Google Finally Has Code for App Banners, Will Now Penalize Interstitials

Screen shot of with Chrome developer tools highlighting outline styles. I was thrilled to see the incredibly and wildly inaccessible web site get re-launched recently (here’s an example of the old site from March).

Show/Hide Script-Free (Which Means CSS Only)
