Community colleges are for learning skills. “Learn HTML” is appropriate as a community college course. Universities are more… well, universal in their approach to education.
We have "community colleges" here but they're a little more holistic than that, so I'd always been assuming the US ones were more like ours.
But it sounds more like a US community college is more like what's usually branded and adult education centre here if "learn HTML" is the kind of agenda.
"Community college" in the US can offer everything from remedial high school for adults, via technical certification and job skills training to 'real' university level education and university associate degrees.
It really just depends. I went to a community college and took maths through calculus 3, a discrete math course, some gen eds like history, english composition, etc. But there are also those kind of remedial adult education and specialized "how to" courses as well.
