Save time with CSS grid area start/end shortcuts

Posted at — Jun 14, 2019

grid-column & grid-row both support a shorthand “slash” syntax where the first value represents the column or row start and the second value represents the column or row end. This is more concise than explicitly listing start and end positions, but not so terse as the four-way a/b/c/d syntax, which is harder to orient around.

.a {
  grid-column: 1 / 2;
  grid-row: 1 / 2;
