I was going to reply earlier with the meta I use, which is: <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> This does what Philippe describes as well as utilize Chrome Frame if the user has it installed.

For _new_ documents, you should always push IE to display in the latest mode (that it supports): <meta http-equiv="X-UA-Compatible" content="IE=edge"> Then test in older versions and add some adjustments as needed (i.e.via conditional comments). > If we changed this to: > > <!DOCTYPE html> > <html> > > > How would this affect what IE7 and IE8 render our pages? With the HTML5 doctype, IE 6 and up will all render in 'strict' mode, or their understanding of it…; there are some differences with what you use now (strict vs transitional). But as noted above, adjust for older browsers if needed. Philippe -- Philippe Wittenbergh http://l-c-n.co m Thanks Phillipe and Tom. I read about using edge in the meta tag but in a number of places I found that it is recommended that edge be used for testing, not production. So, why not use: <meta http-equiv="X-UA-Compatible" content="IE=7,8,9,10" /> ? I realize that would mean we would have to update the tag whenever a new IE version comes out but it only appears once, in our head include. Also, I ran some stats on which IE browsers our users use and it was encouraging: IE9=13%, IE8=9.6%, IE7=1.5%, and wonderfully IE6=.1%. ______________________________________________________________________ css-discuss [css-d@lists.css-discuss.org] http://www.css-discuss.org/mailman/listinfo/css-d List wiki/FAQ -- http://css-discuss.incutio.com/ List policies -- http://css-discuss.org/policies.html Supported by evolt.org -- http://www.evolt.org/help_support_evolt/
