HTML <div> Tag

The HTML <div> tag represents a generic section within an HTML document. The <div> tag enables you to group sections of HTML elements together and format them with CSS.

The <div> element is similar to the <span> element, however the <span> element is used with inline elements, whereas the <div> element is used with block-level elements.

The <div> element accepts "flow content", which refers to most elements that can appear inside a document's body.

The <div> should only be used as a last resort when there isn't another suitable HTML element to use. HTML5 has introduced a number of new elements that can (and should) be used in place of the <div>. These include <article>, <aside>, <header>, and <footer> and others. See below under "Differences Between HTML 4 & HTML 5" for more information on this.

Syntax

The <div> tag is written as <div></div> with the generic content inserted between the start and end tags.

Like this:

<div> Generic content here... </div>

Examples

Basic tag usage

As you can see, simply placing content inside a <div> tag doesn't really do anything or change the content's appearance. It simply acts as a container that holds the enclosed content.

<div> <p>Generic content here...</p> </div>

Applying Styles

One of the most common reasons for using the <div> element is to apply styles. You can apply styles to the element itself, or to any element enclosed within it.

Inline Styles

You can style an element using inline styles, where you apply the styles via the style attribute.

<div style="width:200px;background:#F9EECF;border:1px dotted black;text-align:center"> <p>Generic content...</p> </div>

Embedded & External Styles

You can also style an element using either embedded styles or an external style sheet.

Here's an example of using embedded styles and applying them via the class attribute of the <div> tag:

<!DOCTYPE html> <title>Example</title> <style> div.generic {width:200px;background:#D8FBD6;border:1px dotted black;padding:8px;} div.generic ul {color:green;} </style> <div class="generic"> <p>Generic content...</p> <ul> <li>Item 1</li> <li>Item 2</li> <li>Item 3</li> </ul> </div>

Nested <div> Elements

You can nest <div> elements inside each other. Each of these could have different styles applied.

<!DOCTYPE html> <title>Example</title> <style> div.generic {width:200px;background:#D8FBD6;border:1px dotted black;padding:8px;} div.generic div {width:50%;background:#75CE6F;color:white;border:1px dotted green;text-align:left;padding:3px;} </style> <div class="generic"> <p>Generic content...</p> <div> <p>Nested div content...</p> </div> </div>

Attributes

Attributes can be added to an HTML element to provide more information about how the element should appear or behave.

The <div> element accepts the following attributes.
