Hello, " Calculation of the shrink-to-fit width is similar to calculating the width of a table cell using the automatic table layout algorithm. Roughly: calculate the preferred width by formatting the content without breaking lines other than where explicit line breaks occur, and also calculate the preferred minimum width, e.g., by trying all possible line breaks. CSS 2.1 does not define the exact algorithm. Thirdly, calculate the available width: this is found by solving for 'width' after setting 'left' (in case 1) or 'right' (in case 3) to 0. Then the shrink-to-fit width is: min(max(preferred minimum width, available width), preferred width). " CSS2.1, section 10.3.7 Absolutely positioned, non-replaced elements http://www.w3.org/TR/CSS21/visudet.html#abs-non-replaced-width Q1: Shouldn't an hyphen inside a string normally represent a possible line break opportunity? Q2: Besides a blank space, what else should represent or be considered as a normal line break opportunity? Q3: "CSS 2.1 does not define the exact algorithm." I wonder why. Will CSS 3 provide an exact algorithm? This is more about my curiosity than a formal question. Test ---- http://www.gtalbot.org/BrowserBugsSection/css21testsuite/shrink-to-fit-width-hyphenated-words.html Test results ------------ Konqueror 4.9.1 displays: abcde-fghi-jkl (computed width: 443px and computed height: 75px) Firefox 15.0.1 displays: abcde- fghi-jkl (computed width: 227px and computed height: 154px) IE10, Opera 12.02 and Chrome 21.0.1180.89 display: abcde- fghi- jkl (computed width: 216px and computed height: 225px-228px) IE8 and IE9 display: abcde -fghi- jkl which seems like a bug. I think IE10, Opera 12.02 and Chrome 21.0.1180.89 are rendering the test correctly. Am I wrong on this?
