Today we are working with HTML5 and CSS3, but is that enough to give the same potential that we can see on some flash websites? Can that be reproduced using ExtJS ?
For example something similar with what we can see on this template
If we can't do it only using ExtJs, but we need to integrate other technology which one should fit the best ?
Would the effort to develop such app much bigger than using flash ?
Thank you for let me know
