Add to Cart hides Text

[thorrrr]

Hi guys & Girls need some help i have my cart running and most things seem fine. But i installed the Stock by Attribute pluggin which has worked fine for what i wanted in relation to stock control. But during the upload it has changed my shopping area. If you check my site www.clicspecs.com and and select an item then press add to cart the whole cart area goes light grey and the text disappears or is very faint. I do not want the grey box to overide the default colours but do not know how to stop it overriding the default css for the page!

Can anybody help me alter this please explain in a simple way as i new to Zen Cart

Sorted now
