You could use Quanta +. Pressing 2 will load the page you just edited in Opera;
Ctr+Shift+F12 in Firefox, F12 in Konqueror; Mozilla in Shift+F12; Netscape in Shift+F6;
OTOH, you should always be aware that what the end user sees, depends heavily on
his/her settings. Do never expect your page to look exactly the same as on your system.

"The Web Design Group was founded to promote the creation of non-browser specific, non-resolution specific, creative and informative sites that are accessible to all users worldwide. To this end, the WDG offers material on a wide range of HTML related topics. We hope that with this site as a reference, you will be able to create Web sites that can be used by every person on the Internet, regardless of browser, platform, or settings."
