Social media standard image accessibility tag with Alt instead of aria labels

[bit-pro-iew-eui]

Please use alt-attribute instead of aria-label to describe the social icon-image.

Label: Share to [social media name here]

Social sharing icons are applied as a CSS background of an a tag and not as an img tag.
alt attribute can only be applied to img tag and will be ignored on other tags.
The aria-label is thus a correct solution.
title attribute could also be used, but no all screen readers will read it.

Guideline ok.
Implementation in www.eak.admin.ch was done with img, the alt-tag is empty there.
