We can achieve the same result as in example 2 using a shorthand syntax declaring the start and end values at once. Values are separated with a / and again it would be valid to omit the / and the end value as we are spanning only one track.

[fl_row] {
    display:grid;
    grid-gap: 10px;
    grid-template-columns: 1fr 1fr 1fr;
}
[fl_row] .a {
    grid-column: 2 / 3;
    grid-row: 1 / 2;
}
[fl_row] .b {
    grid-column: 2 / 3;
    grid-row: 2 / 3;
}
[fl_row] .c {
    grid-column: 3 / 4;
    grid-row: 2 / 3;
}
[fl_row] .d {
    grid-column: 1 / 2;
    grid-row: 1 / 2;
}
[fl_row] .e {
    grid-column: 1 / 2;
    grid-row: 2 / 3;
}
[fl_row] .f {
    grid-column: 3 / 4;
    grid-row: 1 / 2;
}
