: What is that flash can do but css3 cant do I am not asking to prove what is better, and since this is a forum for graphic Designers..i would like to have a list of limits and possibilities.

Flash used to be very justifiable for web content as it was a streamlined means of producing rich graphics and animation. However, there is currently very little that you cannot replicate using a combination of HTML5/CSS/Javascript, and if you use php or a similar language to communicate with a server you can create dynamically generated content much more securely than with flash. Decompiling a flash file is actually pretty easily accomplished, so arguments that state that flash is more secure are not really on point. As of now, I think flash is really only still relevant because so many designers and developers are still familiar with the platform from when it was pretty much the only viable option for rich web media. If you are already familiar with flash, by all means use it where it's appropriate (but also realize it is becoming appropriate for fewer and fewer contexts as time goes on), but if you have to learn some way of delivering rich content from scratch, I really wouldn't bother with it at this point.

You can't compare Flash to CSS3. Try comparing it to HTML5 (which works quite well with CSS3).

This said, Flash has one key advantage over what HTML5 does -- Flash locks away its content behind a single file, so it's harder to reverse-engineer than an equivalent HTML5 setup. It also works better with older browsers that aren't able to handle html5.

This said, Flash is increasingly becoming harder and harder to justify in order to make online content mobile-friendly. You may as well make your life easier and switch over to the mobile-friendly chimera of HTML5/CSS3/Javascript.

Flash lets you create complex animations and interactive interfaces such as games, and it's very powerful for those.

But flash is becoming obsolete for web (among other well known reasons: it takes longer to load, it's inconsistent for mobile and tablet experience, it doesn't index any information), while CSS3 is growing, next to javascript, as the preferred method for web animation.

For desktop, flash will probably work in most computers and browsers. CSS3, on the other hand, is not supported by earlier versions of Internet Explorer.

Between flash and css3, I choose Javascript! It works for everyone that has it enabled, and it lets you create any interaction your heart dreams of. And you don't need canvas to do transitions, you can perfectly use css2 positions.
