HTML5 is the latest version of Hypertext Markup Language (HTML), used to structure and present content on the web.
It introduces new semantic elements, multimedia support (audio and video), improved form controls, and features for creating interactive web applications. HTML5 aims to make web content more accessible,
efficient, and compatible across various devices without relying on external plugins.
1. What is HTML5 ?
