Codepen Mobile view question

I was checking to see ho good my personal portfolio looked on my I phone 5S. However I can seem to scroll down the my section part 2 or 3. Is this just not available as a code-pen future. Is it because my website is not touch responsive. How could I make it responsive to touch.

Here is the link to my code-pen just in case.

Try like this, go to Change view and change it to debug mode, open the link it generates with the debug mode in your iPhone.
