The latest published HTML version is HTML5 developed by World Wide Web Consortium (W3C) and WHATWG. It has new elements that support multimedia such as <video>, <audio> and <canvas>. HTML5 works hand-in-hand with the latest published version of CSS which is CSS3. CSS3 “has been split into ‘modules’. It contains the ‘old CSS specification’ (which has been split into smaller pieces). In addition, new modules are added.” Some of these modules are the text effects, box model, 2D/3D transformations , etc. CSS3 is still under development while HTML 5 is undergoing its first minor revision called HTML5.1.
