Comment (by rabmalin):

 I really like the idea. When developing theme, it is generally considered
 as plugin territory. But I like to take it as an essential theme
 component. I always implement this feature in all my themes.

 * We should absolutely sanitize the input. In theme I use
 `wp_filter_nohtml_kses()` or `wp_strip_all_tags()`. But problem arise when
 escaping. May be we need to devise special escaping function considering
 some possible characters like `'`, `"`.
 * I would go for custom control for `Custom CSS` so that we can have
 larger scope for advancement like syntax highlighting, linting, line
 numbers, etc in the future.
