[Plugin development] Preferred way to add CSS with a plugin?

[DChiuch]

What is the preferred way to add CSS rules with a plugin?

I can insert inline CSS with a theme hook into the globalTemplate, but I think inline CSS is discouraged in IPS4. Any better way to do it?

Never mind, I just discovered the relevant part on https://www.invisionpower.com/support/guides/_/advanced-and-developers/4-0-developer-documentation/plugins-r283

Feel free to close this.

Actually... I've put a CSS file in my plugins\[plugin name]\dev\css directory, but it doesn't seem to be being included on my website. Do I have to do anything else?

Edit: Right, you have to download the plugin, uninstall it and reinstall it before any CSS files take effect. Sorry for this mess of a topic.

Hm, it should add the css files automatically if you have IN_DEV active

That would explain it, I have to turn IN_DEV off when I want to look at the front-end since it breaks my front-end at the moment.
