Imagine, for a moment, that your browser stopped showing you images. You would still see them referenced in articles, you’d read conversations about them, people making jokes. What would this experience be like for you? You would certainly feel pretty left out.
I use the CSS :has() pseudo-class to provide an interactive alt text decision tree (from the W3C WAI Tutorial) that uses no script. It is progressively enhanced, so browsers without support for :has() still get all the content.
