Let me be clear, I am a dog, I have paws and no thumbs, accessibility is super important to me!
jokes aside
click your profile name in the top right corner
click settings
scroll down to the themes option
You will find that you can change the theme startrek.website appears to you in. By default lemmy already has a couple loaded. We could easily add a special theme to this website that was fun and star trek themed that was opt-in for users, or at least easily opt-outable by going into the settings and changing the theme.
We have a fantastic freedom here to indulge in a very treky themed startrek.website while still making sure to value accessibility and flexibility for those that need it. Lemmy gives control to the user over which theme to choose to display startrek.website in (from the list of installed themes on the startrek.website server). That is one of the fun, but underappreciated aspects of fediverse software. You get to choose how everything looks!
On the note of making a lemmy theme focused on accessibility, I think the lemmy community would be more than thrilled if people created accessibility focused themes for startrek.website , other lemmy instances would surely benefit from that work too!
Again, this is just a fun idea that could only add to the community here, there is no danger in making it unaccessible.
