[] Move styling into localgov_base theme
[] confirm feature parity

Are we fully moving the templates and CSS out of alert banner into the theme?
We need templates in the alert banner module as its a custom entity.
I thought we also where planning on keeping basic CSS for the alert banner so it works out the box?

Hi @andybroomfield

I'm just moving things to the theme for now, so we can see how it works. We can then start backporting them to modules. The alert banner is a good example of where things should remain in the module.

Hi @andybroomfield

I don't see any changes needed in the Alert Banner for the new theme, except to change this class name (which won't affect anything) - localgovdrupal/localgov_alert_banner#157

I'll close this issue and leave that PR to you.
