This text is hidden until the summary line is clicked.

 

This is done using

<details><summary> This is displayed</summary>this is hidden until the summary is clicked</details>

So easy and impressive isn’t it. You used to have to set up scripts etc to do this. Now it is built in. Of course,  you’ll need to format the summary so it looks clickable.  

Note: Another technique, the accordion, requires a java script for it to work. <details… works without java script.

You can also have hover test using <span title = “hovertext”>displayed text</span>.
