Bounded width
Compact, standard, and wide presets remain inside the available viewport rather than accepting an arbitrary merchant width.
Storefront layout guardrails
Keep your offer readable on smaller screens.
Write your message and choose your design. PrimePopup adjusts the layout for available screen space, stacks side images when needed, and lets longer offers scroll inside the popup.
Built-in layout checks
Room for your message. Access to the controls.
Preview checks help you catch layout problems before publishing. On the storefront, the popup adjusts to the screen and the length of your content.
Bounded height
Long content scrolls inside the popup so the dialog does not extend beyond the usable viewport.
Responsive image stacking
Protected left and right image panels move above the content when the side-by-side minimum width is unavailable.
Horizontal overflow blocking
A composition that would force sideways scrolling is treated as a publish blocker, not a harmless visual suggestion.
Reachable controls
Close, button, coupon, and form actions retain touch-safe sizing and remain reachable while content scrolls.
Reduced motion
Nonessential animation is disabled when the shopper requests reduced motion.
Blocker or warning?
Only invalid storefront states should stop publication.
Publication blockers
Horizontal overflow, invalid destinations, missing required content, unsafe block data, expired timers, or malformed campaign state must be corrected.
Merchant warnings
Internal scrolling, aggressive timing, repeated display, automatic image stacking, or unusually dense content can be valid but deserve attention.
Informational adjustments
Responsive stacking, reduced motion, bounded sizing, and content containment explain what PrimePopup will do automatically.
Guardrails do not promise universal theme compatibility.
PrimePopup isolates its styles and tests representative themes, but custom theme code and other storefront apps can still introduce conflicts. Merchants should preview and verify the published theme.
