On some other browsers it works.Thanks.Edit: it doesn't work in chrome either. What am I doing wrong?Edit: changing case did not affect it.Edit: changing a to a:link did not affect it.Edit: changing color works, just not font-weight.Edit: workaround was to change accessibility to ignore web colors. I do not have access to the source, so I had to do it this way. 解决方案 Actually, this has nothing to do with case sensitivity. This is a security feature. The functionality of :visited pseudoclass has been restricted in many modern browsers (Fx4, IE9, Chrome) to prevent CSS exploit: read about it here.Nowadays, getComputedStyle() in these browsers usually returns values for visited links as if they weren't visited. However, I can simply imagine circumventing of that: using font-weight for visited links, the element's width changes so browsers that would allow changing font-weight for :visited links wouldn't actually fix the security hole.Thus, there's no workaround for this issue. 这篇关于为什么不这样：访问css风格的工作？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 10-24 23:05
