无法使光标指针在悬停时显示

Question

在onclick函数中，当我将鼠标滚动到"阅读更多"文本上时，它不会显示光标，因此您知道它是可点击的。我已经可以用cursor:pointer通过css来完成这项工作，但我遇到的问题是，在第一次点击页面后，我的所有元素只有在双击阅读更多时才会打开。第一次单击任何元素时，只需单击一次即可打开，但当我转到下一个元素并单击时，需要单击两次。我很感激能得到的任何帮助。感谢

试试这个：https://jsfiddle.net/7rdqg38m/2/这个解决方案确实需要jQuery和CSS。这允许您使用toggleClass制作一个真正干净优雅的函数，当然也允许您避免内联样式

index.html:

<span id="dots" class="hidden"></span>
