Pretty nice. Congrats on finally posting your first blog 🫡.

Good article! It is also possible to center the div using CSS grid like so:

body {
  margin: 0;
  width: 100%;
  min-height: 100vh;
  display: grid;
  justify-content: center;
  align-items: center;
}

div {
  background: lightgreen;
  height: auto;
}
