How are the automatic list columns created?
Fragment of a discussion from Extension talk:Cite
this is done by utilizing a CSS3 (or is it css2?) feature called "columns". not all wikis choose to use this feature, and those that do are doing it through their css (look for "-moz-column-width", "-moz-column-count", "-webkit-column-width" or "-webkit-column-count"). it is also somewhat important to note that not all browsers support this feature - notably IE doesn't.
