Is there a quick way to convert a Flash site to HTML5? That's the question we're being asked more often as hardware manufacturers drop their support for Flash and Adobe's once major software starts getting marginalized. While Adobe still has plans for future Flash development, it is clearly no longer the medium of choice for current and future web projects.
The answer to the conversion question is - it depends. There are technologies for converting basic SWF animations into HTML5 and CSS. The resulting animation's code will still need to be cleaned by hand, but it does not need to be recreated from scratch. This will only work with simple, timeline-driven animations, such as banners, as all project assets are exported as individual elements and timeline is converted into script.
