I made quick work of the buttons for those browsers that support border-radius, but that left Opera and IE out of the fun. For them, I developed a different way of rounding the corners, but then I needed a quick way to tell which browsers to give the simple border-radius solution, and which to give the more complex solution.

Modernizr is a small and simple JavaScript library that helps you take advantage of emerging web technologies (CSS3, HTML 5) while still maintaining a fine level of control over older browsers that may not yet support these new technologies.

Modernizr uses feature detection to test the current browser against upcoming features like rgba(), border-radius, CSS Transitions and many more. These are currently being implemented across browsers and with Modernizr you can start using them right now, with an easy way to control the fallbacks for browsers that don’t yet support them.

We visited this concept of re-sizeable background images before… but reader Doug Shults sent me in a link that uses a really awesome technique that I think is better than any of the previous techniques.
