Responsive HTML 5
Responsive designs are essential for today’s websites. The ability for a website to fit both desktop computers and mobile devices is no longer a “nice to have feature”. It’s become a vital requirement.
People expect to be able to use their tables and smartphones to view the web. If a website is not mobile friendly, people will search for competing websites that are. People love to use their mobile devices, therefore a website needs to be an enjoyable experience.
