Flash has been a mainstay of animation and video on the web. The introduction of HTML 5 content has helped push the development of converting flash animations.
The first step is to test to see if your browser works with HTML 5.
Go to http://html5test.com/ and see how compatible your browser is. (You may need to add or remove add-ons or plug-ins to make your browser more compatible).
Some advantages of HTML5 are
- Ability to run on mobile devices and tablets/pads
- Smaller file sizes in some cases over flash leading to quicker downloads and faster page response
- Rich content I.e video, animation and interactivity without the need to load extra plug-ins into your browser
- Adding or using Forms to websites that would not necessarily support forms because if java restrictions.
- More elegant use of CSS for elegant banners, forms and advertising widgets and a larger variety of font support helping web pages easier to read.
- Offline browser cache support. Enabling this feature will allow your users the ability to view content on the page even after they have disconnected from the web.
- Can use client side data tracking called sessionStorage and localStorage as an alternative to cookies which could be easily turned off by the user.
