Using CSS GRID for creating layouts with customized grid-template-areas that include empty cells and automatic placement

Struggling with implementing the css grid layout module to showcase a 12-column, 3-row grid.

The initial row should only contain two elements, positioned on each side of the grid with empty cells in between using ten periods.

Subsequent rows should automatically display the remaining elements.

Considering the use of grid-template-areas for better control over placement but facing issues as it requires specifying individual grid-area names for all elements.

Encountering complications while attempting to set the grid-area property to 'auto' for the remaining cells to fill the third row, observing that they occupy the empty cells from the first row instead.

Would appreciate advice on the most efficient solution to resolve this problem.

Provided below is the code snippet:

.grid {
  display: grid;
  grid-template-areas: 
  "elem1 . . . . . . . . . . elem2" 
  "elem3 elem4 elem5 elem6 elem7 elem8 elem9 elem10 elem11 elem12 elem13 elem14";
}
.elem{
text-align: center;
color: white;
}
...

<div class="grid">
  <div class="elem elem1">
    elem1
  </div>
  ...
</div>

Your help is greatly appreciated.

Answer №1

When utilizing the grid-template-areas property within an implicit grid, the grid auto placement algorithm seeks out unoccupied cells to fill before creating a new row (refer to bottom for further details).

Simply specify your desired layout:

.elem:nth-last-child(-n + 6) {
  grid-row-start: 3;
}

This directive alters the default auto-placement process by positioning the last six items on row three.

.grid {
  display: grid;
  grid-template-areas: 
    "elem1 . . . . . . . . . . elem2" 
    "elem3 elem4 elem5 elem6 elem7 elem8 elem9 elem10 elem11 elem12 elem13 elem14";
}

/* NEW */
.elem:nth-last-child(-n + 6) {
  grid-row-start: 3;
}

.elem{
  text-align: center;
  color: white;
}
.elem1 {
  background-color: blue;
  grid-area: elem1;
}
.elem2 {
  background-color: red;
  grid-area: elem2;
}
(elem3-elem20 styling continues...)

<div class="grid">
  <!-- Grid item elements -->
</div>

The Grid Item Placement Algorithm consists of five main steps (0-4).

One key initial step involves positioning grid items that are not automatically placed, giving priority to items with specified positions.

Finally, in the process comes Position the remaining grid items, which states the following:

The auto-placement cursor determines the current "insertion point" in the grid, which is defined as a pair of row and column grid lines. Initially, the auto-placement cursor is set at the beginning row and column lines in the implicit grid.

This section also clarifies why auto-placed items begin on row 1, column 2:

If the item has automatic grid positioning in both axes:

Increase the column position of the auto-placement cursor until either this item’s grid area does not overlap any occupied grid cells, or the cursor’s column position, along with the item’s column span, exceeds the number of columns in the implicit grid, identified earlier in this algorithm.

Answer №2

To simplify the layout, utilize the default grid-auto-flow:row property and specify the start/end points for the "1st row - right" div using the grid-column attribute.

This eliminates the need for grid-areas altogether.

Check out the result below:

.grid {
  display: grid;
  grid-template-columns: repeat(12, 1fr);
  grid-auto-flow: row; /*typo corrected*/
}

.elem {
  text-align: center;
  color: white;
}

.elem1 {
  background-color: blue;
}

.elem2 {
  background-color: red;
  grid-column: 12/13;
}
...

Answer №3

To create a grid layout, you can insert an empty div in the HTML and use grid-template-columns to structure it accordingly. Here is an example:

.grid {
  display: grid;
  grid-template-columns: repeat(12, 1fr);
}

.spacer {
  grid-column: 2 / span 10;
}

.elem {
  text-align: center;
  color: white;
}
... (CSS classes continue)

<div class="grid">
  <div class="elem elem1">
    elem1
  </div>
  <div class="spacer"></div>
  <div class="elem elem2">
    elem2
  </div>
