HTML5 not only brings new semantic tags, but it also introduces new tags and technologies such as <canvas> and <video> that help improve your overall web experience.
New technologies out-of-the-box, better user experience
HTML5 not only brings a new set of tags to use, but it also includes new APIs (Application Programming Interfaces) that enable browsers to do really neat things - without having to download any extra plugins or scripts.
Among the many new tech features of HTML5 include video embedding (using the <video> tag), drawing on screen using javascript (using the <canvas> tag) and locating where a user is from (using the geolocation API).
