Moodle Version: 20120802
Rocket Version: 2012080300 (Latest from git)

After installing Rocket and looking at a course I did not see any borders around topics. As this was the first time I had used Rocket I thought that this was normal. I then had a look at http://features.demo.moodle.com.au and saw that borders are being used although without any margins. I then started looking at the css of both sites and notice that ".course-content .main" had been changed. I modified rocket_style.css and removed Unable to render embedded object: File (important from padding, margin and border and bingo) not found. borders appeared with nice margins and padding. I'm using linux and also noticed the ^M character around some of the .course-content styles which is not seen in the rest of the file so might be good to remove them. Anyway here is my modified section in the style sheet.

.course-content .main {^M
padding : 0px;
margin : 0px;
padding-top: 1px;
border: 0px none;
background: transparent;^M}

I'm not that good with css and not sure what the implications are for removing !important.
