<div>
Definition
The <div>
element is a container that is commonly used in HTML to group other elements together and apply styles to them. It is a block-level element that creates a rectangle on the page in which other elements can be placed. The <div>
element does not have any inherent semantic meaning, meaning that it does not convey any specific information about the content it contains. Instead, it is used as a tool for organizing and styling content on a web page.
One common use for the <div>
element is to create a grid layout for a page. By nesting <div>
elements within each other and applying appropriate CSS styles, a developer can create a flexible grid that can be used to layout a page's content. The <div>
element can also be used to create sections on a page and apply specific styles to those sections.
Another advantage of the <div>
element is that it can be easily styled using CSS. By applying class or id attributes to the <div>
element, a developer can target specific <div>
elements and apply styles to them. This makes it easy to create complex layouts and apply consistent styles to groups of elements on a page.
In summary, the <div>
element is a versatile and widely-used container element in HTML. It is used to group other elements together and apply styles to them, and can be used to create complex layouts for web pages.
Examples
<div id="page-wrapper">
<div class="header">
<h1>Hello, World</h1>
</div>
<div class="content">
<p>Welcome to my page!</p>
<p>This page is an example of the div element in use.</p>
</div>
<div class="footer">
<p>Goodbye, World</p>
</div>
</div>
In this example, the <div>
element is used to create a wrapper for the entire page. This <div>
element has an id attribute of "page-wrapper", which can be used to apply styles to the entire page. Inside of this wrapper, there are three nested <div>
elements: one for the header, one for the main content, and one for the footer. Each of these <div>
elements has a class attribute, which can be used to apply styles to specific sections of the page.

Best Practices
- Use the
<div>
element to group related elements together and apply styles to them. - Avoid using the
<div>
element for any semantic purposes. Instead, use elements with specific semantic meaning, such as<header>
,<footer>
,<article>
, etc. - Use the
class
andid
attributes to apply styles to specific<div>
elements. - Use CSS to specify the alignment, size, and other styles for
<div>
elements and their content. - Use the
<div>
element to create a grid layout for your page, but avoid using it for every element on your page. - Use descriptive and meaningful names for the
class
andid
attributes of your<div>
elements, to make your code easier to read and maintain.
Accessibility Considerations
The HTML <div>
element is a generic container for other HTML elements, and does not inherently have any accessibility considerations. However, it is important to consider accessibility when using the <div>
element in the context of a larger web page or application.
For example, if you are using the <div>
element to group related content on a page, you should ensure that the content within the <div>
has a clear and descriptive label. This can be accomplished using the aria-label
attribute, which allows you to provide a text description of the element and its content. This can help users of assistive technologies, such as screen readers, understand the purpose and context of the content within the <div>
.
Additionally, you should ensure that any interactive elements within the <div>
, such as links or buttons, are properly labeled and keyboard-accessible. This will help users who may not be able to use a mouse or other pointing device to interact with the page.
