I have a text that I am loading from the database, but it is very long so I was thinking about doing an effect in JavaScript to read more, (or less). I hunted for information about it but they show it with two < div > and it's not exactly what I need. I hope you can help me
If it helps, I'll give you an example of how you could do it with Bootstrap (Jquery already implied)
