    - `grid-template-columns: repeat(2, 1fr);` cria duas colunas de tamanho igual (1fr = 1 fração do espaço disponível).

    - `grid-column: 1 / 3;` faz com que o item `.large` comece na linha da coluna 1 e termine ANTES da linha da coluna 3, ocupando duas colunas.
    - `grid-row: 1 / 3;` faz o mesmo para as linhas, fazendo-o ocupar duas linhas de altura.
