Paragraph <p> tags not working in blogger template

For some reason, <p></p> tags weren't working in my blog's style.

I went digging in the template, and located this little gem.

.post-body p {
  line-height: 1.4em;
  /* Fix bug in IE5/Win with italics in posts */
  margin: 0;
  height: 1%;
  overflow: visible;
}

I changed it to this:

.post-body {
  margin:0 0 .75em;
  line-height:1.6em;
}

And voila, paragraph tags actually, well, make a paragraph!
