Requires FAR too many clicks. (Maybe make the focus and directrix draggable.
Or make the increments 0.5.)

"Wrong" answers can be so close that
there is no orange to be seen. (Larger
increments for both parabolas should
fix this. Or, accept small errors as
correct.)

Buttons should be fixed in one place so
that they don't jump around when the
width of the number changes.
