Learning CSS Grid - 2????

CSS Property grid-template-rows and grid-template-columns

Below, I use the aliases grid-template-rows and grid-template-columns for grid-template:

<style>
  .grid {
    display: grid;
    grid-template-rows: 2rem 50px;
    grid-template-columns: 1fr 100px 1fr;
  }
</style>

They render exactly the same.
