I was trying to adjust the font size for picture captions (make it smaller), but it just wound up expanding the gray border frame. So I thought I reverted back to the original css settings. But now older posts have the gray border where I added a caption, but my most recent posts have no border, just the caption. I also don't see where I could just click one button to revert to default css.
Can someone offer guidance as to how I can go about diagnosing/fixing this problem?
