What is the default font-size in IE9?

Question

I looked at this website to see the default styling that IE 9 uses. The body selector looks like this

body {
  display: block;
  margin: 8px;
  zoom: 1;
} 

I would I have guessed that a font-size should have been specified here but it isn't. So what is the default font-size that IE 9 is using?

Answer 1

font-size is being set on every element in that stylesheet in em

eg

h3 {
    display: block;
    font-size: 1.17em;
    font-weight: bold;
    margin: 1em 0;
    page-break-after: avoid;
}

h4 {
    display: block;
    font-size: 1em;
    font-weight: bold;
    margin: 1.33em 0;
    page-break-after: avoid;
}
