Equals 3 widths of an "M" in the selected font at the selected font size. Change the font or font size, and the size of the em changes proportionally. > 3pt 3/72" of an inch. An absolute measurement, although its precise size when rendered on screen by one browser/OS/display resolution combo may not come out exactly the same size as the rendering by a different browser/OS/display resolution combo. > This is normally used in setting margins.

The screen itself may vary in size: I have a 15" monitor here that can run 1280x1024 resolution, same as a lot of 17" LCD displays. If I measured 3 pts as displayed on each display, they wouldn't come out to the same size on the the display. Think of the screen as elastic paper. The resolution on a smaller display is the starting "paper" size. A larger display at the same resolution stretches the "paper" to fit its larger physical size. -- David [EMAIL PROTECTED] authenticity, honesty, community ______________________________________________________________________ css-discuss [EMAIL PROTECTED] 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/
