So im building a portfolio with a gallery. it works great in ff and webkit. for some reason IE8 doesnt like this line of code:

$elem.css('width',window.innerWidth+'px').css('visibility','visible');


is there any part of this that is incompatible with IE?

Yes, the window.innerWidth bit :thumbsup:

$(window).width() (http://api.jquery.com/width/) will return the viewport width.
