As per the title.

This depends on the chromium version QtWebEngine ships with. You can see a versions table in the Qt documentation, then you would need to check your current Qt5Core and QtWebEngine versions. The expected features are attached to the lower version between these two; if using QtWebEngine 5.15.8 but QtCore 5.15.2, then your current version is 5.15.2.

The most common version is the 5.15.2, so it means web-greeter uses Chromium v83. Therefore, you can expect the following features:

CSS in Chromium v83 it's more outdated than JavaScript, as features like Flexbox gaps are not available. Check caniuse for more information.

On a fully updated Arch Linux with Plasma I find the following. Assuming the directory names are correct, you are spot on with version 5.15.2. Thanks a lot. In the new year, I'm going to read into the docs linked from the versions table page that you linked. Thanks a lot for this information. And I wish you a Happy New Year. All the best.

So, according to the table, the chromium version you're using is v83, as expected~

Have a happy new year!
