Read More plugin, works beautifully, solved my prob

This plugin is perfect for that long content. You don’t want to cut it short, and you definitely don’t want to force the next item(s) way down off the visitor’s screen. This plugin adds a “read more” button wherever you like; and when they click or tap it, the remainder of your article scrolls gracefully into view. And there is a “read less” button that can be used to hide it again. Simple and effective!

The free version works fine, but I went for the Pro version which allows more configuration and decoration of the buttons, and a whole raft of other effects. Had a question and Edmon responded very promptly and helpfully
