当用户向下滚动页面时，试图让类保持粘性并且不断地在视图中，但无论如何都不会起作用。
我累了：
.entry-summary{
position: -webkit-sticky; /* Safari */
position: sticky;
top: 0;}
但这没有任何作用。
完整的代码可以在下面看到，并且是这个网页https://aqwaa.net/product/constriction/的一部分：
<div class="qode-single-product-summary">
<div class="summary entry-summary">
<div class="clearfix">

<p><strong>Mental Health Description: </strong>So often a symptom of anxiety is the feeling of a tightness or tension in the rib cage area. Anxiety has the ability to kick start your bodies fight or flight response, which can increase your stress which often leads to your bodies muscles to contract and tighten, hence, the ribcage tightness symptom. This piece is designed to bring awareness to how it feels inside for someone who is suffering with mental health problems.</p>

我希望类.summary.entry-summary在用户向下滚动页面时保持可见，这不会发生。
根据您的代码片段，看起来好像.entry-summary类属于一个div，它是容器中的单个子元素。
position：sticky只允许子进程“浮动”在同一容器中的兄弟元素上。
我将你的代码复制到codepen中，并在你的<div>中添加了另一个空白的<div class="qode-single-product-summary">来占用一些垂直空间并提供一个兄弟元素，它似乎工作得很好。
（查看我的评论“我在你的代码底部添加了这个”）另外如果你运行我提供的代码片段，你应该看到粘性属性工作，直到大约一半时我添加的虚拟div结束...
