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)
