My Wix Studio site is already designed, but the global header has become unpredictable. Depending on the breakpoint the grid row flickers between heights, sometimes compressing, sometimes expanding, and it behaves differently on the Home page, Product pages, About Us, and even the Contact page. I need the header cleaned up, not redesigned. Across Mobile, Tablet, and Desktop breakpoints I want a single master header component that: • Sits in a clean, fixed-row grid (no proportional scaling) • Holds 110 px on Desktop and 88 px on Mobile—identical on every page • Remains untouched by changes I make in other breakpoints • Shrinks only on Desktop, triggered at the exact scroll position we agree on • Leaves Mobile and Tablet scroll behavior completely unchanged You’ll jump straight into Wix Studio, adjust the grid/stack settings, pin the numeric heights, and verify the fix on all named pages so the layout no longer shifts. When you hand it back I’ll review on the three breakpoints; once the header is pixel-consistent everywhere and the shrink effect fires precisely where specified, the job is done.
