How to Write CSS Bold Style

In web design, bold style is a common text style that makes text more prominent and easier to read. In CSS, we can achieve bold text in a variety of ways. This article will detail how to use CSS to achieve different bold styles.

1. Using the font-weight property

font-weight property is used to set the weight of text. It can take values of normal, bold, bolder, lighter, or a specific numeric value. bold indicates bold, and normal indicates normal.

The sample code is as follows:

<!DOCTYPE html> 
<html> 
<head> 
<style> 
.bold-text { 
font-weight: bold; } 
</style> 
</head> 
<body> 
<p class="bold-text">This is bold text. </p> 
</body> 
</html>

The sample code is as follows:

<!DOCTYPE html>
<html>
<head>
<style>
strong {
font-weight: bold;

}

</head>
<body>
<p><strong>This is bold text.</strong></p>
