After a wysiwyg css editor that makes w3 valid html

[aceatuumiszincepj]

So basically trying to move away from frontpageran my page code through w3's html tidy and corrected the incompatible bits. so after the html tidy im wanting a css/html wysiwyg editor that should run my pages code in wysiwyg mode and not have any issues with compatibility. anyone see any issues as im going from fp to this?
