Remove space between board list

[imhappi]

Hello,

I have looked around for a solution but I guess I'm not using the right keywords to find it 

All I would like to do is remove the space that divides my boards. I am editing a copy of Curve theme. I'd like to put a black border in to replace the empty space.

If someone could point me to a relevant thread or where I need to look in the .css I'd really appreciate it!!

.....{your custom theme}/css/index.css

Code Select Expand

table {
    border-collapse: collapse;
    border-spacing: 0;
}
