centering items in css grid

Question

https://codepen.io/joseph-van-den-avont/pen/QWvraWR

I made this container using display:grid but I can't seem to figure out how to center the items in my grid horizontally. I've tried using justify-content:center but it won't work with how it's currently coded, and I am not experienced enough to know what to change myself to make it work. ‎‎‎‎‎‎‎‎‎‎I'm a beginner so any help would be greatly appreciated ;)

.grid {
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(200px, 1fr));
  grid-gap: calc(2em + 2vh) calc(1.5em + 1vmin);
  grid-auto-flow: row dense;
}

.card__image {
  display: block;
  max-width: 60%;
  margin: auto;
}

.card {
  display: inline-block;
}


/* ==== Styles Related to the callout ==== */

.grid .card:nth-child(14) {
  grid-column: -1;
  grid-row: span 2;
  align-self: center;
}

@media (min-width: 712px) {
  .grid .card:nth-child(14) {
    grid-column: -1;
  }
}

.grid .card:nth-child(14) .card__image {
  margin: 0 auto;
  object-fit: cover;
}

@media (min-width: 712px) {
  .grid .card:nth-child(14) .card__image {
    height: 100%;
  }
}

Answer 1

See here link

I used display flex, instead of grid.

.grid {
      display: flex;
      justify-content:center;
      align-items:center;
      grid-template-columns: repeat(auto-fill, minmax(200px, 1fr));
      grid-gap: calc(2em + 2vh) calc(1.5em + 1vmin);
      grid-auto-flow: row dense;
    }
