Well, cleaaring the cache must’ve been delayed because the regular state image and hover state image now line up in Firefox, Chrome and IE.
Still a shift in mobile (media max-width: 768px) with the hover state shifting about 60px or so above the regular state.
Just started working on this today so the logo size isn’t set at 600×200.
May go to 450×150.
Might end up making the logo into a rollover.
