纯 CSS 和 HTML 菜单（带有子菜单项和文本）

Question

我正在尝试创建一个纯 CSS/HTML 菜单（否 JAVASCRIPT），这是代码示例：https://jsfiddle.net/1Lrr4fme/1/.

目的是让帮助菜单在单击时显示文本。但是，我在导航如何调整 CSS 以允许每个跨度 open/close 独立于主要跨度时遇到了极大的困难。

我尝试了一些不同的东西，但我想我遗漏了一些东西。

Answer 1

您的问题是您对每个输入字段使用了相同的 ID。每个字段的 ID 应该是唯一的，以便您可以打开和关闭与该字段相关的文本。

您应该使用类在所有输入字段（例如突出显示和边框）中设置您想要的样式和行为，然后为每个字段设置不同的 ID。

示例html:

<article><input id="help_menu" role="button" type="checkbox" /> <label for="help_menu" class="checkbox_label" onclick=""><span>Show Help</span><span>Hide Help</span></label>
<section>


<article><input id="new_contract" role="button" type="checkbox" /> <label for="new_contract" class="checkbox_label" onclick=""><span>1. Entering New Contracts</span><span>Hide Help</span></label>
<section>
<p>hi</p>
</section>
</article>

<article><input id="contract_review" role="button" type="checkbox" /> <label for="contract_review" class="checkbox_label" onclick=""><span>2. Completing a Contract Review</span><span>Hide Help</span></label>
<section>
<p>hi</p>
</section>
</article>

<article><input id="terminate_contract" role="button" type="checkbox" /> <label for="terminate_contract" class="checkbox_label" onclick=""><span>3. Terminating Contracts</span><span>Hide Help</span></label>
<section>
<p>hi</p>
</section>
</article>

<article><input id="contract_dates" role="button" type="checkbox" /> <label for="contract_dates" class="checkbox_label" onclick=""><span>4. Calculated Contract Dates</span><span>Hide Help</span></label>
<section>
<p>hi</p>
