This makes them keyboard-accessible. For mouse users, the only change
here is that the focus outline will remain on the button once clicked
(in future, this can be solved with :focus-ring, but for now this would
require a polyfill). the tooltip is explicitly hidden on `mouseleave`,
so even though the `<button>` retains focus after clicking, the tooltip
won't stay visible once mouse user moves away.
the mouse hover styles have explicitly not been make to also apply to
:focus, so as to minimise the visual impact for
mouse users (though the tooltip remains visible)
- but due to the default outline and the custom tooltip, it
should be fairly clear when keyboard users set focus to a copy button
too.
* Drop -x and -y as they're all the same
- Also move -width to elsewhere in the vars because it makes no sense by spacers.
- Update values of -x and -y across main Sass and docs Sass.
* Update docs to reflect changes; link to spacing utils from options page
On small screens (< 576px), all documentation pages containing
`.bd-example` styled tags, show the horizontal scrollbar because of a
wrong horizontal margin property.
This PR sets the horizontal margin on gutter width basis instead of rem.
Double up :hover styles to also apply on :focus (particularly the
masthead button needs this, as otherwise it gives no visible indication
of being focused)

* Clean up _flex.scss a little
This commit just cleans up the formating of _flex.scss by changing
it so that it uses a single `@include media-breakpoint-up` instead
of multiple. It also aligns all of the CSS properties so it looks
a bit nicer.
* Remove `-xs` from flex classes
- Creates new flexbox grid Sass file in our docs assets
- Updates the Gruntfile to compile said new Sass file and minify the output
- Update notice on flexbox docs page for how it works
- Only enable compiled flexbox grid CSS in hosted docs site, not in dev (for easier and specific debugging of all flexbox features)
- Rename -height to -height-base to match other vars
- Drop use of -height across the board and rely on it to be inherited
- Adjust padding of .dropdown-header to account for different line-height of h6 heading element (this needs refactoring for variables and rems also)
