Custom CSS Styling

For advanced customization, add CSS to the Custom Styles field. This CSS applies only to your Back in Stock form and won't conflict with your theme.

Common CSS Examples:

Square button corners:

.btn { border-radius: 0; }

Hide variant dropdown (all products):

select#variants { display: none; }

Hide variant dropdown (single-variant products only):

select.single_variant_product { display: none; }

Changes appear in the preview panel as you edit
CSS only affects the Back in Stock popup form
Preview shows success and error message styling
