出于测试目的，我正在研究一种解决方案，该解决方案将使我仅使用一个按钮即可显示和隐藏特定的div（基于id）。

代码看起来像这样：
CSS
body {
font-family:'Trebuchet MS', sans-serif;
font-size:0.5em;
text-align:center;
}
.container {
padding:1em;
margin:0 auto;
background:#efefef;
}
#added-value-1 {
display:none;
}
#added-value-1:target {
display:block;
}
#expand-btn-1 {
margin:2em auto;
text-align:center;
padding:1em 2em;
font-weight:bold;
background:orange;
display:inline-block;
}
HTML
<div class="container">
<h1>
Container for testing purposes. Below content will show/hide upon button click
</h1>
<p id="added-value-1">

Quisque eleifend finibus ante, tincidunt varius nibh tristique id. In suscipit sit amet leo non vulputate. Maecenas eu tellus maximus, hendrerit augue ac, consectetur tortor.

Proin ullamcorper gravida odio et vulputate. Quisque eleifend finibus ante, tincidunt varius nibh tristique id. In suscipit sit amet leo non vulputate.

</p>
</div>
<a href="#added-value-1" id="expand-btn-1" title="Expand">Expand</a>
如果我错了，请纠正我，但是如果没有jquery和使用一个按钮，可能无法实现它？因为只有一个锚？
这可能有帮助
.details,
.show,
.hide:target {
display: none;
}
.hide:target + .show,
.hide:target ~ .details {
display: block;
}<div>
<a id="hide1" href="#hide1" class="hide">+ Expand</a>
<a id="show1" href="#show1" class="show">- Expand</a>
<div class="details">
Content goes here.
</div>
</div>这是只能用HTML和CSS完成的一种方法。
body {
font-family: sans-serif;
}
.accordion {
position: relative;
}
.accordion .accordion-content {
display: none;
}
.accordion input[type="checkbox"] {
position: absolute;

}
.accordion .toggle-btn {

border-radius: 4px;
display: inline-block;
background-color: #000;
}
.accordion input[type="checkbox"]:checked ~ .accordion-content {
display: block;
}<!DOCTYPE html>

<title>Page Title</title>
</head>
<body>
<div class="accordion">
<input type="checkbox" id="toggle" name="toggle">
<label class="toggle-btn" for="toggle">Toggle</label>
<p class="accordion-content">Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.</p>
</div>
</body>
</html>请让我知道是否有帮助。
