I Tried Everything! Display:inline Won't Work On Ie

I'm very new to HTML5 and I got stuck. Here is the site I'm coding. It is OK in Chrome, Firefox and Safari. But in IE there are many problems. But I'll ask the most annoying one:

Solution 1:

IE6-8 do not recognize HTML5 Elements such like nav. You need to "register" them to those IEs so you can use css selectors on them. Take a look at this SO question or this article on how to achieve that.

Also you should avoid inline styles at all costs. Put them in your external css since you already have one.
