HTML5 (HyperText Markup Language) is the next version of the language used most commonly to create Web pages and content on the Internet. One of the biggest changes in this version is how the code will handle playing video and audio elements on a Web site. By adding a new standardized video tag to the language, videos can be embedded in the same way as images on a page and controls and sizing can be customized without the need for another company's plug-in like QuickTime or Flash.
HTML5 is a work in progress and accessibility is one of the major components still being discussed. One downside to this new version is that not all browsers play the same video codecs. This means that designers will have to offer video in a few different formats to make sure that all online browsers can see the video. If a standard codec is adopted by the design community, easily viewing multimedia elements on a Web site will become universal for users. Today, without the proper upgrades to personal computers, some users may still require separate players to view video, which can alter the display of a Web site and render some features unavailable.
