HTML uses a unique bracketed syntax. <!-- ... -->
CSS only uses the multi-line style,
/* ... */.
Most languages like JavaScript and the C-style backend languages use both // single comment and /* ... */ for multiple comments
Python and Ruby primarily use the pound sign (#) for single comments. Ruby is unique with its explicit =begin ... =end block for multi-line comments.
