I think learning web design or development in a class room setting is a waste of time and money. Pick-up some books and start reading. The most up-to-date information is going to be in books not some fossil teaching web design or development when they were practicing it 5 or 10 years ago.
That said, HTML is not very difficult to learn. Like anything though it takes a significant amount of time learn well and truly master. This is especially true in regards of writing valid, semantic, minimal mark-up. For now though just pick-up a good book and go from there.
The other technology that plays a significant part in the design of websites is CSS. However, writing CSS well requires at least an intermediate understanding of HTML. So you should first learn HTML than begin picking up CSS.
