html - 选项卡模型第 4 个 child 未显示

Question

我正在研究这个选项卡模型，但遇到了一些问题。我刚刚浏览了选项卡模型，发现这很有趣。但我发现只有三个标签。因此，据我所知，我已经为第四个选项卡添加了代码，但它没有显示。旋转有一些错误计算。

<h4>Standard Accordion with A little styling</h4>

Answer 1

您错过了更改最后一项的类别。

现在:

<label class="tab" for="tab-bottom">BACK</label>

应该是:

<label class="tab" for="tab-back">BACK</label>
