How to set global CSS?

[Alex_P]

For example, I want to add these 3 lines disabling the overlay after sign up Disable "Your first notification!" overlay on first login
What is the best way to do this for all themes?

Should I create a theme component? Or is there a simpler way to just add some CSS globally?

Creating a component and adding the component to all your themes is the best way.

If you’ve updated recently, we’ve added the ability to add a component to all themes in a single click from the theme component’s settings.
