Understanding Layout Algorithms
Josh is great at explaining tricky concepts and here he’s really set himself a challenge: explaining layout modes in CSS.
How Flexbox Works
A really deep dive into flexbox. This is a great example of what I categorise as “thinking like a browser” (a skill I recommend for any front-end developer).
Modern CSS in a Nutshell - Cloud Four
I like this high-level view of the state of CSS today. There are two main takeaways:
- Custom properties, flexbox, and grid are game-changers.
- Pre- and post-processers are becoming less and less necessary.
This is exactly the direction we should be going in! More and more power from the native web technologies (while still remaining learnable), with less and less reliance on tooling. For CSS, the tools have been like polyfills that we can now start to remove.
Alas, while the same should be true of JavaScript (there’s so much you can do in native JavaScript now), people seem to have tied their entire identities to the tooling they use.
They could learn a thing or two from the trajectory of CSS: treat your frameworks as cattle, not pets.

This is such a great way to explain a technology! Chris talks through his thought process when using flexbox for layout.
Understanding the Albatross - Snook.ca
Jonathan shares his notes on that great flexbox container queries article from Heydon that I linked to.
The Flexbox Holy Albatross | HeydonWorks
Er …I think Heydon might’ve cracked it. And by “it”, I mean container queries.
This is some seriously clever thinking involving CSS custom properties, calc, and flexbox. The end result is a component that can respond to its container …and nary a media query in sight!
Your Brain on Front-End Development | CSS-Tricks
I find this soooo relatable:
I know when I look at a design (heck, even if I know I’m not going to be building it), my front-end brain starts triggering all sorts of things I know will be related to the task.
Difference is, Chris comes up with some very, very clever techniques.
Getting Started With CSS Layout — Smashing Magazine
Rachel gives a terrific explanation of CSS layout from first principles, starting with the default normal flow within writing systems, moving on to floats, then positioning—relative, absolute, fixed, and sticky—then flexbox, and finally grid (with a coda on alignment). This is a great primer to keep bookmarked; I think I’ll find myself returning to this more than once.
Grid to Flex
Una has put together this handy one-pager of flexbox fallbacks for some common grid layouts.
Best Practices With CSS Grid Layout — Smashing Magazine
A great set of answers from Rachel to frequently asked questions about CSS grid. She addresses the evergreen question of when to use flexbox and when to use grid:
I tend to use Flexbox for components where I want the natural size of items to strongly control their layout, essentially pushing the other items around.
A sign that perhaps Flexbox isn’t the layout method I should choose is when I start adding percentage widths to flex items and setting
flex-growto 0. The reason to add percentage widths to flex items is often because I’m trying to line them up in two dimensions (lining things up in two dimensions is exactly what Grid is for).

A really nice example of progressive enhancement: creating a layout with inline-block, then flexbox, then Grid.
Questioning Container Queries / Paul Robert Lloyd
Paul’s being contrary again.
Seriously though, this is a good well-reasoned post about why container queries might not be the the all-healing solution for our responsive design problems. Thing is, I don’t think container queries are trying to be an all-encompassing solution, but rather a very useful solution for one particular class of problem.
So I don’t really see container queries competing with, say, grid layout (any more than grid layout is competing with flexbox), but rather one more tool that would be really useful to have in our arsenal.
CSS Grid. One layout method not the only layout method
Grid is only a replacement for float-based layout, where float-based layout it being used to try and create a two-dimensional grid. If you want to wrap text around an image, I’d suggest floating it.
Grid is only a replacement for flexbox if you have been trying to make flexbox into a two-dimensional grid. If you want to take a bunch of items and space them out evenly in a single row, use flexbox.
