Delete "publish with ghost"

Hey, I would like to remove the Publish with ghost button in the portal using Css, it’s possible?

Thanks a lot.

I think it’s not possible to remove it without changing the Core of Ghost. I’ve looked into themes on how to change it without success.

You can’t change portal text from your theme file. It comes from Ghost core installed file.
This is the file location. /var/www/ghost/versions/{version}/core/shared/config/defaults.json

If you use a self hosted ghost, you can follow this instruction. Remove "Publish with Ghost" button on portal - #8 by JavowiecPL
