Hey guys why does my mobile look like the way it does

well someone helped me but now my function does not work anymore. here is the new link

Your line:

  var checkString = document.getElementById("#quoteDisp").textContent;

There is no need for the “#” - you’re already getting by ID.

Just as a basic debugging skill, you really should have noticed this:

pen.js:12 Uncaught TypeError: Cannot read property 'textContent' of null
    at random (VM119 pen.js:12)
    at HTMLButtonElement.onclick (index.html?editors=1010:147)

in your browser console. The browser console (ctrl-shft-j, or something like that) is the best tool you have.
