Complete the code to place the grid item in the first column.
.item {
grid-column: [1];
}The grid-column property with value 1 places the item in the first column.
Complete the code to make the grid item span across two columns.
.item {
grid-column: [1];
}The value span 2 tells the grid item to cover two columns starting from its current position.
Fix the error in the code to correctly place the grid item starting at column 2 and ending at column 4.
.item {
grid-column: [1];
}The correct syntax is start / end, so 2 / 4 places the item from column 2 to 4.
Fill both blanks to place the grid item starting at row 1 and spanning 3 rows.
.item {
grid-row-start: [1];
grid-row-end: [2];
}Start at row 1 and span 3 rows using span 3 for the end.
Fill all three blanks to create a grid area named 'header' that starts at row 1, column 1, and spans 2 rows and 3 columns.
.item {
grid-area: [1] / [2] / [3] / 4;
}The grid-area shorthand uses row-start / column-start / row-end / column-end. Here, start at row 1, column 1, span 2 rows, and end at column 4 (which is 1 + 3 columns).
