Some very interesting results from testing background image downloads contained within media queries or overridden with media queries: it turns out that, in iOS at least, the browser is getting smarter and smarter.
Container queries can’t be used in the sizes attribute for responsive images. Here, Jason breaks down why that is (spoiler: it’s the lookahead pre-parser) and segues into a truly long term solution: a “magical” image format.
If you’ve ever thought it felt weird to put media conditions inside the HTML for responsive images, this will resonate.
A really great case study of a code refactor by Mina, with particular emphasis on the benefits of CSS Grid, fluid typography, and accessibility.
This solution to the mobile tap delay by the WebKit team sounds like what I was hoping for:
Putting
touch-action: manipulation;on a clickable element makes WebKit consider touches that begin on the element only for the purposes of panning and pinching to zoom. This means WebKit does not consider double-tap gestures on the element, so single taps are dispatched immediately.
It would be nice to know whether this has been discussed with other browser makers or if it’s another proprietary addition.
The transcript of a great talk by Wilto, focusing on responsive images, inlining critical CSS, and webfont loading.
When we present users with a slow website, a loading spinner, laggy webfonts—or tell them outright that they‘re not using a website the right way—we’re breaking the fourth wall. We’ve gone so far as to invent an arbitary line between “webapp” and “website” so we could justify these decisions to ourselves: “well, but, this is a web app. It… it has… JSON. The people that can’t use the thing I built? They don’t get a say.”
We, as an industry, have nearly decided that we’re doing a great job as long as we don’t count the cases where we’re doing a terrible job.
Tim has published the results of a whole bunch of testing he did on how different browsers deal with hidden or replaced images.
I’m wrong again …fortunately.
A CSS fix for sluggish tap responses on mobile.
