Buy bar
The bar with the product and Add to bag that appears once the product page's buy button scrolls out of view.
Online Store › Themes › Customize › Theme settings › Buy bar
The buy bar appears on product pages once Add to bag scrolls out of view: a full-width bar at the top or bottom of the screen with the product's image and name, its options and Add to bag. Turn it on or off in the product page's Buy action block; the bag uses the same bar for Checkout.

Compact keeps the same bar with a smaller picture and text, and less padding. Its button stays 44px tall, the size a finger needs.
Position
Top sits just under the header.
Picture
Shown on screens 1280px wide and up. Large makes the bar a little taller.

Color scheme
Enable Liquid glass
A frosted, see-through background in the scheme's color that lets the page show softly behind it. When off, the bar is solid.
