Example
You can try to run the following code to add special styles to the first line of text
<html>
<head>
<style>
p:first-line {
text-decoration: underline;
}
p.noline:first-line {
text-decoration: none;
}
</style>
</head>
<body>
<p class = "noline"> This line would not have any underline because this belongs to nline class.</p>
<p>The first line of this paragraph will be underlined as defined in the CSS rule above. Rest of the
lines in this paragraph will remain normal. This example shows how to use :first-line pseduo element
