Replace   with appropriate CSS.

A number of the components in this repo use   to create space in HTML.

- Callout.js
- Textarea.js
- DatePick.js
- TermsOfUse.js
- Input.js

Generally, it's a better practice to use CSS to create whitespace like this instead of   as it is more flexible and easier to modify. I would like to eventually replace these with CSS when we have the time.

Start by inspecting Callout.js, Textarea.js, DatePick.js, TermsOfUse.js, and Input.js to identify each use of   and review the surrounding styling. Done means the components use appropriate CSS for the intended whitespace without changing their rendered layout.
