Had the HTML body set with absurdly huge margins. Now we have
much more space to work with. I also lengthened the button
names so that they hopefully make more sense, now that we have
more space to work with.
Now using <input type="number" pattern="\d*" step="1"> so that
the text field will pop up the numeric keyboard on both iOS and
Android. However this makes the "size=<blah>" no longer function.
So we set a fixed size for all <input type="number"> text fields
using CSS. Kinda hackish, but it works.
