Our friend @tfardet made a good suggestion to make #FediScience more accessible.
It is easy to forget putting a description on an image, gif or video. So we added some markup code (CSS) to our homepage/instance that puts a red border around images without description.
This border will only be visible to people on the FediScience homepage, not on apps and not on other instances.
Admins wanting to do the same can find example CSS code here: https://gist.github.com/FiXato/3de505b04efefd49a1e3568b70545234
