Everyone who was ever interested in CSS3 has already tried it. Now we can generate rounded corners and drop shadows without any superfluous efforts.

But it’s just a superficial level. I had to look into the new possibilities of browsers in more detail, to answer the arising questions like: to what extent gradients with a great number of colour transitions have the cross browser compatibility, where and how is it possible to apply at once a few shadows to the block, for what browsers prefixes of properties are used specifically etc.
