html - 使键盘选项卡 Action 充当鼠标悬停

标签 html css tabs hover tabindex

我使用的是稍微修改过的版本:https://codepen.io/ferry/pen/ZYVwxz (谢谢迈克尔·费里)。

HTML:

    <div class="accordion">
  <ul>
    <li tabindex="0">

        <a href="#">
          <h2>Lorem Ipsum 1</h2>
          <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit</p>
        </a>
      </div>
    </li>
    <li tabindex="0">
      <div>
        <a href="#">

@media screen and (max-width: 600px) {

  .accordion {

    table-layout: fixed;
    width: 100%;
    -webkit-transition: none;
    transition: none;
  }
}
</style>

我无法在使用键盘时显示“幻灯片”。

我尝试添加 .active、:focus、role="button"、aria-expanded="true"和 tab-index 都无济于事。

在我秃顶之前，有没有人有解决办法？ (不使用 javascript)

非常感谢!

最佳答案

如果您使用 tabindex="1"在你的 li喜欢<li tabindex="1"> , 你应该能够用 :focus 来定位他们作为

li {
  &:focus {
    // your stuff here
  }
}

现在发生的事情是，当您按下 Tab 键时，它会选择 a。元素，但转换应用于 li .

如果我从 Michael Ferry 的代码笔中获取代码，您将得到以下几行代码。

在 SCSS 代码中我添加了 li:focus ~ li针对李的 sibling 和li:focus到现有代码以重现动画。

我还建议您禁用 a元素标签 tabindex=0为了避免用户在通过 slider 切换后再次滚动到顶部。
