Shopify Mass Iframe Title + 3-Per-Row Grid Layout
Click edit pencil to observe code!
This script automatically finds all Shopify Buy Button embeds on the page and adds an accessible iframe title — "Shopify Embed" — to each one.
Use this script if your Shopify Buy Buttons are stacking vertically — it resizes them and arranges them in rows of three. (Place this code in a separate HTML embed after your last Buy Button.)
