I’m sure you’ve seen it by now – websites with different versions depending if you’re viewing it on a computer (laptop & desktop), tablet & iPad, or mobile / iPhone.  The trick is Responsive Layout designs.  These are website designs with one set of code but automatically adjusts depending on the screen size (even knows when you turn your iPad or iPhone from Portrait to Landscape modes!)

Otherwise, you’ll need a team of designers to pull off one design for the BlackBerry, another for the iPhone, the iPad, netbook, Kindle — and all screen resolutions must be compatible, too.

Without getting into technical details, here are some awesome responsive Tumblr themes that will look great on your computer, tablet, or mobile devices.
