问题描述

因此，我真的是使用CSS的新手，我需要在和图片的顶部添加3条垂直的红色线条，这些线条必须将图片分成4个大小相等的部分。图片的大小始终为465 * 346，到目前为止，我标记的内容如下：

So I'm really new using CSS, I need to add 3 vertical red lines on top of and Image, the lines have to split the image in 4 equally sized parts. The size of the image is always 465*346 and the mark up I have so far looks like this

<div id="preview-image-wrapper">
   <span class="firstOverlayLine" ></span>

推荐答案

您可以像这样原始处理-在图像上浮动1px宽的跨度，并保留原始HTML：

You can do something raw like this - floating 1px-wide spans over the image, keeping your original HTML:

div {
  width: 465px;
  position: relative;
}

span {
  position: absolute;
  display: block;
  height: 346px;
  width: 1px;
  background: red;
}

.firstOverlayLine {
  left: 25%;
}

.secondOverlayLine {
  left: 50%;
}

.thirdOverlayLine {
  left: 75%;
}

<div id="preview-image-wrapper">
   <span class="firstOverlayLine"></span>
   <span class="secondOverlayLine"></span>
   <span class="thirdOverlayLine"></span>
   <img src="http://placehold.it/465x346">
</div>
