HTML 5 is the first new revision of standards since HTML 4.01, which was released in the 1999th. It’s a collaboration of the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG). By 2006. two groups have worked separately, WHATWG was working with web forms and applications, and W3C with XHTML 2.0. Fortunately they decided to join forces and create a new version of HTML, which has surprised all. Some of the newly introduced elements are <video>, <audio>, <canvas>, <header>, <footer>, <article>, <section>
HTML5 offers a lot more features than its predecessors, such as:
CSS is an abbreviation of Cascading Style Sheets. It is a language that we use to describe the presentation of the document written using markup (HTML) language. As the web evolved, originally there were elements for the definition of presentation (<font>, <tag> etc.) thrown into HTML, but it was fast enough identified the need for stylistic language that would relieve HTML the need of displaying content (which is primarily intended to HTML ) and its shaping (which we now use CSS for). In other words, the style defines how to display HTML elements. With CSS, appearance and page layout is governing. CSS3 offers a lot more rules for the various editing options of website appearance.
