HTML CSS gradient background and rounded corner

Variety is the spice of life (Il mondo è bello perchè è vario)....


I'm wondering how many solution for obtaining a gradient background I found surfing the web. But it is absolute stunning how much solution there are to obtain rounded corner on border!!!! There are sites with lists of such methods.

Fortunately after trying many of theme I found that CSS 3 support this features (unfortunately with many browsew flavours...). A great example of such techniques is present at http://www.webdesignerwall.com/tutorials/css3-gradient-buttons/. Of course the concept can be applied to whatever element, not only buttons.
