h2 bigger than h1 in content

Because of the reset at the beginning of style.css, all h2 are bigger than h1, which is pretty annoying when you work with markdown and such. I think it's because of this code:

div.node h2 {
  border:0px;
  font-size:24px;
  line-height:30px;
  font-weight:normal;
  }

  div.node h2 span.label {
    float:left;
    font-size:9px;
    font-weight:bold;
    line-height:20px;

    margin:5px 10px 0px 0px;
    padding:0px 5px;

    background:#666;
    color:#fff;
    }

... which is used to set the node title. I would welcome having better headers in the .content...
