Change the Text variant color on mobile device on Debut Theme

Topic summary

A Shopify store owner using the Debut theme reports that product variant text appears black on a black background on mobile devices, making it invisible to customers.

Initial Solution Attempt:

  • A helper provided CSS code to be added to theme.scss.css using a media query targeting screens with minimum width of 768px
  • The code changes the variant selector text color to red

Complications:

  • The store owner has theme.scss.liquid instead of theme.scss.css
  • The initial fix only worked on desktop, not mobile devices
  • The 768px min-width media query was identified as the likely issue

Revised Solution:

  • Updated CSS code provided using @media (max-width: 768px) instead of min-width
  • This targets smaller screens (mobile devices) specifically

Current Status:

  • Partially resolved: One variant option now displays correctly
  • Issue persists on at least one other product variant selector
  • Store owner provided specific product URLs and screenshots showing remaining visibility problems

Hello There,

  1. In your Shopify Admin go to online store > themes > actions > edit code
  2. Find Asset > theme.scss.css and paste this at the bottom of the file:
@media (min-width: 768px){
select#SingleOptionSelector-0 {
color: red!important;
}
}

I do not have theme.scss.css

I have theme.scss.liquid

I have edited the file I have theme.scss.liquid but It’s change the color on desktop but not on my phone.

Is it about this : min-width: 768px ?

Can we modify it for all the device?

}

The first option is showed. But the second still not showing.
