多个CSS在同一页面中折叠/展开

Question

我的CSS崩溃/扩展代码来自@ https://codepen.io/peternguyen/pen/hICga/。但我的代码的问题是它们不能在同一页面中工作。我打算在Wordpress页面上使用它。看看我的代码。谢谢。

input {
    display: none;
    visibility: hidden;
}

label {
    font-weight: bold;
    font-size: 15px;
    display: block;
    color: #666;
    text-decoration: underline;
}

label:hover {
    color: #000;
}

#expand {
    height: 0px;
    overflow: hidden;
    transition: height 0.5s;
    color: #000;
}

section {
    padding: 0 20px;
}

#toggle:checked ~ #expand {
    height: auto;
}

<input id="toggle" type="checkbox">
<label for="toggle">Hidden Kitten</label>
<div id="expand">
    <section>
        <p>mew</p>
    </section>
</div>
<input id="toggle" type="checkbox">
<label for="toggle">Hidden Kitten</label>
<div id="expand">
    <section>
        <p>mew</p>
    </section>
</div>

Answer 1

我使所有id特定的部分独立，并将~更改为+。
