Would it be possible to filter (strip out) the CSS elements 'position' and 'overflow' from pages when they are entered by a user (if possible, allow the function for sysops) on en.wikipedia? There has been a spate of disruption recently at the Reference desks whereby vandals edit either the main page, or templates transcluded on to that page, and insert CSS code such as:
<div style="position:fixed; width=20000; height=2000; left:9%; top:0%; overflow:visible;">
followed by an image and/or text, causing that image/text to obscure the rest of the page. As the tabs are obscured, less tech-savvy users cannot access the page history easily to revert the vandalism.
