Can Vbulletin adjust size based on client? iPad related

[ggiersdorf]

I have a site where I used to have a fixed resolution 980px for my forum. However alot of users complained that they would like to have a more fluid size so I set the css to 85% of the screen and everyone loved it.

That was until some iPad users started complaining that it was to small now (ads overlapping etc.) So I was wondering if there is a way to do an IF THAN type of thing were if vbulletin determines your on the ipad it makes it a fixed size otherwise the site stays at a 85% of your screen size??

Any help would be appreciated.

Thanks!
