With the rise of HTML5, a lot of folks wonder whether it might displace plug-ins such as Adobe Flash for rich Internet Application development. Adobe doesn’t see it quite that way. It sees the two technologies as complementary, and it’s putting its money where its mouth is. Adobe Edge is a new technology from Adobe Labs that aims to make it as easy to build complex animations in HTML5, CSS, and JavaScript as it is to do the same in Flash. It’s still rough around the edges, but it does make it possible to do some pretty remarkable things, especially if your goal is to develop banner ads, infographics, or other short animated sequences to be embedded in Web pages.
