Just finished a html lesson about entities

I just did another lesson on w3. It was about "entities" in html. It was a pretty quick lesson that mostly just gave a bunch of examples of entities, which are things that you need to type in a shortcut or code to display in html (ie. something like a cent symbol, which isn't on a keyboard.

You write an entity by typing in either: &space or &#40 (& followed by a space or & followed by the number symbol (#) and a number).

That's it! Pretty straight forward.
