Formatting updates to form (plus a couple of fixes).

Improvement

We have updated how some fields appear in forms. Changes include:

• All labels are now bolder to help them stand out. We've also made them a little lighter to help lessen the visual fatigue of long, bold labels.
• We've moved the “prompt” for checkbox fields above the options, it used to appear below where it was difficult to associate it with the correct field.
• We've increased the spacing between multiple-option fields to make them easier to press on touch-based devices.

We've also fixed:

• An issue where prompts were not appearing correctly on some ‘radio button’ fields.
• An issue where radio buttons would not be selected correctly when clicking on the label, this occurred when when multiple options had the same label.
