I was looking at some HTML coding on a website and I saw that a lot of websites use these 3 dots (...) to hide bits of code between 2 <>'s.
Example: https://i.stack.imgur.com/Gpy9r.jpg
When you click on the dots, more code opens up and you can read what is inside of the 2 <>'s.
Example 2: https://i.stack.imgur.com/t2tYS.jpg
So my question is, how do I make this in my own code? Like if I have <> A LOT OF TEXT <>, how would I make the text inside the <>'s 3 dots and only visible when you click on them (to save space).
Thanks in advance!
