html - 列表项下的样式跨度类

Question

我们如何在 css 中为列表项下的 span 类设置样式？

我试过如下，但它不工作

wrap.error {
  color: #FF0000;
  display: block;
}

<ol>
  <li>
    <span class='error'>Some error</span>
  </li>
</ol>

Answer 1

像这样

li span.error {
    color:#FF0000;
    display:block;
}

检查片段

li span.error {
   color:#FF0000;
   display:block;
}

<ol>
    <li>
      <span class='error'>something here</span>
      <h3>What is the smallest prime number?</h3>
      <input type="radio" name="question0" value="A"<?php echo ($question0=='A')? 'checked':''; ?> />2<br>
      <input type="radio" name="question0" value="B"<?php echo ($question0=='B')? 'checked':''; ?> />1<br>
      <input type="radio" name="question0" value="C"<?php echo ($question0=='C')? 'checked':''; ?> />3<br>
      <input type="radio" name="question0" value="D"<?php echo ($question0=='D')? 'checked':''; ?> />4<br>
    </li>
</ol>
