使用带有样式链接的IE8的意外CSS结果 [英] Unexpected CSS result using IE8 with styling links

问题描述

我已经使用CSS对链接进行了样式设置，如下例所示.

I've styled links using CSS like the example below.

这在Chrome中按预期工作，但是使用IE8，我遇到了这个问题:

This is working as expected in Chrome however with IE8 I'm having this problem:

首次访问该页面时，所有链接的下划线都没有达到预期的水平.

When you first visit the page all links do not have underline as expected.

如果我将鼠标悬停在它们上，它们将按预期显示下划线.

If I hover on them they get underlined as expected.

如果随后访问该链接，则下划线会按预期消失，但是如果我再次将鼠标悬停在其上，则不再显示下划线.

If then visit the link the underline disappears as expected however if I again hover on them I don't get the underline anymore.

有什么想法吗??

谢谢

a:link {color:#0064cc;font-family:Arial;font-size:13px;text-decoration:none !important;}     
a:active {color:#0064cc;font-family:Arial;font-size:13px;text-decoration:none !important;}     
a:hover {color:#0064cc;font-family:Arial;font-size:13px;text-decoration:underline !important;}  
a:visited {color:#0064cc;font-family:Arial;font-size:13px;text-decoration:none !important;}  

推荐答案

您的问题出在您的链接未在

Your problem comes from the fact that your links aren't styled in LVHA order. You should style them with :link first, then :visited, then :hover, then :active for consistent cross-browser results.

此外，应用于:link的任何样式都无需重新应用于:visited，:hover或:active，除非您想用其他值覆盖它.例如，当您为:link声明text-decoration:none时，无需将其放在除:hover之外的任何其他定义中，在该定义中您要将其覆盖为none.由于除:hover以外的所有样式都相同，因此您可以在此处略过LVHA顺序:

Additionally, any style applied to :link doesn't need to be reapplied to :visited, :hover, or :active unless you want to override it with a different value. For example, when you declare text-decoration:none for :link, you don't need to put that in any other definitions except for :hover, where you want to override it to none. Since all of the styles except for :hover are the same, you can kind of bypass the LVHA order here:

a:link, a:visited, a:active {
    color: #0064cc;
    font-family: Arial;
    font-size: 13px;
    text-decoration: none;
}
a:hover {
    text-decoration: underline;
}

希望这会有所帮助！

尽管您的问题与!important的使用无关，但通常最好避免使用它.它导致了一些非常非语义的CSS.最好全面了解CSS选择器的应用顺序(这并不像您想的那么简单！).请查看MDN的文档了解更多信息.

Although your issue isn't related to your use of !important, it is generally a good idea to avoid using it. It leads to some pretty non-semantic CSS. It's better to have a comprehensive understanding of the order in which CSS selectors are applied (it's not as simple as you might think!). Check out the MDN's documentation for more info.
