Hello.

I’m currently saddened I cant reference the browser width in ruby. I’m  
trying to use a periodically\_call\_remote function to trigger a ruby  
function to change my css based on screen resolutions, but i cant pull  
the screen resolution into a ruby variable!!

How can you do this? I tried a conditional in my  
periodically\_call\_remote, so i can trigger a function call for one  
resolution, but not other!

(this is for swapping iphone resolutions)

anyone?
