I love to learn more and truly I had no clue you could add all the heading tags in one line. All the previous examples I saw online split them up.

I'm thinking to merge h4-h6 into one line since I rarely add anything extra besides centering those headers. It does save space and makes it easier to read the code.

I've been mostly teaching myself css and using the online tutorials but finding best practices and more efficient ways to accomplish the same thing is a bit harder to figure out.
