Responsive Web Design is here to stay (and that's a good thing!).
Go ahead and check it out in action: From any page on Jonster.com, resize your browser window as small as you can or as large as you can and watch the magic unfold. …Pretty cool, huh?
Why is this beneficial? Well, for starters, it means that no matter what size device your customer is using, be it a mobile phone, tablet or a 30” High Definition monitor, your website will always display exactly as it was intended to.
It also helps with SEO – Search Engine Optimization rankings if you run a mobile version of your site. The reason being is that Google and all major search engines see www.yourdomain.com and mobile.yourdomain.com as two completely separate domains.
With responsive web design, you no longer need the mobile version – it’s automagically done, all the while giving full credit for your site rankings.
