Issue: The OP needed to reduce the header height in Shopify’s Dawn theme v15. They had already trimmed the logo and set top/bottom padding to zero, but the header remained too tall.
Requests: Responders asked for the store URL and password to investigate.
Solution provided: Guidance to edit theme files—Online Store > Edit Code > open theme.liquid—and insert custom code just above the closing tag to reduce header height. A screenshot showed the result with a slimmer header.
Note: The exact code snippet isn’t visible in the thread extract, which may be central for replication.
Outcome: The OP confirmed the fix worked (“All sorted”). No further issues or debates were raised. The discussion appears resolved.
