I have worked in a number of systems that let you write HTML code, but the editors were not terribly great at it. Historically, Visual Studio’s HTML editing capability has not been good, though those tools have improved over time. I know some developers who will put up with it for the sake of dealing with fewer tools, while others will gladly work in a different tool specialized for HTML and make them all cooperate. I have been leaning more and more toward using a separate tool, as my patience with poor tools wears thinner. What about you?
