XF 2.1 Image on Borders?

[Catsmother]

Hello again

I am trying to add an image to the borders on where my categories are, I have gone through tabs, buttons and blocks but it doesn't seem to go there.
Can someone tell me please?

This is the image I am trying to add.

If you mean like this:


Upload the image to your server.

Add this to the extra.less template:

[data-template="forum_list"]
.block-header
{
    background-image: url('path/to/image.png');
}
