如何叠加图像 [英] How to overlay images

问题描述

我想使用 CSS 将一张图片与另一张图片重叠.这方面的一个例子是第一张图片(如果你喜欢背景)将是产品的缩略图链接，链接打开一个灯箱/弹出窗口，显示图像的更大版本.

I want to overlay one image with another using CSS. An example of this is the first image (the background if you like) will be a thumbnail link of a product, with the link opening a lightbox / popup showing a larger version of the image.

在这张链接图片的顶部，我想要一张放大镜的图片，向人们展示可以点击图片放大它(显然，如果没有放大镜，这并不明显).

On top of this linked image I would like an image of a magnifying glass, to show people that the image can be clicked to enlarge it (apparently this isn't obvious without the magnifying glass).

推荐答案

我刚刚在一个项目中完成了这件事.HTML 方面看起来有点像这样:

I just got done doing this exact thing in a project. The HTML side looked a bit like this:

<a href="[fullsize]" class="gallerypic" title="">
  <img src="[thumbnail pic]" height="90" width="140" alt="[Gallery Photo]" class="pic" />
  <span class="zoom-icon">
      <img src="/images/misc/zoom.gif" width="32" height="32" alt="Zoom">
  </span>
</a>

然后使用 CSS:

a.gallerypic{
  width:140px;
  text-decoration:none;
  position:relative;
  display:block;
  border:1px solid #666;
  padding:3px;
  margin-right:5px;
  float:left;
}

a.gallerypic span.zoom-icon{
  visibility:hidden;
  position:absolute;
  left:40%;
  top:35%;
  filter:alpha(opacity=50);
  -moz-opacity:0.5;
  -khtml-opacity: 0.5;
  opacity: 0.5;
}

a.gallerypic:hover span.zoom-icon{
  visibility:visible;
}

我在 CSS 上留下了很多示例，因此您可以看到我是如何决定设计这种样式的.请注意，我降低了不透明度，以便您可以通过放大镜看到.

I left a lot of the sample in there on the CSS so you can see how I decided to do the style. Note I lowered the opacity so you could see through the magnifying glass.

希望这会有所帮助.

为了澄清您的示例 - 如果您愿意，您可以忽略 visibility:hidden; 并终止 :hover 执行，这就是我所做的

To clarify for your example - you could ignore the visibility:hidden; and kill the :hover execution if you wanted, this was just the way I did it.
