CSS: styling Placeholders for broken Images without JavaScript

[poyribn]

According to DuckDuckGo Search Results,
the only 2 Ways to style Placeholders for broken Images with CSS are:

• Using JavaScript to tag broken Images with an Error CSS Class
• Or abusing the ::before and ::after pseudo-Elements
  because broken Image Placeholders display them and Images don’t

I would very much like Web Browsers to support an official, clean Solution for styling broken Image Placeholders —
so that i can easily make my Layouts legible if the Images dont load,
without having that Feature make my Website harder to maintain.

Links can be styled in all their different States:

• a
• a:visited
• a:active
• a:hover

I believe it is good for Images to have the same CSS Syntax for their different States:

• img
• img:broken or img:missing or img:invalid,
  whichever matches the official Name of broken Images
