I installed Materialize CSS by inserting a single CDN link into the <head> of my HTML file so I don't have to download anything into my computer.
From the Materialize library I included cards, headings, and containers.
I wrote the HTML structure, applied built-in classes such as container and card,
and Materialize automatically styled them.
At first, the styles did not appear because I had pasted the wrong CDN link. I fixed this by copying
the correct link from the Materialize website. Another issue was that the card width was too wide; I
fixed this by placing everything inside a container class, which centers the content.
And finally, the biggest problem of all I STILL DON'T KNOW HOW TO CENTER A DIV.
(just kidding, sorta)
