Question

已解决

请参阅下面代码段中的工作代码。能用者免费使用。

说明：有一个包含 10 "See more/less" 个部分的包装器。所有 11 个都可以折叠和关闭。按钮有悬停效果。文字均为英文。没有 Javascript 或 jQuery。纯CSS/HTML溶液。

如果您不需要全部十个，只需将它们从 HTML 中删除即可。无需将它们从 CSS.

中删除

由于包装纸很长，我在折叠的底部添加了一个按钮。所有部分均由水平标尺分隔。

兼容于：

文本元素<p>
图片<img>
Iframes <iframe>
服务器端包括

问题

~~我正在尝试创建一个二级 "Read More/Read Less"。~~

~~第一层应该hide/show，包裹的图片、视频、文字等信息量较大。此信息将拆分为各自的 "Read More/Read Less" 部分，包装内总共最多 10 个部分。~~

~~但是我很难创建作为包装器一部分的第二级。我相信可以这样做，但我真的做不到。~~

<p>What is Lorem Ipsum? 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>

<p>It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>

<h3>Why do we use it?</h3>
<p>It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English.</p>

<p>Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy.

<h1>Where does it come from?</h1>
<p>Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source.</p>

<p>Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.</p>
