From 5a2d74a995f330565e51a523ca1cbca305428ebd Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Simon=20H=C3=B8jberg?= Date: Sun, 27 May 2012 13:07:48 -0400 Subject: [PATCH 01/30] Moved the github fork image locally Often the image would not be able to load when using the external cdn. Instead we now host the image in order for it to always load. Also added some simple transition styles to the image when you hover. --- public/css/app.css | 17 +++++++++++++++++ public/img/fork.png | Bin 0 -> 9267 bytes public/index.html | 6 ++++-- 3 files
