CSS3 + HTML5

HTML5 is the new standard for html. It provides you almost everything you want without requiring additional plugins. It does animation, apps music, movies and it can be used to build complicated applications. It does not care whether you are using a tablet or smartphone, a notebook or smart TV.
HTML5 isn’t proprietary, so you don’t need to pay royalties to use it. It’s also cross-platform, which means it doesn’t care whether you’re using a tablet or a smart phone, a net-book, notebook, ultra-book or a Smart TV if your browser supports HTML5, it should work flawlessly.
Html5 is the combination of three web technologies:→
1. HTML → to build webpage structure,
2. CSS → to enhance look and feel( presentation layer), and
3. Javascript → to add functionality to HTML elements.
