Using CSS Grid to Stack Elements

Published by on

To stack elements using CSS, we previously had to turn to absolute positioning and z-index tricks. Yet with CSS Grid, there's a new way to do this. To show what I mean, we're going to build this example component:

What A Badge

First, we need a few HTML elements:

<div class="grid">
  <div class="back" />
  <div class="front">What A Badge</div>

The .back element could be an image or something more interesting. The following style declarations show how to stack the .back and .front elements on top of each other:

.grid {
  display: grid;
  grid-template-rows: auto min-content 16px;

.back {
  grid-area: 1 / 1 / 4 / 2;

.front {
  grid-area: 2 / 1 / 3 / 2;
  margin: 0 -20px;

The trick is to use overlapping grid-area values for the elements you want to stack. Use grid-template-rows (or grid-template-columns) to lay out the elements. Additionally, you can use (negative) margin to position the stacked element relative to the grid for even more flexibility.

The stacking order follows the order in the DOM: the last element will be on top of the previous element(s).

The min-content value for the second row of the grid ensures the row takes the height of the stacked .front element, while the auto value for the first row makes it occupy the rest of the available space.

This idea is certainly not new. For instance, it was presented in How to Stack Elements in CSS. This scrap presents the same idea in a more focused way, and with a different example use case.

Support for CSS Grid is currently great across browsers, so you can go ahead and use all of this today!
