Question

I’d like to start using HTML5’s basic features, but at the same time, keep my code backwards compatible with older browsers (graceful degradation). For instance, I’d like to use the cool CSS3 properties for making rounded corners. Is there any available tutorial for writing gracefully degradable HTML5 ?

Additionally, what browsers should I support so that my app. is functional for at least 95% of visitors? What are the ways to test those browsers painlessly ?

When talking about HTML5 or CSS3, you should head over to:

When can I use…

As can be seen, we are still far far away from using that.

Also, since old versions of the browsers won’t support HTML5 or CSS3, however, you can do what is known as:

Progressive Enhancement and Graceful Degradation

Here are some resources also:
