CSS to speech: alternative text for CSS-generated content

This technical article details the use of the CSS slash syntax (e.g., `content: url(...) / "alt text";`) to provide alternative text for content generated via CSS pseudo-elements like ::before and ::after. It covers why this is crucial for accessibility, how it integrates into the accessible name computation algorithm, and recent improvements in browser support for exposing this alt text to screen readers.
