Fixes the layout problem on Chrome 33

This should fix the layout on Chrome 33.
If you want to support old browsers you'll also need to add the following code to your container/wrapper element:

```
.container {
    height: auto !important; /* IE6 ignores !important, so this will be overridden below */
    min-height: 100%; /* IE6 ignores min-height completely */
    height: 100%;
}
```
