 Start classes aim to replace our default grid's offset classes, but they're not entirely the same. CSS Grid creates a grid template through styles that tell browsers to "start at this column" and "end at this column." Those properties are `grid-column-start` and `grid-column-end`. Start classes are shorthand for the former. Pair them with the column classes to size and align your columns however you need. Start classes begin at `1` as `0` is an invalid value for these properties.
