Setting Font Size with Em in CSS

To set the font-size property in CSS, you can use em. This is beneficial when you need pixel accuracy for the text. By default 1em = 16px, and 2em = 32px.

Example

 Live Demo

<!DOCTYPE html>
<html>
<head>
<style>
.demo {
   text-decoration: overline;
   text-decoration-color: yellow;
   font-size: 1.3em;
}
</style>
</head>
<body>
<h1>Examination Details</h1>
<p class="demo">Exam on 20th December.</p>
<p class="demo2">Exam begins at 9AM.</p>
</body>
