I am new and I have a problem. I create site with Dreamwever. I use some layers in my layout.The primary browser is IE and everything is ok there. but in Firefox those layers change their position. How can I prevent it?
make sure you always have validated code see W3.org validator or firefox webdeveloper toolbar if all code fully validated incl CSS - then only smallest difference in display if any at all between IE and ffx
W3 validator doesn't always help though. It's more of a cross browser compatibility issue in some cases.
It is very strange but validator shows very many mistakes in the code despite the page was created with Dreamweaver.
Creating a page in DW doesn't necessarily mean it will validate. Try creating it in FrongPage or even worse, in MS Word
what clive said is valid for most tools out there with frontpage certainly being the worst of worst. the only professional tool to create cleanest possible output is Quanta Plus - but for Linux only. If using fully validated code - there might be a very few options less to use in web design but the cross platform/browser compatibility of validated code is nearly perfect with a few exceptions with known work arounds.
I mean I don't write code manually (only some editing). The sofrware generates it. So Dreamwever can create an invalid code?
