Danke Shon, Jason, glad you’re finding the stuff useful!

I’ve not played with LESS at all, but am über interested, mostly because it provides CSS variables, which is something I’ve been dreaming of for some time…

But there is no need to use LESS in order to do responsive design, you just have start from the right starting point and build-up appropriately.

I’ve been doing a lot of responsive design lately and have been dying to put together a post about it, but just haven’t made the time to do so. In the mean time, Tweeted this the other day, you might find it useful:

BTW, #ff5e99 isn’t me, it’s straight from HTML5 Boilerplate, so blame Paul & Divya! :-)

Prost,
