HTML5 is some thing not impressive but it is actually more responsive

HTML5 = HTML + CSS3 + JS

So, what is HTML5 and why it is responsive not impressive ?

HTML5 is most commonly used Front End and brought the tremendous change in the User Interface for the last couple of Years. Twitter Bootstrap is one of such kind released by Twitter, downloaded by a lot of developers and embedded their skill set inside to bring out the defined design of their own to the visibility.

Right Now, Flat UI is coming with such a component based thing. You can design your own website with your own HTML5 with the help of CSS, JS they provide. Easy to use this API to make a User Interface is a lot great. As previously revised, HTML5 is most commonly used as interface to develop the application rather than it’s OWN native.

Over the years of development, Flat UI assures that this UI will bring out the most fascinating designing after the release to the public. Consideration based on the needs of the HTML5 website developers, this UI is been developed and probably it contains same elements as the PSD version. With the help of the Flat UI you can save time to write a long code of CSS or LESS. It contains many basic and complex components like buttons, inputs, groups, selects, radiobuttons, tags, menus, Progress Bar, navigation element and more awaiting.

But not only Flat UI there is a lot of responsive theme creating plugins available in the net. I recommend Twitter Bootstrap to start with.
