Question

我需要在图像表上添加叠加标签，这些图像每次都随机混洗，但每个图像角上总会有位置编号。如何使用HTML添加？看一下样本：

这是我的表格代码，我应该添加什么来在我的图片上添加标签？

<table id="userArrayTable" >
<tr id="trHeader">
<td id="td">1</td> <td id="td">2</td> <td id="td">3</td> <td id="td">4</td>
</tr>
<tr>
<td><img src="images/foodicons/food-1.jpg" width="50" height="50"/></td> <td><img src="images/foodicons/food-2.jpg" width="50" height="50"/></td> <td><img src="images/foodicons/food-3.jpg" width="50" height="50"/></td> <td><img src="images/foodicons/food-4.jpg" width="50" height="50"/></td> 
</tr>

<tr id="tr2">
<td><img src="images/fruitsicons/fruites-1.jpg" width="50" height="50"/></td> <td><img src="images/fruitsicons/fruites-2.jpg" width="50" height="50"/></td> <td><img src="images/fruitsicons/fruites-3.jpg" width="50" height="50"/></td> <td><img src="images/fruitsicons/fruites-4.jpg" width="50" height="50"/></td>  
</tr>

<tr>
<td><img src="images/animalsicons/animal-1.jpg" width="50" height="50"/></td> <td><img src="images/animalsicons/animal-2.jpg" width="50" height="50"/></td> <td><img src="images/animalsicons/animal-3.jpg" width="50" height="50"/></td> <td><img src="images/animalsicons/animal-4.jpg" width="50" height="50"/></td>   
</tr>

<tr id="tr4">
<td><img src="images/jobsicons/job-1.jpg" width="50" height="50"/></td> <td><img src="images/jobsicons/job-2.jpg" width="50" height="50"/></td> <td><img src="images/jobsicons/job-3.jpg" width="50" height="50"/></td> <td><img src="images/jobsicons/job-4.jpg" width="50" height="50"/></td>

Answer 1

您可以在每个span之后添加img元素，并将其设置为img的顶部，如下所示：

＆＃13;

#userArrayTable td {
  position:relative;
}
#userArrayTable span {
  position:absolute;
  right:10px;
  bottom:10px;
  z-index:10;
  padding:10px 15px;
  border-radius:50%;
  background:purple;
  color:white;
  font-size:1.5em;
}

＆＃13;

<table id="userArrayTable">
  <tr id="trHeader">
    <td id="td">1</td>
    <td id="td">2</td>
  </tr>
  <tr>
    <td>
      <img src="http://placekitten.com/200/200"/>
      <span>A</span>
    </td>
    <td>
      <img src="http://placekitten.com/200/200"/>
      <span>B</span>
    </td>
  </tr>
  <tr id="tr2">
    <td>
      <img src="http://placekitten.com/200/200"/>
      <span>Z</span>
    </td>
    <td>
      <img src="http://placekitten.com/200/200"/>
      <span>X</span>
    </td>
  </tr>
</table>
