如何让 html 图像具有响应性?

我有一个 html 图像。这是我的徽标,右上角是社交媒体的链接。 我已经将图像放到位,但当我调整屏幕大小时,它不像其他东西一样响应。

这就是我所拥有的;

<div id="headerhj" align="center">
  <table style="display: inline-table;" border="0" cellpadding="0" cellspacing="0" max-width="100%">
    <!-- fwtable fwsrc="header html.fw.png" fwpage="Page 1" fwbase="main.jpg" fwstyle="Dreamweaver" fwdocid = "2088656467" fwnested="0" -->
    <tr>
      <td><img src="img/htm/spacer.gif" alt="" name="undefined_2" width="815" height="1" /></td>
      <td><img src="img/htm/spacer.gif" alt="" name="undefined_2" width="25" height="1" /></td>
      <td><img src="img/htm/spacer.gif" alt="" name="undefined_2" width="6" height="1" /></td>
      <td><img src="img/htm/spacer.gif" alt="" name="undefined_2" width="24" height="1" /></td>
      <td><img src="img/htm/spacer.gif" alt="" name="undefined_2" width="1" height="1" /></td>
    </tr>
    <tr>
      <td rowspan="2"><img src="img/htm/main_r1_c1.jpg" alt="" name="main_r1_c1" width="815" height="171" id="main_r1_c1" align="middle" /></td>
      <td><a href="www.facebook.com"><img name="main_r1_c2" src="img/htm/main_r1_c2.jpg" width="25" height="24" id="main_r1_c2" alt="" /></a></td>
      <td rowspan="2"><img name="main_r1_c3" src="img/htm/main_r1_c3.jpg" width="6" height="171" id="main_r1_c3" alt="" /></td>
      <td><a href="www.twitter.com"><img name="main_r1_c4" src="img/htm/main_r1_c4.jpg" width="24" height="24" id="main_r1_c4" alt="" /></a></td>
      <td><img src="img/htm/spacer.gif" alt="" name="undefined_2" width="1" height="24" /></td>
    </tr>
    <tr>
      <td><img name="main_r2_c2" src="img/htm/main_r2_c2.jpg" width="25" height="147" id="main_r2_c2" alt="" /></td>
      <td><img name="main_r2_c4" src="img/htm/main_r2_c4.jpg" width="24" height="147" id="main_r2_c4" alt="" /></td>
      <td><img src="img/htm/spacer.gif" alt="" name="undefined_2" width="1" height="147" /></td>
    </tr>
  </table>
</headerhj>

请问我哪里做错了?

在您的 css 文件中添加此代码:

img {
    width: 100%;
    height: auto;
}

这将影响所有 img 元素。 更具体地说,您可以使用特定的 id,例如:

#headerhj img {
    width: 100%;
    height: auto;
}

例如,您必须使用带有 <style> 标签或内联 <img style="width:100%"> 的 CSS

It looks like you're hardcoding the <img> widths and heights, so they won't respond, as they aren't driven by percentages of the containing <td>

通常,为了使用百分比,父容器必须具有硬编码值,即使它是其他值的百分比,也不确定此原则如何应用于表格

查看 min-width max-widthwidth 以及百分比和 auto
