If you have some experience with previous versions of HTML such as version 4.01 but new to HTML 5, here are the first things you need to learn. So what’s new with HTML 5?
1. The doctype definition at the top of the file is simplifed:
The doctype definiton for HTML version 4.01 was something similar to the following
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
The doctype in HTML 5 is now simply:
2. The content meta tag is also simplified
Before HTML 4
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
After HTML 5
All browsers old and new already understand this meta description to my knowledge, so you can use it on any page and it just works.
3. The <link> tag within the <head> element slightly changed
What was before HTML 5
<link type="text/css" rel="stylesheet" href="style.css">
<link rel="stylesheet" href="style.css">
or if you prefer to type inline code rather than an external .js file:
<script> var harikasin = true; </script>
