How to hide text in Markdown behind a button.


Example:

%%hidden(Button text):
Hidden text goes here.
%%

%%hidden(Button text): Hidden text goes here. %%

You can use this for hiding problem answers and asking the user to solve the problem themselves before clicking the button to see the correct answer.
