HTML5 and CSS3 are new Web languages that are aimed at creating mobile friendly websites. It is difficult to overstate the importance of a mobile friendly site. The greatest advantage of optimizing your website for mobile Web browsers is that a big percentage of Internet users today access the Internet through such hand-held/mobile devices as Smartphone, feature phones, and tablets.
In mobile Web design, HTML5 and CSS3 go hand in hand. HTML5 elements relate to page structure whereas CSS3 is all about presentation. HTML5 and CSS3 are both in their developmental phase, but this has not stopped many Web designers from successfully using them in major responsive Web design projects.
HTML is the most widely used language in Web design and HTML5 is its latest version. Note that there is no intention to replace previous HTML versions with HTML5 – the aim is to introduce new features and improvements within an existing framework. So, how does HTML5 help make your website more mobile friendly?
HTML5 helps in keeping pages consistent for easy readability by screen readers and other devices and by search engines. HTML5 comes with a simple, browser-based video element which allows you to view video and other media. Note that mobile devices today cannot access such media content as Flash. The video created through HTML5 will have visible controls to play, scrub, and pause.
CSS (Cascading Style Sheets) gives you different options to display your content. The CSS3 features are a component of the HTML5 umbrella and are not a stand-alone entity. CSS3 offers new selectors, properties, and classes which allows for the easy and quick set up of aesthetically pleasing layouts. The reduction of clutter is particularly important in mobile websites since it encourages visitors to spend more time on the site and to see your call-to-action. CSS3, unlike previous CSS versions, is created for all browsers, including mobile browsers. The RGBA Coloring eliminates the need for browser extensions. One-click resizing is possible (when using Safari) with CSS3.
