I'm new to the 320 and up template and I'm currently in the process of testing a shell of a site on ie9 but using dev tools to test ie8 & 7 in standards mode.
The site also uses biolerplate html5 and wordpress. I've looked at and tested what I feel is everything I can see and it all looks like it should work in all browsers... it doesn’t
I've uploaded a test site here: http://dev.clear-living.co.uk
If anyone can spot the error that my eyes (blearily) fail to see please point it out for me. I've been looking at this for two days now!
UPDATE: when I say it doesn't work I mean it stays on the 320 width format and doesn't scale up in the browser. Best way of testing this is just to resize the browser window. In the link above this works fine in all browsers except ie7 & 8 in standards mode.
Thanks to @Matt for your comments. Even when I did include respond.js it still wasn't working! I've spent a long, long time trying to get this to work....
...answer.
I got the latest respond.js from github and it worked like a dream! Wish I'd have thought about that earlier!
