I've just implemented the SwaggerDark.css file into my project and it works great.

However, one suggestion that will improve it even more. Some people prefer light mode and some prefer dark mode.
So rather than force dark mode on everyone, wrap the entire css file with the following so that it becomes reactive to the users dark theme OS settings!

@media only screen and (prefers-color-scheme: dark) {
...Rest of content goes here.
}

For people using browsers that support light/dark mode, this will now switch depending on their preferences.
