Clean up example-input

[anselmbradford]

There are example-input classes that appear to have no styles attached to them.

There are also example-input__full classes that do have styles, but these are coded to be elements of a parent example-input, which they are not.

I'd suggest removing the existing example-input entries, and renaming the example-input__full entries to example-input.

Additionally, advanced__tips should be updated to advanced-tips if it's not an element.
