It was hard to get it work on Internet Explorer and make it consistent between browsers. There are still some issues with CSS to be resolved.
For example, with Firefox, the text in the input field (search, newsletter subscription) displays higher than in IE or Safari.
Another strange thing is that with Safari only, when submitting a form... nothing happens. I tried to show the search button instead of using the return/enter keys, but it does not work either.
Firefox is showing your username and password text outside of the login box, also I am not sure if it is intentional or not, but I notice that the standard box around the main content is missing
