An HTML Beautifier is a tool that automatically formats your HTML code to make it more readable and organized. It adds proper indentation, line breaks, and spaces, making the structure of your HTML easier to understand and maintain. Beautifying HTML code is particularly useful when working with large files or when you're collaborating with a team.
Example: HTML Beautification
Before Beautification (Unformatted HTML):
html
<html><head><title>My Webpage</title></head><body><h1>Welcome to my website!</h1><p>This is a paragraph.</p></body></html>
After Beautification (Formatted HTML):
html
<html>
<head>
<title>My Webpage</title>
</head>
<body>
<h1>Welcome to my website!</h1>
<p>This is a paragraph.</p>
</body>
</html>
