HTML5, the latest standard of Hypertext Markup Language, is the new technology that will replace Flash. The rich functionality provided by new HTML5 features such as the canvas element, SVG, Web GL, and Web Assembly powers modern web animations and online games.
W3C, in particular, and the entire tech industry are encouraging content creators to switch over to HTML5. Developers are rewriting a lot of existing Flash content in HTML5. A good Flash Player emulator like CheeprX can quickly help view Flash files as HTML5 without manually rewriting them.
