Hello all, I will submit later (probably next week) these 2 testcases (hopefully along with others on vertical-align and line-height): CSS Test: 'vertical-align: text-bottom' - line-height http://www.gtalbot.org/BrowserBugsSection/css21testsuite/vertical-align-117a.html (draft for now) CSS Test: 'vertical-align: text-top' - line-height http://www.gtalbot.org/BrowserBugsSection/css21testsuite/vertical-align-118a.html (draft for now) Right now, Firefox 7.0.1, Opera 11.52, Chrome 14.0.835.202, Safari 5.1.1 and Konqueror 4.7.2 pass these vertical-align-11[7|8]a testcases while IE8 and IE9 fail. As always, I welcome feedback, comments. regards, Gérard -- Contributions to the CSS 2.1 test suite: http://www.gtalbot.org/BrowserBugsSection/css21testsuite/ CSS 2.1 Test suite RC6, March 23rd 2011: http://test.csswg.org/suites/css2.1/20110323/html4/toc.html CSS 2.1 test suite harness: http://test.csswg.org/harness/ Contributing to to CSS 2.1 test suite: http://www.gtalbot.org/BrowserBugsSection/css21testsuite/web-authors-contributions-css21-testsuite.html
