Debut Theme - How do I change just one of the main menu items to a different color?

Topic summary

A Shopify store owner wants to change the color of their “SALE” menu item to red in the Debut theme.

Initial Solution Attempt:

  • PageFly-Henry provided CSS code to be added to theme.liquid file
  • Solution failed because the user is on Debut theme, not Dawn theme

Working Solution:
BSS-Commerce provided updated instructions:

  • Navigate to Online Store → Themes → Edit code
  • Add CSS code to the end of theme.css file targeting the last menu item
  • Code uses .site-nav.list--inline.site-centered--nav li:last-child selector with background-color: red

Current Status:

  • Solution works successfully on desktop
  • Issue remains: the red color is not visible on mobile devices
  • User is seeking a fix for mobile display

Hi @stainlessbags

This is Henry from PageFly - Landing Page Builder App

You can try this code by following these steps:

Step 1: Go to Online Store->Theme->Edit code.

Step 2: Search file theme.liquid

Step 3: paste bellow code in tag → save.

[href="/collections/sale-1"] span { color: red !important; }

Hope that my solution works for you.

Best regards,

Henry | PageFly
