Why not use the "Composer" component of the Mozilla Suite? Much more standardized than anything MS has to offer. There is a css plugin I believe.
The Mozilla Suite (still available) is now being developed under the name 'Seamonkey".
Maybe visit w3c.org or
http://www.w3schools.com to learn how to write standards compliant pages.
Not much for the flash stuff, dont have it installed, dont want it installed. If your site looses functionality without flash, you have a problem. Aparently 'svg' graphics is the upcoming 'open standards' competitor to flash.
