Locked CSS file

Hello I am using the online version of Pinegrow I am also using one of your templates what I’m trying to modify the CSS that comes with the template it says that it’s locked is there a way to unlock CSS file?

Indeed, the tailwind.css stylesheet is associated with the design panel and should not be used to add “standard” classes to your creation (hence its locked).
Tailwind styles are applied through the Element properties tab (see screenshot below).
