Responsive Website Designing
Google has also decided this is the case, and is promoting sites that are mobile friendly in its search engine results pages on mobiles. But even if this were not the case, we would (and did) opt to design websites using responsive web design techniques for the simple reason that it is the most effective way to make sure your website is optimised for all devices being used. On a fundamental level, most desktop screens are orientated to landscape and most smartphones in portrait. Sure the phones get turned around, but having a site fixed in one position is clearly going to run into problems.
