It takes as much energy to wish as it does to plan. — Eleanor Roosevelt
Container Queries, as in, the ability to style elements based on values from a particular element, like its width and height. We have media queries, but those are based on the viewport not individual elements. There are plenty of use cases for them. It's been said before, but I'll say it again, if container queries existed, the vast majority of media queries in CSS would actually be container queries.
Discussion about how to pull it off technologically gets … Read article
Right now, we have the power to write CSS that only applies when the browser window itself is at certain widths or heights. Breakpoints, as it were. Super useful. What we don't have (natively) is the ability to write conditional CSS based on any particular elements (or "containers") properties. … Read article
I guess the plan is to stop with the "element queries" and start thinking and referring to them as "container queries". We've been following this saga for a while. Element queries have a serious pitfall: infinite loops.
.our-element:media(min-width: 500px) {
width: 499px;

This is a perfect example of making a case for new language features. Not just a vague "element queries! that would be awesome!" but laying out a real-world scenario, what we have to do to achieve it now, and why that's not ideal. Of course there are big challenges (see this and this) but those debates can be held elsewhere and not muddy the "why we need it" explanation.… Read article
Imagine something like these Transformer Tabs as a widget in a fluid column in a responsive design. Depending on the browser window width, perhaps this design is either 4, 2, or 1 column wide. When it breaks from 4 to 2, the column probably temporarily gets wider than it was, even though the screen is narrower. It would be preferable when writing the media query logic for those tabs to consider how much space the widget has available rather … Read article
Width based media queries are based on the entire browser window. If the browser window is narrower than 800px, do this. If the browser is window is wider than 400px, do this. But that's not always enough. Imagine a desktop 3-column layout at 1000px. Each column is 333px wide. Then you have a media query break at 800px which drops it to a 2-column layout, and with the third below. Even though the browser is now narrower, each column is … Read article
