This is the best App for custom CSS in my opinion. - Easy to use - Support responds quick - It is free!!

— Gewerbefabrik

Worked perfectly - only suggestion is a "dark mode" toggle. The selectors appear only slightly lighter than the background, which I think is difficult to see.

Perfekt! Einfach Theme auswählen und Custom CSS hinterlegen. Perfekt für kleinere Änderungen ohne den Template-Code zu bearbeiten.

I hate this app, which sometime can not apply mobile code, sometime can not open app , sometime .. But I still have to use , because shopify is really limted in coding,.,,

It is easy as the name is. I followed their instructions in uninstalling but it still left files/css on my website. I sent a message to support about this and there's been no response 1 month down the road.

Uhhhhh ... all of my CSS erased? I didn't erase anything. Opened the app and everything was gone. Now I'm adding new CSS and nothing's changing. Has the app stopped working? It was working fine before.
