Header: Full screen vs. Desktop view Fixes

Topic summary

A Shopify store owner using the Wonder theme is experiencing layout inconsistencies between full-screen and desktop views in their header section.

The Issue:

  • Screenshots show the header displays differently at various screen widths
  • The user cannot locate a specific CSS rule that needs removal
  • Store credentials and theme editor link were provided for troubleshooting

Proposed Solution:
A community member (Dan-From-Ryviu) provided custom CSS code to resolve the discrepancy:

  • Sets maximum header width to 1200px
  • Adjusts search label margins and font sizes for screens 1200px and wider
  • Hides certain header elements on larger displays
  • Code should be added via: Sales channels > Online Store > Themes > Customize > Theme settings > Custom CSS
