Hum, you know what, I made a test, it does not seem brilliant.
The example given in the web programming documentation, with “:visited” at the end of the link URL, is displayed in a different color.
But, clicking on a link to a normal web page does not change the color. At least, not the one I put in my previous answer.
A link to the Javascript documentation did change color when visiting it. But not the one to winaero.com
Oh, but the web page where I called the Javascript documentation from was recorded on my local disk.
The documentation has been applied, but it seems some trick still has to be found.
Got a part of it : my answer here is formatted by the stylesheet applied to discourse.mozilla.org, base.scss line 41, so in this case you have to evaluate the conflict rules to know what style is applied. And for that, not forget that scss means compiled stylesheet …
Hum, I wanted to do a test on what you had under your eyes, and … I am afraid I complicated the topic by doing that.
Did you manage to do what you wanted ?
