I\'m a newbie on CSS3 and all I know is self-learned, reading you guys or any other tutorials so after hours of researching and trial-error, I could really use your help :(.
You could try achieving this with a css gradient. I do something similar on my website's splashpage :

The angled background on the above site is purely CSS3 gradients (with fallbacks of course)
This is done by creating a gradient, starting at 0% with a color of GREY, ending at 50% with a color of GREY as well, then starting another gradient at 50% with a color of DARKGREY and ending at 100% with a color of DARKGREY also.
Basically you are tricking the system. It's technically a gradient, but looks like two solid colors that meet in the middle and are angled.
Take a look at this site to learn more about the properties of a css gradient:
