Thread:Skin talk:Chameleon/Horizontal lines under Level 2 headings

Hi. I think this skin is awesome. In terms of simplicity and intuitiveness, this is much better than Vector skin. One problem is that all articles in my wiki is quite lengthy and I found that this skin removes horizontal lines of second level headings.

I'm not really used to css or less. Would anyone help me to revive the line?

Thank you in advance.
