CSS can help us style the first letter of an element using the ::first-letter pseudo-element. Note that punctuation marks, digraphs and content property can change the first-letter.
The following examples illustrate CSS ::first-letter pseudo-element.
Example
<!DOCTYPE html>
<html>
<head>
<style>
body {
text-align: center;
}
::first-letter {
font-size: 3em;
color: sienna;
box-shadow: -10px 0 10px green;
background-color: gainsboro;
}
</style>
</head>
<body>
<h2>Proin ut diam eros</h2>
<p>Donec rutrum a erat vitae interdum. </p>
<p>Integer eleifend lectus sit amet purus semper, ut pharetra metus gravida.</p>
</body>
</html>Output
This will produce the following result −
