3 CSS Grid Techniques to Make You a Grid Convert

This is the fifteenth post in a series examining modern CSS solutions to problems I've been solving over the last 13+ years of being a frontend developer.

CSS grid layout can feel daunting. In fact, I avoided it for several years and was a diehard flexbox fan.

Then I found the following 3 powerful properties/techniques in grid that completely changed my tune.

Spoiler, here's a tweet with all of them. Keep reading to learn a bit more!

1: Switch the Grid Flow Axis#

I first desired this behavior when I wanted X-axis alignment of variable width items, and also desired to leverage grid-gap.

The Code#

grid-auto-flow: column;

What it does#

Default grid flow is oriented to "row" layout, which is complementary to block layout, where items flow down the page along the Y-axis.

This switches that default behavior to "column" which means items default to flowing along the X-axis.

Things to note#

Note: once flexbox gap is fully supported, it will likely be the better method for this outcome due to also having wrapping behavior

When to use#

For short content where variable widths are desirable, such as a navbar or list of icons, and when wrapping either isn't a concern or a media query can be used to flip this property.

2. XY Center Anything#

Literally the thing everyone makes fun of when CSS comes up as a topic:

"How do you center a div?"

Grid has the easiest answer!

Psst - interested in lots of solutions to centering? Check out the "The Complete Guide to Centering in CSS"

The code#

place-content: center;

What it does#

Centers any child content both vertically (Y) and horizontally (X) 🙌

Things to note#

When to use#

Anytime you want to center something vertically and horizontally.

3. Intrinsically Responsive Grid Columns#

The code#

:root {
--grid-col-breakpoint: 15rem;
}

.grid-columns {
grid-template-columns: repeat(auto-fit, minmax(var(--grid-col-breakpoint), 1fr));
}

What it does#

The unique-to-grid functions of repeat() and minmax() along with the auto-fit keyword work together to create an outcome where immediate children become equal-width, responsive columns.

As the grid container resizes, upon hitting the supplied value for --grid-col-breakpoint, the columns begin to drop to a new virtual row.

Use of the --grid-col-breakpoint CSS variables allows altering this "breakpoint" via inline style to accommodate various content within a layout or across components with only a single class.

Things to note#

Check out a more comprehensive explanation of what's happening in "Solutions to Replace the 12-Column Grid"

When to use#

If you're in need of an intrinsically responsive grid with equal-width columns.

This behavior is also one of two viable "container query" methods that we currently have available since it responds to container width instead of being controlled by media queries.
