Safari will omit the right padding of an element in a floated container if that element has trailing whitespace. Workaround is to ensure any elements with padding have no whitespace before the closing tag.

Where padding-right was being ignored by Safari, display:inline-block solved the problem for me, with no adverse affects in other browsers. May work in most cases.
