first of all here is how it looks like :
do you see the nav bar above page content ?
it is defined by div catnav.
elements inside of it are called cat-item-"n"
Originally i wanted to have the color of the top border of this nav in a specific color each time i would change category (links in menu, so cat-item-"n").
There's a class called 'current-cat', which lets me specify for instance the size of font for the selected 'link' I clicked on. But i couldn't find a way to work it out so as to have a different top border color for catnav, everytime i would click on a different cat-item-"n"
I would still very much like to do this..
More generally i would like -as a principle- to separate all my boxes on the page/site with such top border of a specific color (depending on link in nav bar )
I'm really not sure how to achieve this..
Any hint would be greatly appreciated.
thanks in advance !
