| Hello, I recently installed Arc onto a localhost to play with. I'm having some trouble figuring out 3 things. 1- Where I can add or alter CSS, i.e. the page background color (not forum background). I see a few basic things to play with at the top of news.arc, however site color changed the border, and i haven't figured out what border-color changes, because it isn't the border. 2- Thumbnails for if the post link is from Imgur or YouTube 3- Search bar, such as the one on Hacker News Any help/direction is much appreciated |
