I found the CSS to change the colour of the thin strips along the bottom of the sideboxes:
.leftBoxContainer, .rightBoxContainer {
margin: 0em;
border: 1px solid #9a9a9a;
border-bottom: 5px solid #5503d1
}
and that worked, but at the same time all the white space between the boxes disappeared so they're on top of each other. I can't find where to fix this. And anyway why would changing the colour of that strip do that?
