CSS + JavaScript Transition - help -

Question

I got a simple code here - for experiment. I've tried looking up transition CSS and JavaScript, but I never got the result I wanted.
So, on this code what I'm trying to do is to make the 'JavaScript learning' content width to 10. And that's all done with CSS + JavaScript for applying Onclick.

Since you have used the ID tag. It is for us to simplify this point of the code.

To select the element simply write the name of its identifier, "elem";
Your "content"!
