I'm looking for a way to align CSS Grid cells into two columns with some of the cells aligned left and some right but without any vertical gaps.
I have mocked the issue in codepen. I am trying to get the right column only to have no vertical spacing, is this possible?
.grid {
  width: 768px;
  display: grid;
  grid-template-columns: repeat(12, 1fr);
  .cell {
    background: tomato;
    margin-bottom: 8px;
    &.a {
      grid-column: 1/6;
    }
    &.b {
      grid-column: 7/13;
    }
  }
}
img {
  width: auto;
  max-width: 100%;
}
This is the space i'm trying to remove so the content sits directly underneath:
