如何在从一个部分到另一个部分时使CSS手风琴自动关闭打开内容

Question

我有一把css手风琴，我需要在点击每个标题时自动关闭。 这样一次只能打开一个部分。 现在他们都保持开放。

HTML

<section class="ac-container">

  <div>
    <input id="ac-1" name="accordion-1" type="checkbox" />
    <label for="ac-1"> title 1</label>
    <article class="ac-small">
      <p>some content</p>
    </article>
  </div>
  <div>
    <input id="ac-2" name="accordion-1" type="checkbox" />
    <label for="ac-2">title 2</label>
    <article class="ac-small">
      <p>some content </p>
    </article>
  </div>
  <div>
    <input id="ac-3" name="accordion-1" type="checkbox" />
    <label for="ac-3">title 3</label>
    <article class="ac-small">
      <p>some content</p>
    </article>
  </div>

</section>

Answer 1

您只需要在input元素中进行更改：

type="checkbox"

至：

type="radio"

但是你应该注意到这一点，总是会打开一个标签。
