A class in CSS is a way of targeting specific HTML elements on a page. Classes are used to group elements together so that you can style them in a uniform way.
Example:
Let’s say you want to style all of the
elements on a page to have a font size of 14px. You can create a class in CSS like this:
.paragraph {
font-size: 14px;
}
Then all you have to do is add the class=”paragraph” attribute to all of the
elements you want to style.
