Thank you Georg and Roger for your help. I have incorporated your recommendations into http://www.availcompany.com/webdev/webcode/css_test4.htm as follows: 1. Per Georg added: * html div#column2 {height: 100%;} * html div#column2 table {float: left; margin-right: -10px;} 2. per Gerog and Roger, Removed the clearing-div, and added #footer {clear: both;}. Do you still think I do not need .clearfix even though threecolwrap wraps three left floated columns? 3. Per Georg, I am reading about 'em resizing bug'[1] in IE/win.

The short answer: IE/win has calculation-bugs. 100% isn't always 100%. The quick solution, add... * html div#column2 {height: 100%;} * html div#column2 table {float: left; margin-right: -10px;} ....which will provide some space for IE to put its bugs without messing up the layout. > Question 2: why is <div style = "clear:both;"></div> required above > footer div markup for footer to clear the three columns despite using > "no-extra-markup" clearing method .clearme class on the > threecolwrap? It isn't. Remove the clearing-div, and add... #footer {clear: both;} --- Note: you should also add... html {font-size: 100%;} ....to avoid the 'em resizing bug'[1] in IE/win. regards Georg [1]http://www.gunlaug.no/contents/wd_additions_13.html -- http://www.gunlaug.no ______________________________________________________________________ css-discuss [EMAIL-REMOVED]] http://www.css-discuss.org/mailman/listinfo/css-d IE7b2 testing hub -- http://css-discuss.incutio.com/?page=IE7 List wiki/FAQ -- http://css-discuss.incutio.com/ Supported by evolt.org -- http://www.evolt.org/help_support_evolt/ ______________________________________________________________________ css-discuss [EMAIL-REMOVED]] http://www.css-discuss.org/mailman/listinfo/css-d IE7b2 testing hub -- http://css-discuss.incutio.com/?page=IE7 List wiki/FAQ -- http://css-discuss.incutio.com/ Supported by evolt.org -- http://www.evolt.org/help_support_evolt/
