SupportAlthough there is no registration fee, it would be SUPER nice if you’d drop a few $/€ to support Timothée with the instance hosting costs. This instance is hosted in France on OVH servers via 
Masto.host (Galaxy Plan + ElasticSearch add-on + 1 Extra Resources add-on) for $130.80/month (many thanks 
@Hugo for all the good work!) and has a custom domain for €44.45/year at Infomaniak.com for a total bill of ~$1632/year (~$136/month).

this official page or explore the curated selection below.
WebmacOS / iOSAndroidAppearanceMastodon.design uses a 
custom theme with the following features:
 - Warm light theme (inspired by Obsidian one)
- Responsive 4 columns layout for advanced web interface on desktop
Custom CSS works at the instance level, so if you want to use you own custom CSS, you need to use add-ons like 
Stylus or 
Live CSS Editor. For example, you can add .layout-single-column .colums-area__panels { flex-direction: row-reverse } if you prefer to use the single-column layout with the logo and navigation menu on the left, and the search bar and compose form on the right.
If you miss the Twitter X’s user interface, you can use the advanced custom theme 
Mastodon Bird UI designed by  
Roni Laukkarinen.
Code of ConductIf you would like to join Mastodon.design or already have, you agree to behave according to our Code of Conduct below:AccessibilityPlease make sure you caption the images you upload. Image descriptions, also called alternative text or alt text, are text descriptions of an image. These descriptions support people who are blind, have low vision, use assistive technology, live in low-bandwidth areas, or want more context. The goal of writing image descriptions is to be clear and concise, while giving more context to your post. Here’s a list of recommendations for writing great image descriptions:
 - Capture what's important
- Be succinct, clear, and detailed
- Be objective
- Write out or summarize text in images
- Watch out for acronyms and abbreviations
- Include the image type details
- Use regular sentence structure and letter casing
- Avoid redundant information
- Take care with complex visuals
For those who want to improve their knowledge, here are two comprehensive guides on the subject: 
Media size & qualityPlease reduce your images’ size and compress them before uploading. Mastodon automatically downscales images to 1.6 megapixels (enough for a 1280×1280 image) 8.3 megapixels (enough for a 3840×2160 image)
* and compresses JPEG and PNG with a quality of 90
**, but you can often get much better compression by using free tools like 
Squoosh (web app), 
TinyJPG (up to 20 images, works for PNG),
