Hello, The following comments are with regards to this (draft for now) test: http://www.gtalbot.org/BrowserBugsSection/CSS3Multi-Columns/columns-shorthand-003.xht and a bit in conjunction with the spec. Such test uses vendor-prefix as needed to give all browsers the same test conditions. 1- " setting both the width and number of columns rarely makes sense. " http://www.w3.org/TR/css3-multicol/#introduction Yes. But I would expect an important minority of web authors using multi-column to be setting both the width of column and the number of columns. Generally speaking, web authors are pixel-perfect-controlling "freaks". 2- (21) W := ((available-width + column-gap) / N) - column-gap; http://www.w3.org/TR/css3-multicol/#pseudo-algorithm This (available-width + column-gap) / N division calculation can return a fractional value. 3- If you load the test and then increase text size with [Ctrl]+[+] key, you will see different renderings in browsers. After a text size increase with with [Ctrl]+[+] keys, - I would expect the number of columns to diminish and - I would NOT expect an horizontal scrollbar to be generated. Opera 12.16 and Chrome 28.0.1500.71 do not do that: the number of columns does not diminish and an horizontal scrollbar is generated when text size is increased. Firefox 22 reduces the number of columns and does not generate an horizontal scrollbar when text size is increased. The reverse is also worth considering. After a text size decrease with [Ctrl]+[-] keys, I would expect the number of columns to increase: Firefox 22 does that but not Opera 12.15 and not Chrome 29.0.1500.71.
