Hi Michael, Here is another way of creating the 'Read more/less' component. This one does not use js at all and is maybe easier. This one also has two units that can be taken out of the holding container 'whole-page' and placed where needed. You just have to give the .wrapper different IDs. It uses the Pseudo Selector 'Target' to show and hide the paragraph text. To edit that text, remove the height of the container .wrapper temporarily by setting it to auto. Remember to set it back when done. The different height before and after the breakpoint is all it takes to make more of the text visible on wider screens.
The 'heavy lifting' (creating the thing)has been done by Frank Cook, and I have transferred it into an older SD version for you.
