Max width for iframe in shopify

Store Design

Topic summary

A user is embedding an external web app (shredder-selector.vercel.app) into a Shopify page via iframe and needs it to span the full page width.

Initial Solution:

  • Another user provided CSS code to be added to the theme.liquid file, above the </body> tag
  • This successfully resolved the width issue

New Problem:

  • The iframe and webpage are now scrolling together, creating a confusing user experience
  • The user seeks suggestions to either:
    • Make only the iframe scrollable
    • Remove the footer to improve usability

Status: The discussion remains open with the width issue resolved but a new scrolling behavior problem requiring further assistance.
