bdo>	Defines the text direction
<blockquote>	Defines a long quotation
<q>	Defines a short quotation
<cite>	Defines a citation
<dfn>	Defines a definition term

Writing HTML Using Notepad or TextEdit

HTML can be edited by using a professional HTML editor like:

Adobe Dreamweaver
Microsoft Expression Web
CoffeeCup HTML Editor

However, for learning HTML we recommend a text editor like Notepad (PC) or TextEdit (Mac). We believe using a simple text editor is a good way to learn HTML.

Follow the 4 steps below to create your first web page with Notepad.

Step 1: Start Notepad

To start Notepad go to:

Start
    All Programs
        Accessories
            Notepad

Step 2: Edit Your HTML with Notepad

Type your HTML code into your Notepad:

Step 3: Save Your HTML

Select Save as.. in Notepad's file menu.

When you save an HTML file, you can use either the .htm or the .html file extension. There is no difference, it is entirely up to you.

Save the file in a folder that is easy to remember, like w3schools.

Step 4: Run the HTML in Your Browser

Start your web browser and open your html file from the File, Open menu, or just browse the folder and double-click your HTML file.

The result should look much like this:

CSS (Cascading Style Sheets) is used to style HTML elements.

Look! Styles and colors

This text is in Verdana and red
This text is in Times and blue
This text is 30 pixels high

Styling HTML with CSS

CSS was introduced together with HTML 4, to provide a better way to style HTML elements.
CSS can be added to HTML in the following ways:

Inline - using the style attribute in HTML elements
Internal - using the <style> element in the <head> section
External - using an external CSS file

The preferred way to add CSS to HTML, is to put CSS syntax in separate CSS files.
However, in this HTML tutorial we will introduce you to CSS using the style attribute. This i

s done to simplify the examples. It also makes it easier for you to edit the code and try it yourself.

Inline Styles

An inline style can be used if a unique style is to be applied to one single occurrence of an element.
To use inline styles, use the style attribute in the relevant tag. The style attribute can contain any CSS property. The example below shows how to change the text color and the left margin of a paragraph:

<p style="color:blue;margin-left:20px;">This is a paragraph.</p>

HTML Style Example - Background Color

The background-color property defines the background color for an element:

Example

<!DOCTYPE html>
<html>

<body style="background-color:yellow;">
<h2 style="background-color:red;">This is a heading</h2>
<p style="background-color:green;">This is a paragraph.</p>
</body>

</html>

HTML Style Example - Font, Color and Size

The font-family, color, and font-size properties defines the font, color, and size of the text in an element:

Example

<!DOCTYPE html>
<html>

<body>
<h1 style="font-family:verdana;">A heading</h1>
<p style="font-family:arial;color:red;font-size:20px;">A paragraph.</p>
</body>

</html>

HTML Style Example - Text Alignment

The text-align property specifies the horizontal alignment of text in an element:

Example

<!DOCTYPE html>
<html>

<body>
<h1 style="text-align:center;">Center-aligned heading</h1>
<p>This is a paragraph.</p>
</body>

</html>

Internal Style Sheet

An internal style sheet can be used if one single document has a unique style. Internal styles are defined in the <head> section of an HTML page, by using the <style> tag, like this:

<head>
<style type="text/css">
body {background-color:yellow;}
p {color:blue;}
</style>
</head>

External Style Sheet

An external style sheet is ideal when the style is applied to many pages. With an external style sheet, you can change the look of an entire Web site by changing one file. Each page must link to the style sheet using the <link> tag. The <link> tag goes inside the <head> section:

HTML Style Tags

Tag	Description
<style>	Defines style information for a document
<link />	Defines the relationship between a document and an external resource

Deprecated Tags and Attributes

In HTML 4, several tags and attributes were used to style documents. These tags are not supported in newer versions of HTML.
Avoid using the elements <font>, <center>, and <strike> and the attributes color and bgcolor.

Links are found in nearly all Web pages. Links allow users to click their way from page to page.

HTML Hyperlinks (Links)

A hyperlink (or link) is a word, group of words, or image that you can click on to jump to a new document or a new section within the current document.

When you move the cursor over a link in a Web page, the arrow will turn into a little hand.

Links are specified in HTML using the <a> tag.

The <a> tag can be used in two ways:

1. To create a link to another document, by using the href attribute

2. To create a bookmark inside a document, by using the name attribute

HTML Link Syntax

The HTML code for a link is simple. It looks like this:

The href attribute specifies the destination of a link.

Example

<a href="http://www.w3schools.com/">Visit W3Schools</a>

which will display like this: Visit W3Schools

Clicking on this hyperlink will send the user to W3Schools' homepage.

Tip: The "Link text" doesn't have to be text. It can be an image or any other HTML element.

HTML Links - The target Attribute

The target attribute specifies where to open the linked document.

The example below will open the linked document in a new browser window or a new tab:

Example

<a href="http://www.w3schools.com/" target="_blank">Visit W3Schools!</a>

HTML Links - The name Attribute

The name attribute specifies the name of an anchor.

The name attribute is used to create a bookmark inside an HTML document.

Note: The upcoming HTML5 standard suggests using the id attribute instead of the name attribute for specifying the name of an anchor. Using the id attribute actually works also for HTML4 in all modern browsers.

Bookmarks are not displayed in any special way. They are invisible to the reader.

Example

A named anchor inside an HTML document:

<a name="tips">Useful Tips Section</a>

Create a link to the "Useful Tips Section" inside the same document:

<a href="#tips">Visit the Useful Tips Section</a>

Or, create a link to the "Useful Tips Section" from another page:

<a href="http://www.w3schools.com/html_links.htm#tips">
Visit the Useful Tips Section</a>

Basic Notes - Useful Tips

Note: Always add a trailing slash to subfolder references. If you link like this: href="http://www.w3schools.com/html", you will generate two requests to the server, the server will first add a slash to the address, and then create a new request like this: href="http://www.w3schools.com/html/".

Tip: Named anchors are often used to create "table of contents" at the beginning of a large document. Each chapter within the document is given a named anchor, and links to each of these anchors are put at the top of the document.

HTML Link Tags

Tag	Description
<a>	Defines an anchor

Example

Norwegian Mountain Trip

HTML Images - The <img> Tag and the Src Attribute

In HTML, images are defined with the <img> tag.

The <img> tag is empty, which means that it contains attributes only, and has no closing tag.

To display an image on a page, you need to use the src attribute. Src stands for "source". The value of the src attribute is the URL of the image you want to display.

Syntax for defining an image:

The URL points to the location where the image is stored. An image named "boat.gif", located in the "images" directory on "www.w3schools.com" has the URL: http://www.w3schools.com/images/boat.gif.

The browser displays the image where the <img> tag occurs in the document. If you put an image tag between two paragraphs, the browser shows the first paragraph, then the image, and then the second paragraph.

HTML Images - The Alt Attribute

The required alt attribute specifies an alternate text for an image, if the image cannot be displayed.

The value of the alt attribute is an author-defined text:

The alt attribute provides alternative information for an image if a user for some reason cannot view it (because of slow connection, an error in the src attribute, or if the user uses a screen reader).

HTML Images - Set Height and Width of an Image

The height and width attributes are used to specify the height and width of an image.

The attribute values are specified in pixels by default:

Tip: It is a good practice to specify both the height and width attributes for an image. If these attributes are set, the space required for the image is reserved when the page is loaded. However, without these attributes, the browser does not know the size of the image. The effect will be that the page layout will change during loading (while the images load).

Basic Notes - Useful Tips

Note: If an HTML file contains ten images - eleven files are required to display the page right. Loading images takes time, so my best advice is: Use images carefully.

Note: When a web page is loaded, it is the browser, at that moment, that actually gets the image from a web server and inserts it into the page. Therefore, make sure that the images actually stay in the same spot in relation to the web page, otherwise your visitors will get a broken link icon. The broken link icon is shown if the browser cannot find the image.

HTML Image Tags

Tag	Description
<img />	Defines an image
<map>	Defines an image-map
<area />	Defines a clickable area inside an image-map

HTML Tables

Apples	44%
Bananas	23%
Oranges	13%
Other	10%

HTML Tables

Tables are defined with the <table> tag.

A table is divided into rows (with the <tr> tag), and each row is divided into data cells (with the <td> tag). td stands for "table data," and holds the content of a data cell. A <td> tag can contain text, links, images, lists, forms, other tables, etc.

Table Example

How the HTML code above looks in a browser:

row 1, cell 1	row 1, cell 2
row 2, cell 1	row 2, cell 2

HTML Tables and the Border Attribute

If you do not specify a border attribute, the table will be displayed without borders. Sometimes this can be useful, but most of the time, we want the borders to show.

To display a table with borders, specify the border attribute:

HTML Table Headers

Header information in a table are defined with the <th> tag.

All major browsers display the text in the <th> element as bold and centered.

<table border="1">
<tr>
<th>Header 1</th>
<th>Header 2</th>
</tr>
<tr>
<td>row 1, cell 1</td>
<td>row 1, cell 2</td>
</tr>
<tr>
<td>row 2, cell 1</td>
<td>row 2, cell 2</td>
</tr>
</table>

How the HTML code above looks in your browser:

Header 1	Header 2
row 1, cell 1	row 1, cell 2
row 2, cell 1	row 2, cell 2

HTML Table Tags

Tag	Description
<table>	Defines a table
<th>	Defines a table header
<tr>	Defines a table row
<td>	Defines a table cell
<caption>	Defines a table caption
<colgroup>	Defines a group of columns in a table, for formatting
<col />	Defines attribute values for one or more columns in a table
<thead>	Groups the header content in a table
<tbody>	Groups the body content in a table
<tfoot>	Groups the footer content in a table

HTML Lists

An ordered list:

1. The first list item

2. The second list item

3. The third list item

An unordered list:

List item
List item
List item

HTML Unordered Lists

An unordered list starts with the <ul> tag. Each list item starts with the <li> tag.
The list items are marked with bullets (typically small black circles).

<ul>
<li>Coffee</li>
<li>Milk</li>
</ul>

How the HTML code above looks in a browser:

Coffee
Milk

HTML Ordered Lists

An ordered list starts with the <ol> tag. Each list item starts with the <li> tag.
The list items are marked with numbers.

<ol>
<li>Coffee</li>
<li>Milk</li>
</ol>

How the HTML code above looks in a browser:

1. Coffee

2. Milk

HTML Definition Lists

A definition list is a list of items, with a description of each item.
The <dl> tag defines a definition list.
The <dl> tag is used in conjunction with <dt> (defines the item in the list) and <dd> (describes the item in the list):

<dl>
<dt>Coffee</dt>
<dd>- black hot drink</dd>
<dt>Milk</dt>
<dd>- white cold drink</dd>
</dl>

How the HTML code above looks in a browser:

Coffee

- black hot drink

Milk

- white cold drink

Basic Notes - Useful Tips

Tip: Inside a list item you can put text, line breaks, images, links, other lists, etc.

HTML List Tags

Tag	Description
<ol>	Defines an ordered list
<ul>	Defines an unordered list
<li>	Defines a list item
<dl>	Defines a definition list
<dt>	Defines an item in a definition list
<dd>	Defines a description of an item in a definition list

HTML elements can be grouped together with <div> and <span>

HTML Block Elements

Most HTML elements are defined as block level elements or as inline elements.

Block level elements normally start (and end) with a new line when displayed in a browser.

Examples: <h1>, <p>, <ul>, <table>

HTML Inline Elements

Inline elements are normally displayed without starting a new line.

Examples: <b>, <td>, <a>, <img>

The HTML <div> Element

The HTML <div> element is a block level element that can be used as a container for grouping other HTML elements.

The <div> element has no special meaning. Except that, because it is a block level element, the browser will display a line break before and after it.

When used together with CSS, the <div> element can be used to set style attributes to large blocks of content.

Another common use of the <div> element, is for document layout. It replaces the "old way" of defining layout using tables. Using tables is not the correct use of the <table> element. The purpose of the <table> element is to display tabular data.

The HTML <span> Element

The HTML <span> element is an inline element that can be used as a container for text.

The <span> element has no special meaning.

When used together with CSS, the <span> element can be used to set style attributes to parts of the text.

Web page layout is very important to make your website look good.

Design your webpage layout very carefully.

<table> elements.

Website Layouts

Most websites have put their content in multiple columns (formatted like a magazine or newspaper).
Multiple columns are created by using <div> or <table> elements. CSS are used to position elements, or to create backgrounds or colorful look for the pages.

HTML Layouts - Using <div> Elements

The div element is a block level element used for grouping HTML elements.
The following example uses five div elements to create a multiple column layout, creating the same result as in the previous example:

Example

<!DOCTYPE html>
<html>
<body>

<div id="container" style="width:500px">

<div id="header" style="background-color:#FFA500;">
<h1 style="margin-bottom:0;">Main Title of Web Page</h1></div>

<div id="menu" style="background-color:#FFD700;height:200px;width:100px;float:left;">
<b>Menu</b><br />
HTML<br />
CSS<br />
JavaScript</div>

<div id="content" style="background-color:#EEEEEE;height:200px;width:400px;float:left;">
Content goes here</div>

<div id="footer" style="background-color:#FFA500;clear:both;text-align:center;">
Copyright © W3Schools.com</div>

</div>

</body>
</html>

The HTML code above will produce the following result:

Main Title of Web Page

Menu
HTML
CSS
JavaScript

Content goes here

HTML Layouts - Using Tables

A simple way of creating layouts is by using the HTML <table> tag.
Multiple columns are created by using <div> or <table> elements. CSS are used to position elements, or to create backgrounds or colorful look for the pages.

Using tables is not the correct use of the <table> element. The purpose of the <table> element is to display tabular data.

The following example uses a table with 3 rows and 2 columns - the first and last row spans both columns using the colspan attribute:

Example

<!DOCTYPE html>
<html>
<body>

<table width="500" border="0">
<tr>
<td colspan="2" style="background-color:#FFA500;">
<h1>Main Title of Web Page</h1>
</td>
</tr>

<tr valign="top">
<td style="background-color:#FFD700;width:100px;text-align:top;">
<b>Menu</b><br />
HTML<br />
CSS<br />
JavaScript
</td>
<td style="background-color:#EEEEEE;height:200px;width:400px;text-align:top;">
Content goes here</td>
</tr>

<tr>
<td colspan="2" style="background-color:#FFA500;text-align:center;">
Copyright © W3Schools.com</td>
</tr>
</table>

</body>
</html>

The HTML code above will produce the following result:

Main Title of Web Page
Menu HTML CSS JavaScript	Content goes here
Copyright © W3Schools.com

HTML Layout - Useful Tips

Tip: The biggest advantage of using CSS is that, if you place the CSS code in an external style sheet, your site becomes MUCH EASIER to maintain. You can change the layout of all your pages by editing one file. To learn more about CSS, study our CSS tutorial.
Tip: Because advanced layouts take time to create, a quicker option is to use a template. Search Google for free website templates (these are pre-built website layouts you can use and customize).

HTML Layout Tags

Tag	Description
<div>	Defines a section in a document
<span>	Defines a section in a document

HTML Forms are used to select different kinds of user input.

HTML Forms

HTML forms are used to pass data to a server.

A form can contain input elements like text fields, checkboxes, radio-buttons, submit buttons and more. A form can also contain select lists, textarea, fieldset, legend, and label elements.

The <form> tag is used to create an HTML form:

<form>
.
input elements
.
</form>

HTML Forms - The Input Element

The most important form element is the input element.

The input element is used to select user information.

An input element can vary in many ways, depending on the type attribute. An input element can be of type text field, checkbox, password, radio button, submit button, and more.

The most used input types are described below.

Text Fields

<input type="text" /> defines a one-line input field that a user can enter text into:

<form>
First name: <input type="text" name="firstname" /><br />
Last name: <input type="text" name="lastname" />
