How Can I Apply CSS Grid Properties to Deeply Nested Elements?

Grid Context and Nested Elements

In CSS Grid, grid properties are restricted to elements within a parent-child relationship. This limits the applicability of grid properties to elements that are directly children of a grid container.

Nested Grid Example

Consider a scenario where you attempt to position a deeply nested li element using grid properties applied to a top-level ul representing the grid container:

#orgChart ul.orgChartLevel1 {
  display: grid;
  grid-template-columns: 12px auto;
  grid-template-rows: 100px auto auto;
  grid-row-gap: 30px;
}

#orgChart li.orgChartLevel2b {
  grid-column-start: 2;
  grid-column-end: 3;
  grid-row-start: 2;
  grid-row-end: 3;
}

In this example, the li.orgChartLevel2b element is a descendant of ul.orgChartLevel1, but it is not a direct child. Therefore, the grid properties defined on ul.orgChartLevel1 do not apply to li.orgChartLevel2b.

Solution: Establish Parent-Child Relationship

To apply grid properties to deeply nested elements, you need to establish a parent-child relationship between the element you want to style and a grid container. This can be done by either:

• Applying display: grid or display: inline-grid to a parent element between the grid container and the desired element.
• Removing any intervening wrapper elements that block the parent-child relationship.

Note on Grid Containers Within Grid Items

It is important to note that grid items themselves can be grid containers. In such cases, the grid layout properties apply within the scope of the grid item that is defined as the grid container.
