I use Visual Studio for teaching HTML. We use HTML 4.01 Transitional. Visual Studio defaults to XHTML 1.0, and I need to solve one problem with a typical difference among these two HTML standards: Whenever we enter
Tools -> Options -> Text Editor -> HTML -> Formatting -> Tag Specific Options
You may define behavior for each individual tag. Hit CTRL + K + D to reformat the document and you should see the change.
