after so many versions, i can't believe DreamweaverMX still can't get it right. i just did a webpage and when i went into preview browser, it looked different from what i saw. then when i uploaded the file, it looked different from BOTH preview and layout versions.
like is it just me or is Dreamweaver taking us webmasters/designers for a ride?
Layout and Preview are 2 entirely different entities and serve entirely different purposes. They're going to look different. And since preview is handled with an external browser and can be done in any browser, that adds yet even more opportunity for differences.
Looking different on the server compared to local is an odd one. Unless you are using a different browser for previews locally vs online. Dreamweaver wouldn't have anything to do with that phenomenon.
Dreamweaver isn't taking you for a ride, this can happen with even a page written with notepad. This is why it is essential to test on a variety of platforms, browsers and operating systems. You never know what can happen!
