Three HTML5 animation tools: Adobe Edge, Sencha Animator, Tumult Hype

Web interaction via HTML5 can be promising but difficult to learn. These three applications can make a developer's job simpler.

The promise of HTML5, the latest revision of the HTML standard, is a simple one: With greater integration between static HTML and dynamic programming code (such as CSS3 or JavaScript), Web pages can become much more interactive and responsive to user preferences, without the need for plug-ins or memory-hogging multimedia files.

HTML5 represents a significant move forward in Web development because it can provide those features by using the client system's browser, processor and memory to handle most of the heavy lifting. Previously, the limitations of older browsers and prior versions of HTML meant that either the server would have to do much of the processing, or the browser would need a plug-in or add-on to access the dynamic content.

Now, working directly within the browser without the need for plug-ins greatly decreases the amount of time needed to download an interactive page and increases the page's response speed. All that's needed are a few ASCII-based files in HTML5 format and whatever artwork the page requires.

HTML5 also eliminates the binary blocks of unsearchable information found in Flash and other multimedia content. Currently, the bane of any SEO and marketing expert is a Flash-only Web page. With their beautiful graphics and stunning animation, these pages are a delight to the end user -- but invisible to the search engines that need to find and highlight these sites.

In HTML5, this problem is alleviated by the fact that content is found right within the page's source code, right where search engines can get to it. Keeping the content visible within the HTML5 markup code means SEO becomes a much easier proposition to manage on a dynamic Web page. (It's not magical SEO pixie dust -- the content embedded in an HTML5 page must still be fresh and compelling. But at least the SEO barrier to dynamic Web pages has been lowered.)
