html - 单击关闭 Accordion 选项卡

Question

我有一些非常基本的 Accordion 选项卡，单击时打开，单击另一个时关闭。我希望它们也能够在您单击打开的选项卡时关闭。有谁知道如何做到这一点？

.ac-container {
    // max-width: 400px;
}

.ac-container label {
    // height: 30px !important;
    line-height: 21px !important;
    // font-size: 12px !important;
    padding: 5px 20px;
    text-transform: uppercase;
    font-weight: 100;
    position: relative;
    z-index: 20;
    display: block;
    height: 30px;
    cursor: pointer;

    height: auto;
    line-height: 20px;
}
.ac-container span {
  position:absolute;
  bottom:5px;
  right:8px;
}
.ac-container {
    width: 100%;
    // margin: 10px auto 30px auto;
    text-align: left;
}

.ac-container label:hover {

Now we took an oath, that I'm breaking now. We said we'd say it was the snow that killed the other two, but it wasn't. Nature is lethal but it doesn't hold a candle to man. </p>

您的代码无效。
您的 HTML 没有 H4 标签。

这是一个可以按您想要的方式工作的工作示例。

$(document).ready(function() {
  $('.accordion-title').click(function() {
    if ($(this).hasClass('active')) {
      $(this).removeClass('active').next('.accordion-content').slideUp();
    } else {
      $('.accordion-title').removeClass('active');
      $('.accordion-content').slideUp();
      $(this).addClass('active').next('.accordion-content').slideDown();
    }
  });
});

.accordion-title {
  font-size: 14px;
  font-weight: bold;
  border: 1px solid black;
}

.accordion-content {
  border: 1px solid black;
  display: none;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="accordion-title">Title</div>
<div class="accordion-content">Content</div>
<div class="accordion-title">Title 2</div>
<div class="accordion-content">Content 2</div>
<div class="accordion-title">Title 3</div>
<div class="accordion-content">Content 3</div>
