Ok, I've managed to use (what I call a CSS over-ride) on the categories and manufacturers box, but cannot apply it to custom boxes.

All boxes are formatted with the sideboxContent CSS code. I have added the following code to my CSS file to 'over-ride' the sideboxContent for the categories sidebox...

Code:
#categoriesContent {
  padding-left: 6px;
}
This works fine. I've also used the same technique for the manufacturers box.

However, I'm trying to apply this same technique to a custom box (search by price range). As you can probably guess, I've had no luck getting this to work so far.

Anyone able to help, please?
