Define a default size in em, equal to the number of characters in the +" input element, in case javascript is disabled and the browser does not +" support the 'ch' unit. Unfortunately this makes Opera no longer work +" properly without javascript. 1em per character is much too wide but it +" looks better in webkit browsers than unaligned columns. +" 2. Insert the following javascript to run at page load, which checks for the +" width of a single character (in an extraneous page element inserted +" before the page title, and set to hidden) and compares it to the width of +" another extra <input> element with only one character. If the width +" matches, the script does nothing more, but if not, it will figure out the +" fraction of an em unit which would correspond with a ch unit if there +" were one, and set the containing element (<pre> or <div>) to a class with +" pre-defined rules which is closest to that fraction of an em.
