As I walked around the classroom last Tuesday, I saw a few students consulting the website named W3schools. I do NOT recommend that site. It is not the best one for accurate, up-to-date information about how to use HTML and CSS today.
In the sidebar of this course website, you’ll see a list of resources that I DO recommend. For looking up the right way to use HTML tags — and CSS selectors and properties — your first choice should also be MDN. You can get what you need in a Google search by adding mdn to your search terms. (I always search this way.) For example:
headings html mdn
If you find MDN not to your personal taste, my second recommendation is HTML Dog. It is reliable and accurate.
Note that W3schools is NOT associated with the official World Wide Web Consortium (W3C). Their name is misleading.
