When I validate my site with Dreamweaver CS3, I get no errors. Yet, when I validate using this site: http://validator.w3.org/check?uri=www.srdar.org&charset=(detect+automatically)&doctype=Inl ine&group=0 --- I get 9 errors.
Which do I trust? If they don't show up in the DW validator, can I simply ignore them? Or do I use both? (the link above shows the errors found by the online validator, most of which I already fixed)..
Use the W3 validator online. It is much more thorough than DW's built-in validator. There are some errors from the W3 validator you can ignore, such as some that are generated from the Spry functionality.
