css :悬停时的圆角 div
我正在尝试完成一些看起来很简单的事情...
我有 3 个 div
,其中包含一个单选按钮和一些内容:
Content of DIV1,
[] this can be as long or as tall
as wanted
[] Content of DIV2
[] Content of DIV3
使用 其他帖子在这里。 然而,我无法仅针对悬停事件执行此操作,即我希望仅当鼠标悬停在 div 上时才看到 div 周围出现圆形框。 有没有人在某处看到过这样做的例子?
编辑:我已经在使用 Prototype 和 Scriptaculous。 我不能为此添加 jQuery。

It's easy to create rounded corners for each div using any techniques found on other posts here. Yet, I haven't been able to do that only for the hover event, ie I would like to see the rounded box appear around the div only when the mouse hovers over it. Has anyone seen an example of this being done somewhere?
Edit: I'm already using Prototype and Scriptaculous. I can't add jQuery just for this.

这会在 div 悬停时使用 jquery 更改 CSS

this changes the CSS with jquery on the hover of a div

您可能遇到的部分问题在于,在大多数 CSS 实现(以及该技术的浏览器实现)中,div 没有可以附加样式规则的 :hover 方法。
正如 Antony 提到的,jQuery 或许能够解决这个问题。
我将如何攻击它(因为我还没有探索过 jQuery)是将你的 a 标签(确实有一个悬停方法)设置为 display:block,并将所有伴随规则设置为如果它是一个 div,让它展开以填充包含的 div,然后当然,将圆角规则添加到悬停。
另一种方法是用 a 标签包围您的 div,但话又说回来,您仍然设置 display:block、背景和其他不属于 a 的规则。
这都是对语法的残酷滥用,因此在尝试我建议的任何操作之前请先备份您的工作。
祝你好运 - 始终在 div 上保持圆角可能会更容易,并考虑其他可以做的事情来调出悬停效果。
Part of the problem you might be having lies in the fact that in most implementations of CSS (and the browser's implementation of that technology), a div doesn't have a :hover method that you can attach style rules to.
As Antony mentioned, jQuery might be able to get around this.
How I would attack it (since I haven't explored jQuery) is to set your a tag (which does have a hover method) to display:block, with all of the attendant rules you would set as if it were a div, make it expand to fill the containing div, and then of course, add your rounded corner rules to the hover.
Another way is to surround your div with the a tag, but then again, you're still setting display:block, background and other rules that don't really belong in a.
This is all a brutal abuse of the syntax, so back up your work before trying anything I suggest.
Good luck - it would probably be easier to just keep it rounded on the div all the time, and think of something else you can do to call out a hover effect.
我相信你可以用 jquery 做到这一点。

I am sure you could do it with jquery.

CSS 定义了悬停伪选择器,您可以利用它来解决问题,或者使用 javascript 来模拟在 onMouseEnter onMouseOut 事件上向正确的 div 添加/删除 css 类的效果。
Css define the hover pseudo selector you can leverage on it for resolving you problem or use javascript to simulate that effect adding/removing a css class to the correct div on the events onMouseEnter onMouseOut.
