31.7.2019
The point of the <portal> element (behind a flag in Chrome Canary) is that you can preload another whole page (like <iframe>), but then have APIs to animate it to the current page. So "Single Page App"-like functionality (SPA), but natively. I think that's pretty cool. I'm a fan...

Grid, content re-ordering and accessibility
13.6.2019
Take this:
<ol>
<li>Get hungry</li>
<li>Order pizza</li>

There are a few differences between keyboards and screen readers and Léonie Watson highlights of them:

Color contrast accessibility tools
29.5.2019
Accessibility is all the rage these days, specifically when it comes to color contrast. I’ve stumbled upon a couple of tools this week that I think are pretty nifty for helping make sure that all of the text on our websites is legible regardless of what background color they might have.

“There isn't some way to know when—…?”
There is always a pause here. The client knows what they're asking, and I know what they're asking, but putting it into words—saying it out loud—turns unexpectedly difficult.
