HTML <big> Tag (Not supported in HTML5).
HTML <big> Tag was wont to increase the text font size one level bigger than the document’s base font size or surrounding text size, like small to medium, medium to large, etc.
Note:- HTML <big> Tag is not any longer supported by HTML5, so you’ll use CSS to extend the font size.
Example:-
<!DOCTYPE html>
<html>
<head>
<title>HTML Big tag</title>
</head>
<body>
<h2>Example of HTML big tag</h2>
<p style="color:#ff4040">This is paragraph with normal font size</p>
<p style="color:#00bfff">
<big>This is paragraph with font size greater than the previous content</big>
</p>
<h1>Not Supported in HTML5.</h1>
</body>
</html> Output:-
