As we discussed in #7, it looks like this PR will make the labels disappear at small screen sizes.

I think that the labels are the most important part of the interface, or else users can't tell what they're tuning. And in the example of a checkbox field, the checkbox itself takes up very little space, so it makes sense to keep the left column intact rather than have a huge blank space in the right.

I'd vote for collapsing one of the interface elements in the right columns, such as the slider (for numerical values, the textbox is sometimes needed for precise adjustments), at small screen sizes, rather than lose the labels.
