I was finally able to set up the age-check verification, but I am having trouble uploading a background image. I do not know where to find theme assets to upload an image as well as the edit html/css page? Please help
Thank you!
Topic summary
A tutorial explains how to add age verification to Shopify stores selling age-restricted products like alcohol or tobacco. The implementation uses a custom snippet that displays a popup requiring visitors to confirm their age or enter their birthdate.
Key Implementation Details:
- Creates an
age-checksnippet in the theme’s Snippets folder - Sets a cookie (
isAnAdult) that prevents re-prompting for 2 weeks - Supports both simple yes/no verification and date-of-birth picker options
- Includes fallback for users with JavaScript disabled
Common Issues Reported:
- Mobile display problems: Popup appears overly zoomed or as a grey page on mobile devices
- Age calculation bug: Date-of-birth verification incorrectly requires users to be 1 month older than the specified age threshold
- Theme editor interference: Age verification popup blocks the Shopify theme customization preview screen and won’t dismiss when clicking Enter/Exit buttons
- Cookie persistence: Users want options to show the popup on every visit rather than storing the 2-week cookie
Customization Requests:
- Applying verification to specific collections/pages instead of the entire site
- Removing background for SEO purposes (transparent overlay)
- Styling modifications for buttons and text alignment
Important Caveat: This method does not meet FDA regulatory requirements for tobacco/e-cigarette sales and relies on user honesty.
