@ -56,6 +57,20 @@ I have two responses:
|
|||
1. If an image isn't essential, you shouldn't include it inline.
|
||||
2. Yes, users could disable images. That's *their* choice. If your page uses lazy loading, you've effectively (and probably unintentionally) made that choice for a large number of users.

## About custom colors
|
||||
|
||||
Some users' browsers set default page colors that aren't white-on-black. For instance, Linux users who enable GTK style overrides might default to having white text on a dark background. Websites that explicitly set foreground colors but leave the default background color (or vice-versa) end up being difficult to read. Here's what this page would look like if it messed with the colors carelessly:
|
||||
|
||||
=> gemini://seirdy.one/misc/website_colors.png Screenshot of this page with some unreadable text
|
||||
|
||||
It's got a grey background, a header with unreadable black/grey text, and unreadable white-on-white code snippets
|
||||
|
||||
If you do explicitly set colors, please also include a dark theme using a media query:
|
||||
|
||||
```
|
||||
@media (prefers-color-scheme: dark).
|
||||
```
