Would anyone be able to tell me how [if it's possible] to have different category header colours?
div.cat_bar
Is where I can change all colours, but I am unsure how to change the default skin so that I can have multiple colours instead of just one.
Can CSS with SMF target forum ID's as a way to change the colour of the headers?
Yes
#category_1.cat_bar {
background-color: red;
}
Thank you, Diego.
