It often for the design of the site do not necessarily use the full-color pictures, which is not bad and weigh. But this option could create a completely different design elements, and weigh much less, Another undeniable plus is that for them, and CSS can create. As a result, you can modify the elements themselves, and not to change the picture.

So I would like to know more detail about it. How long is now feasible. Which browsers already supported as a simple files and animation. Just read that Maykrosoftovskom browser with the problem. A fox and Opera is normal work, and about Safari Googley browser does not hear.

Thank you!
