I want to rewrite this line without using jQuery so it can be applied quicker (and before the downloading of the jQuery library). The line is...

```
$(document).ready(function() { $('body').addClass('javascript'); });

```

If I added it to the `html` element instead, would I be able to leave off the DOM ready part? One problem with this though is the validator doesn't like the class attribute on the `html` element, even if it is inserted with JS.

So, how would I rewrite that without jQuery?
