Buy now, visible always.
Most shoppers never scroll back to the add-to-cart button. Cartylabs fixes that with a sticky bar that stays at the bottom of the screen: product info, variant selected, one-tap checkout. Always visible.
Long product pages bury the buy button.
Modern Shopify product pages are long, packed with images, descriptions, reviews, and FAQs. By the time a shopper finishes reading, the add-to-cart button is far above the fold. Many don't scroll back up.
Cartylabs pins the buy action at the bottom of the screen. The shopper can read the full page without losing access to the purchase step. On mobile, where most Shopify traffic comes from, this is especially impactful.
Sticky cart, done properly.
Smart enough to stay out of the way. Prominent enough to drive clicks.
Sticky add-to-cart bar
A fixed bar at the bottom of product pages shows the product name, selected variant, price, and an "Add to Cart" button, always visible as the shopper scrolls.
Sticky cart icon
A floating cart icon with item count lives in the corner of every page. One tap opens the full cart drawer with no nav menu required.
Variant-aware
The sticky bar reflects the currently selected size, colour, and quantity in real time. Shoppers never need to scroll back to the product form.
Custom placement
Pin the sticky bar to the top or bottom of the viewport. Set z-index, padding, and visibility rules to avoid conflicts with chat widgets or cookie banners.
Hides on cart page
Cartylabs automatically suppresses the sticky bar on the checkout and cart pages to avoid UI clutter at the point of payment.
Mobile first
On mobile, the sticky bar is full-width and thumb-friendly. It hides behind the keyboard when a form is focused and reappears on scroll.
What is a sticky cart on Shopify?
A sticky cart is a persistent UI element, usually a bar at the bottom or top of the screen, that stays visible as the shopper scrolls. It typically shows the product price and an "Add to Cart" button, removing the need to scroll back to the product form.
Is the sticky bar shown on all pages?
The sticky add-to-cart bar is shown on product pages only. The floating cart icon can be shown on all pages and is fully configurable. Both are automatically hidden on the checkout and order confirmation pages.
Will it conflict with my theme's existing sticky elements?
Cartylabs detects common sticky elements (announcement bars, header navs, chat widgets) and adjusts z-index and padding accordingly. You can also set custom offsets in the app dashboard.
Does the sticky cart bar affect page speed?
The sticky bar is a lightweight CSS + JS component loaded asynchronously. It adds less than 5kb to your page weight and has no impact on Core Web Vitals.
Can I style it to match my brand?
Yes. You can customise background colour, text colour, button style, border radius, and font. For advanced customisations, custom CSS is supported.
Is it free?
The sticky cart icon and floating cart are available on all plans including free. The full sticky add-to-cart bar is a Growth plan feature ($9.99/mo).
