No problem with Hover state, but visited state doesn’t work. If you compared home link, contact link and tarif link they don’t have same behaviour.
My aim is the link become red when it have been visited staying red when user visiting the other pages.
As you can see contact link stay red but the problem is that it’s red even if it has not been visited.
Contact link and tarif link doesn’t stay in red however they have exactelly same classes.
