My answer box and preview box were side by side, but I hit a key on the computer accidentally, and now the preview box is below the answer box, which makes it a lot more difficult to check my work as I go along. Can somebody tell me how to change it back?

One way this can happen is by changing the zoom. I use Chromes, and if I change the zoom to 90%, I get the same thing.

There may be other ways it can happen, but check your zoom.

I think Jim's right, you could have accidentally hit CTRL and - (control and minus), which is zoom out in Chrome.

To get it back to 100% you can hit CTRL and +. Or hold dwon CTRL and use the scroll on your mouse- scroll up is zoom in and scroll down is zoom out.

I don't know if any of this is helpful, but here's a link to Chrome's Help Page on this:
