Jonathan shares his notes on that great flexbox container queries article from Heydon that I linked to.
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!
I think Cathy might’ve buried the lede:
The knock on effect of this was removing media queries. As I moved towards some of the more modern features of CSS the need to target specific screen sizes with unique code was removed.
But on the topic of Sass, layout is now taken care of with CSS grid, variables are taken care of with CSS custom properties, and mixins for typography are taken care of with
Personally, I’ve always found the most useful feature of Sass to simply be that you can have lots of separate Sass files that get combined into one CSS file—very handy for component libraries.
‘Sfunny, this exact use-case (styling a profile component) came up on a project recently and I figured that CSS grid would be the right tool for the job.
The slides and notes from a great presentation by Eric Bailey that takes a really thoughtful deep dive into media types, media queries, and inclusive design.
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).
Here’s a really smart approach to creating container queries today—it uses
ResizeObserver to ensure that listening for size changes is nice and performant.
There’s a demo site you can play around with to see it in action.
While the strategy I outline in this post is production-ready, I see us as being still very much in the early stages of this space. As the web development community starts shifting its component design from viewport or device-oriented to container-oriented, I’m excited to see what possibilities and best practices emerge.
This homepage is media-querytastic. It’s so refreshing to see this kind of fun experimentation on a personal site—have fun resizing your browser window!
24 Ways is back! Yay! This year’s edition kicks off with a great article by Hui Jing on using
Chances are, the latest features will not ship across all browsers at the same time. But you know what? That’s perfectly fine. If we accept this as a feature of the web, instead of a bug, we’ve just opened up a lot more web design possibilities.
Chris rounds up the discussion that’s been happening around container queries, for and against.
Personally, I’d like to see about 100 different use cases fleshed out. If it turns out some of them can be done sans container queries, awesome, but it still seems highly likely to me that having container queries available to us would be mighty handy.
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.
Unsurprisingly, I completely and utterly agree with Ethan’s assessment here:
I’ve written some code that’s saying, “Once the screen is this size and the element appears in a different, smaller container, use a narrower layout on this element.”
But, well, that’s weird. Why can’t we apply styles based on the space available to the module we’re designing, rather than looking at the shape of the viewport?
I also share his frustration with the “math is hard; let’s go shopping” response from browser vendors:
There’s an incredible clamor for container queries, with folks from every corner of the responsive community asking for something that solves this problem. So personally, I’d love to see at least one browser vendor partner with the RICG, and get properly fired up about this.
We had to drag browser makers kicking and screaming to responsive images (to this day, Hixie maintains it’s not a problem that needs solving) and I suspect even more activism is going to be needed to get them to tackle container queries.
This is so great! Charlotte takes two previous ideas she’s been writing about (quantity queries and flexbox) and puts them together in a new way.
It took me a while to get around what the nth-child selectors are doing here, but Charlotte does such great job of explaining the CSS that even I could understand it.
Charlotte is a big fan of feature queries.

The Search For The Holy Grail: How I Ended Up With Element Queries, And How You Can Use Them Today – Smashing Magazine
Just recently on a Clearleft project, some of us were discussing whether there was a reason not to use
rems instead of
ems for media queries. Apart from one older browser implementation difference, we couldn’t come up with much.
Some in-depth research here supports the use of
em values for media queries. Very good to know.
