One last thing.
If I have a category with like 50 forums and 100 threads. What's the best way to do it?
Do I really need to copy this line 150 times in extra.less or can I make a list that works? Something like:
[data-container-key="node-1,2,3,4,6,7,8"]
{
.p-header
{background:url(PATH_TO_IMAGE_01);}}
[data-container-key="node-45,34,64,34"]
{
.p-header
{background:url(PATH_TO_IMAGE_02);}}
??
