Now when I look at what articles I have for you this week, this seems very understandable. Soon we cannot use
.dev domains anymore, HTTPS CAA checks do not work with private network interfaces, and when I look at an admittedly great tutorial on how we can replace
scroll events with
IntersectionObserver, I see code that might have better performance but definitely is more complex than what we used to do with
EventListener. Our incredibly fast-changing environment expands very fast and we need to acknowledge that we as individual persons can’t know and understand everything. And that’s fine. Choose what you want to do, be sure on priorities, and then hire someone else for the remaining priorities you can’t do on your own.
- Mattias Geniar reminds us that Chrome, according to this commit in Chromium, will very soon preload
.devdomains as HTTPS via preloaded HSTS. The domain name has been bought by Google and they now want it to be exclusively accessible only via HTTPS. So if you use a
.devname in your projects—often on your local machine, registered manually via the
hostsfile, you should switch to the reserved
.testdomain name now or consider using
localhostinstead from now on. Once the patch lands in Chrome, you’ll not be able to access your projects anymore without a valid TLS certificate in place.
- HTTP Immutable Responses are now an official Internet standard. And it’s available in most browsers already.
- The videos from the Material Conference 2017 are all available now and have some interesting talks in it.
- Infusion is an inclusive, accessible documentation builder.
- The University of Cambridge shares why they’re unintentionally not able to issue TLS certificates anymore for their internal network domain
private.cam.ac.ukdue to the now required CAA check. In short: As the hostname cannot be checked by the certificate authority, they decline to issue a certificate now. The drawback of the otherwise quite useful mandatory CAA checks.
- Eric Bidelman shares how we can use an
IntersectionObserverto control or react upon
position: stickychanges. This replaces the need for
scrollevents, offering a much better performance.
- Lea Verou started a very useful discussion about specificity of the
:not()selector and why it would be useful to have a pseudo-class
:matcheswhich doesn’t carry any specificity.
- Manuel Matuzovic about how you should write CSS with accessibility in mind and which things to avoid.
