HTML5 is one of the core technologies today and the most accepted markup language for developing web content across the world. HTML5 comes with many new features like the integration of scalable vector graphics and so on. The new features are designed to make it easy to include and handle multimedia and graphical content on the web without having to resort to proprietary plugins and APIs. It is also an attempt to define a single markup language that can be written in either HTML or XHTML syntax. It also includes detailed processing models to encourage more interoperable implementations. HTML 5 extends, improves and rationalizes the markup available for documents. AClick makes use of HTML5 while designing many of its products including Sites so that the users get the best.
