javascript - 如何为文本提供 readmore？

Question

我在 p 标签中有一段很长的文字。

        <p> type and scrambled it to make a type specimen book. 
        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>

如果文本大于 100 个字符(例如在 whatsapp 中)，我想显示一个阅读更多链接。如何实现？我是否可以通过 pur css 来完成？还是需要js？它应该在 readmore 和 readless 之间切换。
