PostCSS: born from vendor prefix pain, now quietly shaping the CSS universe, alongside Google and Tailwind. What 12 years of building for devs taught us—mistakes, speed, burnout, alchemy, told by our very own @sitnikcode:

This means a lot to me. Sponsorship really makes a big difference for all open source projects.

I’m so into security because I really don’t want half the internet to be hacked by PostCSS, or any of my other projects (plus I’m making a privacy-first RSS reader right now)
And you can always donate to me for my efforts to protect the internet.

Autoprefixer 10.4.19 was released.
We finally removed `end value has mixed support, consider using flex-end` warning since now `end`/`start` now have good support.

We updated Firefox ESR versions. Please update browserslist in your dependencies to remove polyfills for old Firefox 102 ESR from your JS/CSS bundle.

Browserslist website now has “Hide docs” button.
This mode can be useful to show target browsers to your client/CEO without loosing focus on Browserslist docs.

Very clever ideas of using Browserslist website.
They are showing that you can use it to look into browsers market and as advanced version of Can I Use, not only to test your own Browserslist config.

As a frontender, I often face issues
1. When to use new JS/CSS feature?
2. When to remove polyfills/fallbacks?
3. Can I use 2 features at the same time?
In this thread I'll try to answer using browsersl.ist website. Its queries are more visual than @caniuse website!

Diving deep into PostCSS, an unacknowledged hero in the realm of web development. Embracing plugins rather than an entirely new tools, unleash unlimited potential for your CSS. Don’t fear, go create!

Browserslist is not only a config for Autoprefixer/Babel. The idea is to have a single place of project’s target browsers.
@Browserslist is for both tools and developers.
New developer will know where to look to know what browsers they need to support.

With evergreen browsers do we even need a @Browserslist?
Join us tomorrow with it's creator @sitnikcode as we talk about all the cool things he works on.

When I just created Autoprefixer, Chrome announced that they will not add any CSS vendor prefixes to Blink engine.

Will we perpetually need tools like autoprefixer?
@sitnikcode certainly hopes not!
Catch the full ep this Friday!
