Is there any reason why my site would render properly in IE8, 9, and Chrome (all same versions) on my machine, and then render differently on another machine?
I have attached screenshots of a site I'm developing. These shots are from my client. In all three cases, this site renders just fine on my end using the same exact browsers.
My client also tells me that font colors are not showing up properly in the latest version of Safari, when they show up just fine on my machine.
Any direction would be very helpful. Very urgent.

What it looks like in Chrome

What it looks like in IE8

What it looks like in IE9
