Problem Description

On iOS, there is no solution for Safari that completely supports user styles.

Proposed Solution

Add native support for installing userstyles. There is support in https://github.com/quoid/userscripts, but it is very limited and does not support most standards: https://github.com/quoid/userscripts/issues/711

Alternatives Considered

Additional Information

@Swen90 for userscripts there is a separate request: https://github.com/AdguardTeam/AdguardForiOS/issues/1542

I am asking about userstyles only here.

Hello @rakleed

Ok, I just initially thought about similar functionality as on the Android version where userstyles and userscripts were simultaneously added

As for userstyles separately, at the moment this feature is technically achievable. I've added this task in our backlog. However, there is no exact date when this feature will be implemented yet.

Of the alternatives, I can recommend an application in which you can also use your userstyles https://apps.apple.com/ua/app/userscripts/id1463298887

I'll leave this request open, let's see how many people will be interested and upvote it 👍
