Thread:Project:Support desk/Possible to change the width of the wiki pages?/reply (5)

Please do not do what 79.143.33.66 suggested. This is not a supported way to style mediawiki and will break next time you upgrade. As subfader said above, there are certain special pages on a wiki where you can put css ( mediawiki:Common.css ) which is the recommended way to add custom styles to your wiki.
