What is the difference between html and html 5

Answer 1

Html5 is the latest version of HTML which adds new features such as semantic elements and support for multimedia content.

Semantic elements reduce the use of div tags, which allows your Web page to be more meaningful to the browser and other users who view your code.

For example <div id="nav"> is replaced by <nav> in Html5.

Answer 2
