Comment 3 for bug 1173426

When compiled, the issue is in the css file under span.key and there are two issues: First, bold is not specified (and this comes from higher up stuff); Second, there is some weird "span.key a" thing so it doesn't get hit anyway.
If I manually edit en.css and make it:

span.key {
  font-weight: bold;
  border-bottom: none;
}

Then things work as expected. So the question becomes how to change things such that the css file(s) will be correct.
For reference the default en.css area:

span.key a {
  border-bottom: none;
}

And note, for "key" there are only <span class="key keycap"> in the entire document. So what is the "a" for?
