Commit 2dfba7c edits the options files, so options.html uses bootstrap classes instead of inline styles, and formats things (indentation, mostly) to be consistent with other files in the repo.
Commit af925da changes the options.html file to use HTML5 forms, which works better with screen readers. I also used <p> tags which remove the need for manual formatting with line breaks (<br>).
Cool, thanks!
