css class or html class:
Class in html and css is a selector. We can define style rules based on the class attribute of the elements. All the elements having that class will be formatted according to there rules. I can put an example here for more details.
<!DOCTYPE html>
<html>
<head>
<title>Html Class</title>
<style type="">
.red{
text-align: center;
color: green;
}
.center{
text-align: center;
color: red;
}
</style>
</head>
<body>
<h1 class="red">My class</h1>
<p class="red">This is my paragraph tag</p>
<h1 class="center">another heading</h1>
<p class="center">this is another paragraph</p>
</body>
</html>
