HTML 5 is the latest version of the hypertext markup language used to build websites, its optimized for the creation of mobile websites and applications. Responsive websites are easily built using HTML5, offering full functionality across all types of devices. Without the need for horizontal scrolling, mobile internet users can browse websites more efficiently. While it offers many of the same features as previous versions, there are several new features that open up world of opportunities. However, some webmasters are skeptical of making the switch to HTML5, fearing its not worth their time or effort. HTML5 also offers offline caching, meaning visitors can load certain elements on a webpage without an active internet connection – assuming theyve visited the site in the past. If a visitors internet connection happens to go down, he or she can still load core elements of the site.
