I am struggling now for a few days with a supposedly simple CSS problem. I want to style hyperlinks. In order to apply custom CSS, I tried Joe’s CSS Box stack (BTW: I have the same issue with DeFliGra’s CSS on the fly stack).
The hover color is applied, but the link color is not. Interestingly I can easily change the background color of “.cssbox a:link”. On the website, where I observed this issue for the first time, it was exactly the other way around: the link color was applied, but the hover color was not.
Your theme is applying grey text to visited links, so you will want to target those too with the :visited pseudo selector. You have set your test link to the same link as the page being viewed, which is why it is taking visited colouring.
.cssbox a:visited{color:blue}
Ask the theme developer for an update to fix the missing theme colours. I still see things like %colour_links% in your source code.
One additional question: do you have any idea, why it works only if I add the CSS on each page? It does not work if I add the code to Settings > Code > CSS.
If you are using RW8, I think there is a bug that prevents CSS being written into the page. I have not been able to replicate it myself, but a couple of others have hinted there have been problems for them and have reported it to support.
