`mediawiki.legacy/commonPrint.css` needs an overhaul on coding style:
[] Coding guidelines: align colors
[] Coding guidelines: put every selector of combined selectors on one line
[] Coding guidelines: use `border: 0` instead of `border: none` and put border shortcut structure into same order across selectors for better gzipping
[] CSSLint: proof and fix overqualified selectors
[] CSSLint: disable setting `margin` for inline elements
[] General: get rid of print style hacks f. IE6&7?
[] General: give images `max-width: 100%` to stop them bleeding over the edge.
[] General: join pagination and 'Generic HTML elements'' rules
[] General: swap `1px` border values with `1pt`
[] General: add `word-wrap: break-word` to `pre, .mw-code` selector to aggressively wrap long words instead of going out of paper on those white space saved elements
[] General: add universal selector with `filter` and `text-shadow` resets to speed up printing.
