I know that macOS / Safari displayed the alt text for broken images through Safari 17.0 (visually clipping as necessary).

Testing in macOS 14.4.1 / Safari 17.4.1, however, shows me that alt text is no longer displayed.

Has anyone else noticed this regression?

@aardrian I tested this last year and determined that desktop Safari only renders alt text if it fits within the image’s dimensions:

@simevidas Ah, good lead. Thanks! That is something I can test.

I did notice this behavior change for even single-word alt though.

@aardrian @simevidas That's definitely it, and it's been like this forever. I gave an entire talk about alternative text rendering in 2017. https://speakerdeck.com/hteumeuleu/the-great-mess-of-alternative-text?slide=87

@HTeuMeuLeu
Yay.

I discovered something novel while testing. Turning on VO while in macOS/Safari makes images with images/alt text CSS generated content resize. I’ll make a video later (after meetings), but ref page:
