Well spotted!  Gary had:

  font-family: arial, "sans serif", "new century schoolbook"
  border: 1px;

The line-break is irrelevant, so "border:" and "1px" would be treated as
additional typefaces to try if the preceeding ones aren't found.  It
definitely wouldn't set the border, so yes, this does have an effect!

That isn't true.  Both are valid syntax; they do different things.  What
Gary had:

  #dman tr td

means to apply the following rules to any <td> which is descended from a
<tr> which is descended from an element with id="dman".

Your alternative:

  #dman tr, #dman td

means to apply the rules both to any <td> which is descended from an
element with id="dman", and also to any <tr> which is descended from
such an elment.

In this particular case it may not make any difference (and in practice
<td>-s are always going to be descended from <tr>-s, so that isn't
adding anything), but the syntax Gary had is most definitely not a
"generic problem" and in other circumstances is quite useful.

Cheers.
