I have currently completed my own WordPress theme and I wanted to do this because it looks better when the blog looks like my website design. I'm not sure how I did it, but I finally managed to, even though I never tried it out before. Now I have some minor changes to do and I can't find where to do it. I would like the blog titles with the grey borders moved more to the left. As you can see the bottom border of the title goes all the way out to the white background. If anyone decides to help me out, what codes files do you need? CSS file or anything else?

Thanks for any help I can get!
