I know how to set a color for a link when it has been visited, but would anyone know how to make an icon appear when a listing has been visited by a visitor?
On my website I show ads (gd classifieds) and beside every classified I show three classifieds from the same category. As these three extra shown classifieds are displayed at random it can now happen that people view the same listing several times as there is no indication they have already seen it.
I don't want the link color to change, but I want to show a nice 'check' icon in the card to indicate that a visitor has already visited it.
