Changing Field Inputs to Underline Instead of Boxes

Topic summary

A user wants to replace boxed input fields with underlined inputs across their Shopify store.

Current Status:

  • Successfully implemented underlined styling for newsletter footer fields using custom CSS in base.css
  • The CSS solution removes box-shadow and adds a 1px solid black bottom border to .newsletter-form__field-wrapper .field:after

Remaining Tasks:
The user now seeks to apply the same underline styling to:

  • Account fields (create account and login pages)
  • Search page and search bar
  • Custom liquid sections

Technical Approach:
Modification involves editing the theme’s base.css file through Online Store → Themes → Edit Code, with CSS targeting specific field wrapper classes.

The discussion remains open as the user awaits guidance on extending this styling to additional input fields throughout the store.

2 . Find the base.css file and paste this code at the bottom of the file:

Code :

.newsletter-form__field-wrapper .field:after{
    box-shadow: none !important;
    border-bottom: 1px solid black;
}

3 : Save and hope you get the result like the image:

Hi,

Thanks so much this worked! My next question is, how do I do the same with the following:

  • Customer Account fields (to create an account & to login)

  • Search page (& bar if possible)

Thank you again!
