This update now makes it possible for universal app customisers to have support for custom CSS.

You can now edit the CSS of your customiser while you are previewing it in our admin application.

Previously, CSS could only be applied by editing the shopify theme itself, which made it impossible for universal app customisers to applly custom css.

This feature makes it even easier to have your customiser match your brand and style.
