HTML-纯 html 手风琴折叠其他.

Question

当 .content [type=checkbox]：选中时，我需要一个否定伪类来折叠扩展的内容。怎么说折叠除单击之外的所有列表？没有javascript可能吗？

.HTML：

<div class="accordion vertical">
    <ul>
        <li>
            <input type="checkbox" id="checkbox-1" name="checkbox-accordion" />
            <label for="checkbox-1">Title&nbsp;One</label>
            <div class="content">
                <h3></h3>
                <p></p>
            </div>
        </li>
        <li>
            <input type="checkbox" id="checkbox-2" name="checkbox-accordion" />
            <label for="checkbox-2">Title&nbsp;Two</label>
            <div class="content">
                <h3></h3>
                <p></p>
            </div>
        </li>
        <li>
            <input type="checkbox" id="checkbox-3" name="checkbox-accordion" />
            <label for="checkbox-3">Title&nbsp;Three</label>
            <div class="content">
                <h3></h3>
                <p></p>
            </div>
        </li>
        <li>
            <input type="checkbox" id="checkbox-4" name="checkbox-accordion" />
            <label for="checkbox-4">Title&nbsp;Four</label>
            <div class="content">
                <h3></h3>
                <p></p>
            </div>
        </li>
    </ul>
</div>

Answer 1

答案其实很简单，很容易实现，看这个JSFiddle

我所做的只是将（在您的 HTML 中）"复选框"一词替换为"radio"，然后对 CSS 进行了一个小编辑：

这是CSS中的最后一项，这需要是"单选"，而不是"复选框"

.vertical [type=radio]:checked ~ label ~ .content {
    height:300px;
    border:1px solid #542437;
}
