In Chrome, the default style looked something like this:

[kaleb]

:-webkit-any(article,aside,nav,section) :-webkit-any(article,aside,nav,section) h1 {
    font-size: 1.17em;
    -webkit-margin-before: 1em;
    -webkit-margin-after: 1em;
}

IE 9 had the same font size. I could not find a good way to be as concise as the above example that works cross browser.

There may be other headers within the new semantic tags that should be normalized.

Thanks but not happening. See #29
