So I was trying to make a button that upon clicking on it changes its style and upon clicking it again changes its style to the original one. I am very exhausted and my brain works on 10%, I feel deeply ashamed of myself for not being able to figure it out since I've already done it a couple of times. Sorry for the stupid question, I have been reading through google to see how to do it I used to do it on my own without searching for a method to do it and I know it's nothing complicated but I just don't know why my code doesn't work.............

</html>There are 2 mistakes here.
background as bacground in the second if statement.else if statement, otherwise it will always detect the second if statement as being correct because the first one sets it to "on".<!DOCTYPE html>
