使用奇怪的导航栏的 CSS 悬停问题

我一直有一个问题困扰着我。我知道我这样做的方式很奇怪,并且可能会导致问题,但我想仅使用 CSS 来尝试。我现在已经很接近了,但有一个问题,希望在我放弃之前有人能有一个想法。

基本上我有一个导航栏,可以在悬停时更改图像。与此不同的是,我希望两个图像在悬停时发生变化。因此,我决定也许可以通过将两张图像放入一张更大的图像中并将图像溢出到悬停链接之外来实现此目的。

现在,它在某种程度上可以工作,但是您可以从左到右越过链接,并且它可以很好地显示悬停,但如果您从右到左执行,则不起作用。

我在考虑之后尝试过 z 索引来将链接放在前面,但这显然行不通,因为跨度在其中。

I've been having a bit of an issue which is doing my head in. I know the way i'm doing this is wierd, and was likely to cause problems but I wanted to try it just using CSS. Ive got it quite close now but with an issue and was hoping someone might have an idea before i give up.

Basically I have a navigation bar that changes image on hover. The difference with this is that I wanted two images to change on the hover. So I decided that I could maybe do this by putting the two images into one larger one and overflowing the image outside of the hover link.

Now, it works somewhat, but you can over over the links from left to right and it displays the hovers fine, but if you do it from right to left it doesn't work.

Here is a link to the test http://www.pclwebdesign.co.uk/fruit

I have tried z indexing to bring the links ahead after thinking about it that obviously wouldnt work because the span is within it.

您是否尝试过寻找替代方法?我认为这将是使用一些非常简单的 jQuery 的绝佳机会。我在 jsfiddle http://jsfiddle.net/Ee37A/4/ 上快速草拟了代码给你看。显然,您需要设置 div 的样式并用图像替换文本,但我认为这将是实现您正在寻找的内容的更简洁的方法。

本质上,当您将鼠标悬停在类为“.about”(导航按钮)的 div 上时,jQuery 会找到类为“aboutPicture”(led 照片)的 div 并显示它。当鼠标离开时,“aboutPicture”div 将被隐藏。我只编写了两个不同的li,但是你可以以此为基础。

您可以在此处找到有关 jQuery 的更多信息并下载源代码:http://jQuery.com。您需要创建一个外部 .js 文件来包含 jsfiddle.net 上显示的函数。

Have you tried looking into alternative methods for this? I think this would be a great opportunity to use some very simple jQuery. I did a quick draft of the code on jsfiddle http://jsfiddle.net/Ee37A/4/ for you to see. You would obviously need to style the divs and replace the text with your images, but I think this would be a much cleaner method to achieve what you're looking for.

Essentially, when you mouse over a div with the class ".about" (the nav button), the jQuery finds the div with class 'aboutPicture' (the led photo) and shows it. When your mouse leaves, the 'aboutPicture' div is hidden. I only programmed two different li, but you can use this as a basis.

You can find more about jQuery and download the source here: http://jQuery.com. You would want to create an external .js file to contain the functions that are shown on jsfiddle.net.
