CSS グリッド レイアウトを使用して、各要素の幅が同じで、下部の要素が常に上部の要素より 50 ピクセル下にある石積みグリッドを作成するにはどうすればよいですか?

grid-container {
  display: grid;             /* Enables the grid layout */
  grid-auto-rows: 50px;      /* Defines the height of each row to 50px */
  grid-gap: 10px;            /* Sets the gap between the grid items */
  grid-template-columns: repeat(auto-fill, minmax(30%, 1fr)); /* Defines the columns to have a minimum width of 30% */
}

[short] {
  grid-row: span 1;         /* Makes the element span only one row */
  background-color: green;
}

[tall] {
  grid-row: span 2;         /* Makes the element span two rows */
  background-color: crimson;
}

[taller] {
  grid-row: span 3;         /* Makes the element span three rows */
  background-color: blue;
}

[tallest] {
  grid-row: span 4;         /* Makes the element span four rows */
  background-color: gray;
}
