Css div class attributes

HTML class Attribute

The HTML class attribute is used to specify a class for an HTML element.

Multiple HTML elements can share the same class.

Using The class Attribute

The class attribute is often used to point to a class name in a style sheet. It can also be used by a JavaScript to access and manipulate elements with the specific class name.

In the following example we have three elements with a class attribute with the value of «city». All of the three elements will be styled equally according to the .city style definition in the head section:

Example

In the following example we have two elements with a class attribute with the value of «note». Both elements will be styled equally according to the .note style definition in the head section:

Example

My Important Heading

This is some important text.

Tip: The class attribute can be used on any HTML element.

Note: The class name is case sensitive!

Tip: You can learn much more about CSS in our CSS Tutorial.

The Syntax For Class

To create a class; write a period (.) character, followed by a class name. Then, define the CSS properties within curly braces <>:

Example

Create a class named «city»:

London is the capital of England.

Paris is the capital of France.

Tokyo is the capital of Japan.

Multiple Classes

HTML elements can belong to more than one class.

To define multiple classes, separate the class names with a space, e.g. . The element will be styled according to all the classes specified.

In the following example, the first element belongs to both the city class and also to the main class, and will get the CSS styles from both of the classes:

Example

London

Different Elements Can Share Same Class

Different HTML elements can point to the same class name.

In the following example, both and

point to the «city» class and will share the same style:

Example

Use of The class Attribute in JavaScript

The class name can also be used by JavaScript to perform certain tasks for specific elements.

JavaScript can access elements with a specific class name with the getElementsByClassName() method:

Example

Click on a button to hide all elements with the class name «city»:

Don’t worry if you don’t understand the code in the example above.

You will learn more about JavaScript in our HTML JavaScript chapter, or you can study our JavaScript Tutorial.

: The Content Division element

The HTML element is the generic container for flow content. It has no effect on the content or layout until styled in some way using CSS (e.g. styling is directly applied to it, or some kind of layout model like Flexbox is applied to its parent element).

Try it

As a «pure» container, the element does not inherently represent anything. Instead, it’s used to group content so it can be easily styled using the class or id attributes, marking a section of a document as being written in a different language (using the lang attribute), and so on.

Attributes

This element includes the global attributes.

Note: The align attribute is obsolete; do not use it anymore. Instead, you should use CSS properties or techniques such as CSS Grid or CSS Flexbox to align and position elements on the page.

Usage notes

Accessibility concerns

The element has an implicit role of generic , and not none. This may affect certain ARIA combination declarations that expect a direct descendant element with a certain role to function properly.

Examples

A simple example

div> p> Any kind of content here. Such as <p>, <table>. You name it! p> div>

What are valid attributes for the DIV element in HTML?

What are all the valid DIV attributes? Based on this link, it appears only class , id , title . Is that correct? Meaning, the for attribute and others is not valid for DIV ?

I’m really disappointed that this got answered. With the w3c out there, easily searchable and easily discoverable. We are just proliferating this kind of lazy question by providing answers. p.s. to those who answered, this isn’t even a programming question!

@Lazarus — I think the best comment would be to educate JasonK on the proper place to find this information like Sinan Ünür has done. Rather than calling his question lazy. He may be new to web development and not actually know where to find the answer.

@Lazarus — Sinan Ünür did educate him on how to find this information. «See W3C specs:» He was also helpful in providing the information in his answer rather than blindly linking to the W3C spec. I’m sorry, but this site becomes useless when one answers with «Search using Google». or refuses to answer at all when they know the information.

@Lazarus This is the first search result from google, «non-lazy» people in the future searching for this will come here.

• id , class (document-wide identifiers)
• lang (language information), dir (text direction)
• title (element title)
• style (inline style information)
• align (alignment)
• onclick , ondblclick , onmousedown , onmouseup , onmouseover , onmousemove , onmouseout , onkeypress , onkeydown , onkeyup

for is for label and specifies the id attribute of the input element to which the label applies.

The div element has no special meaning at all. It represents its children. It can be used with the class , lang , and title attributes to mark up semantics common to a group of consecutive elements.

Note: Authors are strongly encouraged to view the div element as an element of last resort, for when no other element is suitable. Use of more appropriate elements instead of the div element leads to better accessibility for readers and easier maintainability for authors.
