A nested grid is where a grid item becomes a grid itself. Here's a brief overview and demonstration.
Css Grid Table Layout
The CSS Grid Layout Module offers a grid-based layout system, with rows and columns, making it easier to design web pages without having to use floats and positioning. You should be able to do plenty of “good enough” CSS grid yoga by now. But here is one last piece to the basics of CSS grid – An alternate way to create a grid by defining a template and specifying areas. For example: Yep, that is essentially a 4 columns 3 rows grid But we have specified which cell is in which area.
Method of using a grid concept to lay out content, providing a mechanism for authors to divide available space for layout into columns and rows using a set of predictable sizing behaviors. Includes support for all grid-. properties and the fr unit. What I like the most about this css table is one of its border. One side of the table border for each cell has a css color according to the type of data it contains. This makes it easy to identify the category of data without having to do much however its not all there to offer. CSS Grid Layout allows you to build advanced grid layouts in CSS instead of HTML like the case for tables for example. Unlike CSS floats and HTML tables you can create a grid layout in a straightforward way. You simply need to use an HTML element with its display property set to grid or inline-grid. This way, any elements contained in the.
Grid items can become grids themselves with CSS grid layout. You can then place grid items inside the grid item, therefore creating a nested grid.
To create a nested grid, all you have to do is apply
display: grid (or
display: inline-grid) to the grid item and it becomes a grid. You can also apply
display: subgrid to create a subgrid. See below for more information on subgrids.
Here's an example:
That should look like this in the browser:
Most grid properties aren't inherited, which means that your nested grid won't inherit the values from its parent grid. This allows you to make changes to the parent grid without inadvertently affecting the nested grid.
For example, say you have
grid-auto-flow: column on the parent grid but you haven't set this property on the nested grid. In this case the nested grid will be set to
row because that's the initial value of that property.
Notice that on the parent grid, the numbers now flow vertically down the columns instead of horizontally across the rows, but the nested grid still flows horizontally across the rows.
However, many other CSS properties are inherited, so you won't necessarily have to reset all properties.
The CSS Grid Layout Module defines a
subgrid value for the
display property. However, at the time of writing, no browser supports this feature.
This should prove to be a useful feature once it's implemented.
A subgrid is a nested grid, but with
display: subgrid. This makes it a special type of grid container box that participates in sizing the grid of the parent grid container. In other words, the content of the subgrid affects the sizing of the parent grid, allowing content to align across both grids.
Html Table With Gridlines
Below is an example of where this could be useful (this is based on an example in the W3C specification).
Here's a list of form elements:
And here's some CSS that sets the list to a grid, and each list item to a subgrid.
This would result in the labels and inputs aligning, and a border placed around each list item. Setting each list item to a subgrid of the list means that there shouldn't be any alignment problems with the form controls not lining up, etc, because each list item will be contributing to the sizing of the parent grid.
