Let me explain where my mistake came from. I am reading a book about CSS
and slowly learning new things, but these things take time. Meanwhile, I
wanted to sort the padding problem out. Previously I had highlighted the
text and put the padding in through Frontpage settings. The code was an
inline style and it said margin-left: 3. There was no unit shown. From
this I simply tried to guess the proper rule and then turned to you lot
for help. It worked but was clumsy, which is why I wanted it out.
