I came across `html>body` in one of the stylesheets and wanted to know as to why it is used.

```
html>body {
  font-size: 16px; 
  font-size: 78.75%;
}

```

It's called a [Child Selector](http://www.w3.org/TR/CSS2/selector.html#child-selectors).

The reason it's being used is likely because it's a hack to exclude IE6 and below. Those browsers don't understand the `>` selector.
