Header Search Bar Design Change for Mobile View

Topic summary

A user working with Shopify’s Dawn theme (v12.0) has customized their header search functionality to display as a full search bar instead of an icon on desktop. The issue: This full bar design doesn’t work well on mobile devices.

Desired outcome: Keep the full search bar visible on desktop view while reverting to the traditional search icon on mobile view.

Current status: The user has shared a screenshot showing their current header design and provided their header code (which includes CSS and HTML for various components like search, menu drawer, cart notification, and localization forms). The discussion appears to be seeking technical guidance on implementing responsive CSS or conditional rendering to achieve different search bar presentations across device sizes.

Hello, I am using the dawn theme version 12.0, and I recently edited the header search icon code so that it appears as a full bar. The new full bar design looks great but only for desktop view. I’m wondering if it would be possible to keep the search bar as is for desktop view but to have it return back to a search icon for mobile view. Below I have attached a screenshot of my current header design as well as my header code.
