CSS 将图像压缩到容器中的媒体查询

Question

我被迫使用基于 table 的布局，并且需要使其响应。我正在努力处理图像：当图像宽度超过屏幕宽度时，它应该缩小以适合屏幕。在这里的几篇文章中，我发现 max-width 被推荐，但不知何故我没有让它工作。

这是我的代码：

.headerImg { max-width: 100%; }
@media (max-width: 600px) {        
    .mainTabWidth {width: 100%;}   
    .halfWitdth   {width:  50%;}
    .qWidth       {width:  25%;}
}
@media (min-width: 601px)  {        
    .mainTabWidth {width: 594px;}   
     .halfWidth    {width: 236px;}
     .qWidth       {width: 113px;}
}

  <body style="font-family: Arial;font-size: 12pt;margin:0px;">
      <table align="center" border="0" cellpadding="0" cellspacing="0"
      style="border-collapse: collapse;" class="mainTabWidth">
        <tbody>
        <tr>
        <td style="padding: 10px;">
    Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.

        </td>
        </tr>
          <tr>
            <td><img src="http://mbaas.de/wordle.png" class=
            "headerImg" /></td>
          </tr>
        </tbody>
      </table>
    </body>

我也设置了一个fiddle (full-screen here).

在这种情况下，更改 media queries 的顺序以及您的图片

是一种更好的方法

when the image-width exceeds the screen-width, it should shrink to fit on the screen.

这里是你需要做的：

将 table-layout:fixed 添加到您的 .mainTabWidth

.mainTabWidth {
  table-layout: fixed;
}
.headerImg {
  max-width: 100%;
}
@media (min-width: 601px) {
  .mainTabWidth {
    width: 594px;
  }
  .halfWidth {
    width: 236px;
  }
  .qWidth {
    width: 113px;
  }
}
@media (max-width: 600px) {
  .mainTabWidth {
    width: 100%;
  }
  .halfWitdth {
    width: 50%;
  }
  .qWidth {
    width: 25%;
  }
}

<body style="font-family: Arial;font-size: 12pt;margin:0px;">
  <table align="center" border="0" cellpadding="0" cellspacing="0" style="border-collapse: collapse;" class="mainTabWidth">
    <tbody>
      <tr>
        <td style="padding: 10px;">
          <img class="headerImg" src="http://lorempixel.com/1000/300" />
        </td>
      </tr>  
      <tr>
        <td style="padding: 10px;">This text is embedded in a cell of table-row where the table is styled with a media-query, in the width is >607px, the table should be 594px wide and on smaller screens (max-width: 600px), the table should fill the available space to a 100%. But
          if you resize and observe, you will see the contrary: on large screens, the table takes all space and on small screens it takes 594px - so it seems the wrong query is selected...??? Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed
          diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet. Lorem

      </tr>
    </tbody>
  </table>
</body>
