Th3 Core

I have experimented with responsive design using WordPress Twenty Eleven as a base. It's quite easy to get caught in technology fascination and I'm a bit worried about the usability issues that arises when users experience different layout as they resize their browser or change devices. There are so many bad cases out there where you just want to click 'full version' button but it's not there.

On the other hand I have seen some cases where it works. One of my favorites is http://www.jyskebank.dk/. If you browse this site using iPad you can use gestures and swipe the slider up and down.

Instead of thinking one fluid responsive layout you should be thinking mobile, tablet and desktop.

I've been dabbling with a Drupal responsive theme and have seen a few people I respect (and I think that you do too - incredibill and coopster I think) strongly recommend Twitter Bootstrap for responsive HTML5 designs.

Anyway, I haven't tested on a wide range of platforms, but I'll just throw out that if you're going to do responsive image resizing or otherwise push the limits, you can expect some conflicts with, say, jQuery image manipulation for image sliders or overlays. Things like that have to be a bit more carefully constructed than you might be used to.

No you don't. Simply drag your screen size in and out and you'll see that as the size changes it adapts very smoothly - ala Responsive (to screen size change) Design
