What I'm looking for is a way to have a consistent em based measuring unit across all block elements in a site so that a width of say 10em will be the same no matter what the font size of the text in that block is.
Here's a little demo using your example with each element given a left margin of 10em, and similar headers with my typical use of spans: http://hurricane.mit.edu/erp_manuals/test.html As you can see the way you're suggesting still gives an effective margin of 12em when the font size is 1.2em and 15em when the font size is 1.5em. -- Bill McAvinney Massachusetts Institute of Technology Web Services Administrative Computing, IS&T 617-258-6023 ***************************************************** The discussion list for http://webstandardsgroup.org/ See http://webstandardsgroup.org/mail/guidelines.cfm for some hints on posting to the list & getting help *****************************************************
