No, you can't open a webpage created with publisher.
Most webpages will look the same in every program/browser if the page is
created with standard codes. However, as you may know, most webpage
creators including IE, Dreamweaver, etc etc have different standards and
so pages won't look the same with different web browsers. Also,
brwowsers interpret standard codes differently. You can google for
various html and CSS standards and they will tell you all browsers
aren't the same!. The trick is to use latest browser but most users
don't!
