We have a plan for the home page navigation, we just need to get it done in code. Home page navigation, I say specifically, because this is likely only going to be used on the homepage. It would be a bit much to use on every internal page, the way it’s designed now. Point being, we can put this into our home.php template.
We write a bit of simple semantic markup according to our design, and then begin to style it. Of course this is a perfect “module” so we can separate the SCSS into it’s own file. We use Compass for the CSS3 bits.
