我目前有一个表格设置，可以将图像保存在不同大小的表格中，并且可以相应地调整图像大小。如何使图像保持纵横比？

如何在调整窗口大小时使图像保持4：3的比例？

1 个答案:

答案 0 :(得分：1)

将<img>高度更改为auto有效。 https://jsfiddle.net/JustusFT/3qtb1r9v/

但是，我建议您使用bootstrap之类的网格系统，而不是使用表格。

HTML：

<div class="page-wrap">
  <header>
    <h1>
                    <a href = "main.html"> Homeless Helpers</a>
                </h1>
    <table class="headerTable" , width="100%">
      <tr>
        <th width="20%">
          <p class="headerP">
            <a href="message.html">Message</a>
          </p>
        </th>
        <th width="20%">
          <p class="headerP">
            <a href="life.html">Goal</a>
          </p>
        </th>
        <th width="20%">
          <p class="headerP">
            <a href="videos.html">Testimonials</a>
