Same Custom CSS for all posts?

Hello,

Is there any way to share the custom CSS for all posts at once, instead of copy pasting it ? (With no theme edit?)

Try to use Code Injection and then Site header.
Header and Footer are injected on every post.

To be clear, this is referring to the global Code Injection settings in the main settings area, not the per-post Code Injection settings found in the editor.
