Can I use HTML5 Now to create a website

After all the latest news and talk about HTML5, I would like to know whether I can use HTML5 to create a website as of now. I mean, some features are supported by few browsers, while few features are not yet supported. So is it possible to create a full-fledged website at the current state?

Can you build a website with HTML5?

Webflow lets you create responsive websites powered by HTML5, CSS3, and JavaScript — without actually writing the code yourself.

Do people still build websites with HTML?

Today, HTML is one of many tools used to build the web. Knowing how to write HTML will provide a strong foundation for your career as a web designer and prepare you to learn additional front-end web development skills like CSS and JavaScript.

The question is not whether you can create a full-fledged website, but whether you need its functionality to be identical in all browsers. The answer to the former question is yes. The answer to the latter question is still no.
