There is some compatibility issues associated with anything other than hand coding for HTML (and for that matter, even with hand coding.)
The best choice for compatibility is Dreamweaver but you cannot use layers. Layers must be converted to tables to be used.
The worst choice is FrontPage. FrontPage is loaded with problems because it uses Microsoft and therefore internet explored specific code.
Items that will not work in other browsers include: Marquees –
Virginia website design can use a JavaScript scroller to create a similar effect that will work in the most common browsers. Bgsound tag - this is IE specific. Page Transitions - this is IE specific. Front Page generated Style sheets - this is IE specific and can have unexpected results or crash other browsers. Front Page generated DHTML - it is better to use JavaScript to create the effects you want since it is more likely to be cross browser compatible. Hover Buttons - this is IE specific and has been know to crash browsers including older versions of IE. You can use JavaScript, flash or CSS to get similar effects.
Other HTML Editors - the rest of the HTML editors will fall somewhere between Dreamweaver and FrontPage in cross browser compatibility. You just have to test the code your HTML editor generates
