Vantage: How do I remove gray borders on images?

I read some threads about removing gray borders on images but none of them were of any help. I’m using VANTAGE and I’m looking at my “style.css” and can’t find where I need to change “border” to either “0” or “none”. Please help!

Here’s my style.css.
