When viewing my site on mobile devices, it doesn't look right because of the width. How can I set the min-width of this style? In the normal stylevar there is an option for doc min-width but not in the mobile. Any help would be appreciated!
There isn't, and most mobiles are going to have pretty tiny widths. you'd have to edit the html and manually place some css. But I wouldn't recommend it.
I spent a lil while this morning working on it. Went into the vbulletin jquery file and edited it in dreamweaver adding a 420px min width. Seems to work fine now.
