  • With the style applied
  • Yellow and Purple option
  • Blue and Orange option
Toot Button Animation


This is a flat Mastodon theme based on KindlyFire (’s personal one, available at
This style is quite short and simple so it shouldn’t be too hard to customise the colours if you want to.

Special thanks to for their help figuring out how to change some stuff!

Don’t forget to edit the target domains if the new theme doesn’t show up on your instance!

Now includes bottityttö’s Variable Width theme as an option

Feel free to use this theme by default on your instance, as is the case on!

More info
- hopefully fixed the toot background sometimes not being the right colour on the latest Mastodon version

- added a new wide option that I copypasted from bottityttö’s theme due to popular request. I hope it’s ok, it was CC-0 but idk

- changed the privacy dropdown to the appropriate colour
- added an optional animation to the toot button when hovered or clicked

- changed the colour of the buttons below the toot compose box

- added a new colour option: blue and orange, for a slightly more vanilla look

- fixed the headers not displaying (and added a pretty neat opacity gradient so it blends with the rest of the profile)

- added a new colour option: yellow and purple

- changed the magnifier icon to green so you can see it when hovering the search bar, and you can see the “erase all” button when typing

- reverted the reply and favourite buttons to the original colour

- made the reply indicator look less aggressive

- made the name autocompleter thingy look more like the rest of the theme
- fixed the user profile view looking like garbage

- added more instances to the default supported ones (you can still edit the css to add yours if it’s not in there)

- changed the “show more button” to look less aggressive

- release
