The HTML class attribute is used to specify a class for an HTML element.
Multiple HTML elements can share the same class.

Tip: The
class attribute can be used on any HTML element.Note: The class name is case sensitive!

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:
