Range slider tweaks

+ Adding better inline-examples for range slider.

Also...

+ Adjusted the default canvas size of live examples to be more compact, so that horizontal and vertical scrollbars don't appear (which fits most examples.  To intentionally use a taller or wider canvas, use the `tall` and `wide` flags, i.e.  `@example wide`, `@example tall` or `@example tall wide`).

+ Removed `@example` tag from some code sections that are without a visual live example (as they are they appear broken, some visual elements should be added to make them useful as live examples).
