Topic summary
Issue: The store owner wanted to reduce the header’s vertical spacing (raise it closer to the top) in the Streamline theme without changing the logo size.
Context: The shared preview URL was password-protected; the owner provided the password. Clarification established that the target was the header/nav menu height, not the logo size.
Solution: A helper guided adding custom CSS directly in theme.liquid (Shopify’s main layout file). Steps: Online Store > Themes > Actions > Edit code > open theme.liquid, insert CSS before the closing tag, then save. This adjusted the header height independently of the logo.
Artifacts: Screenshots were used to confirm which header area to modify and to show the final result.
Outcome: The change worked as intended; the thread concluded with thanks and a request to mark the solution.
Status: Resolved; no further unanswered questions.
