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".

HTML Class Attributes
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 <div> elements
with a class attribute with the value of
"city". All of the three <div>
elements will be styled equally according to the .city
style definition in the head section:
<!DOCTYPE html>
<html>
<head>
<style>
.city {
background-color: tomato;
color: white;
border: 2px solid black;
margin: 20px;
padding: 20px;
}
</style>
</head>
<body>
<div class="city">
<h2>London</h2>
<p>London is the capital of England.</p>
</div>
<div class="city">
<h2>Paris</h2>
<p>Paris is the capital of France.</p>
</div>
<div class="city">
<h2>Tokyo</h2>
<p>Tokyo is the capital of Japan.</p>
</div>
</body>
</html> In the following example we have two <span> elements
with a class attribute with the value of
"note". Both <span>
elements will be styled equally according to the .note
style definition in the head section:
<!DOCTYPE html>
<html>
<head>
<style>
.note {
font-size: 120%;
color: red;
}
</style>
</head>
<body>
<h1>My <span class="note">Important</span> Heading</h1>
<p>This is some <span class="note">important</span> text.</p>
</body>
</html> 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 {}:
Create a class named "city":
<!DOCTYPE html>
<html>
<head>
<style>
.city {
background-color: tomato;
color: white;
padding: 10px;
}
</style>
</head>
<body>
<h2 class="city">London</h2>
<p>London is the capital of England.</p>
<h2 class="city">Paris</h2>
<p>Paris is the capital of France.</p>
<h2 class="city">Tokyo</h2>
<p>Tokyo is the capital of Japan.</p>
</body>
</html>
Multiple Classes
HTML elements can belong to more than one class.
To define multiple classes, separate the class names with a space, e.g. <div
class="city main">. The element will be styled according to all the
classes specified.
In the following example, the first <h2> element belongs to both the
city class and also to the main class,
and will get the CSS styles from both of the classes:
<h2
class="city main">London</h2>
<h2 class="city">Paris</h2>
<h2
class="city">Tokyo</h2>
