"this could also override any other third party CSS" --i don't think so, Nic, as you apply the "important" property to the 3rd-party css, not your site's css.
however, if the 3rd-party css does not use unique class or id names, to target JUST their candy, then applying the 'important' property the 3rd-party css might affect the rendering of the rest of your site.
