#3555 <h3>s invisible in some sections if pictures are deactivated

[Jaleks]

In some sections of Slashdot (hardware.slashdot.org ;
politics.slashdot.org ; games.slashdot.org) the <h3>
headings don't seem to have a background color which
differs from the foreground color (both white).
So if you browse with a graphical browser but have
images deactivated (like Opera is able to do) you
aren't able to read the headings, not knowing what the
article is about until you try to mark the text - at
least not nice if you are used to open many pages in
the background and read them later...
