Another terrific interactive tutorial from Ahmad, this time on container queries.
Everyone wants it, but it sure seems like no one is actively working on it.
Zach traces the earliest inklings of container queries to an old blog post of Andy’s—back when he was at Clearleft—called Responsive Containers:
For fun, here’s some made-up syntax (which Jeremy has dubbed ‘selector queries’)…
Trys describes exactly the situation where you really do need to use the Shadow DOM in a web component—as opposed to just sticking to HTML web components—, and that’s when the component is going to be distributed and you have no idea where:
This component needed to be incredibly portable, looking great on any third-party website, in any position, at any viewport, with any amount of content. It had to be a “hyper-responsive” component.
This is a very handy piece of work by Rich:
The idea is to set sensible typographic defaults for use on prose (a column of text), making particular use of the font features provided by OpenType. The main principle is that it can be used as starting point for all projects, so doesn’t include design-specific aspects such as font choice, type scale or layout (including how you might like to set the line-length).
Progressive enhancement is a design and development principle where we build in layers which automatically turn themselves on based on the browser’s capabilities.
The idea of progressive enhancement is that everyone gets the perfect experience for them, rather than a pre-determined “perfect” experience from a design and development team.
Hallelujah! We’re finally getting our two wishes for CSS animations and transitions:
- Animating to and from
display: none;for the sake of enter/exit animations.- Animating to and from the intrinsic size of an element (such as
height: auto;).
Going back to school in Amsterdam.
Improving performance with containment.
I have some very talented friends.
CSS logical properties here, they just aren’t evenly distributed yet.
An exception to my general rule that ARIA attributes should be added with JavaScript.
