" " The problem is that without the 'ch' unit, it is not possible to specify a " size of an <input> in terms of character widths. Only Opera seems to do the " "sensible" thing and make the <input> sized to fit exactly as many characters " as specified by its "size" attribute, but the spec actually says "at least " wide enough to fit 'size' characters", so the other browsers are technically " correct as well. " " Anyway, this leads to two diffculties: " 1. The foldcolumn is made up of multiple elements side-by-side with " different sizes, each of which has their own extra padding added. Thus, a " column made up of one item of size 1 and another of size 2 would not " necessarily be equal in size to another line's foldcolumn with a single " item of size 3. " 2. The extra padding added to the <input> elements adds up to make the " foldcolumn and line number column too wide, especially in Webkit " browsers. " " So, the full workaround is: " 1. 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.
