문제

There are many examples of the following before pseudo technique. But for whatever reason, I'm not seeing the checkmark in Safari and Chrome. Anyone know what is wrong?

CSS

a:visited:before {
 content:  "\2713 ";
}

Webpage content

 <a href="http://www.microsoft.com" target="_blank">is a link</a>

해결책

Styling for :visited has been significantly curtailed to prevent security loopholes, see this this from mozilla

Indeed, :visited and :link items can only be styled by color (SEC7115)

다른 팁

This is because it was almost remove (but some styles such as colors) to prevent security flaws. It was possible to read your whole browser history with.

A small script could easily create links and then check if it has been visited by looking at the style.
