CSS- Highlight a div when the id is linked to using an anchor?
提问by harley_woop
What I am attempting to do is to highlight a div with a certain id, when It has been referred to by an anchor on another page IE:
我试图做的是突出显示具有特定 id 的 div，当它被另一个页面 IE 上的锚点引用时：
User clicks link href="qw.html#test", when the page is loaded, then the div with the id="test"is highlighted so that the user can see it clearly.
用户点击 link href="qw.html#test"，当页面加载时，带有 的 divid="test"会突出显示，以便用户可以清楚地看到它。
I'm sure that I've seen a CSS3 example where a div is highlighted if it was linked to. Or was it JavaScript?
我确定我看过一个 CSS3 示例，其中如果 div 被链接到，则会突出显示它。或者是 JavaScript？
