To create a big font text, use the JavaScript big() method. This method causes a string to be displayed in a big font as if it were in a BIG tag.
Example
You can try to run the following code to create a big font text −
<html>
<head>
<title>JavaScript String big() Method</title>
</head>
<body>
<script>
var str = new String("Demo Text");
document.write("Following is bigger text: "+str.big());
</script>
</body>
</html>
