What is HTML?
HTML (Hypertext Markup Language) is the standard language used to create and structure web pages and applications. It allows developers to organize content into sections, paragraphs, headings, links, images, and more.
While HTML is not a programming language and cannot create dynamic functionality, it provides the foundation for web page structure and formatting, much like a word processor organizes a document.

HTML Syntax
<html
<!doctype html>
<html lang="en">
<head>
<title>Hello World!</title>
</head>
<body>
<div id="content">
<h1 class="title">Hello World!</h1>
</div>
</body>
</html>
What is Minification?
Minification is the process of minimizing code and markup in your web pages and script files. It’s one of the main methods used to reduce load times and bandwidth usage on websites. Minification dramatically improves site speed and accessibility, directly translating into a better user experience. It’s also beneficial to users accessing your website through a limited data plan and who would like to save on their bandwidth usage while surfing the web.
Why minify HTML?
When creating HTML developers tend to use spacing, comments and well-named variables to make code and markup readable for themselves. It also helps others who might later work on the assets. While this is a plus in the development phase, it becomes a negative when it comes to serving your pages. Web servers and browsers can parse file content without comments and well-structured code, both of which create additional network traffic without providing any functional benefit.
To minify HTML files, comments and extra spaces need to be removed, as well as crunch variable names so as to minimize code and reduce file size. The minified file version provides the same functionality while reducing the bandwidth of network requests.
Examples
Before minified
<html
style="color: green">
<!-- this is a comment -->
<head>
<title>Mixed HTML Example</title>
<style>
h1 {
font-family: comic sans;
color: #f0f;
}
div {
background: yellow !important;
}
body {
max-width: 50em;
margin: 1em 2em 1em 5em;
}
</style>
</head>
<body>
<h1>Mixed HTML Example</h1>
<script>
function jsFunc(arg1, arg2) {
if (arg1 && arg2)
document.body.innerHTML = "achoo";
}
</script>
</body>
</html>
After minified
<html style="color: green"> <head><title>Mixed HTML Example</title><style>h1{font-family:comic sans;color:#f0f;}div{background:yellow !important;}body{max-width:50em;margin:1em 2em 1em 5em;}</style></head><body><h1>Mixed HTML Example</h1><script>function jsFunc(arg1,arg2){if(arg1&&arg2)document.body.innerHTML="achoo";}</script></body></html>
