How to Fix Header Layout Issues in Custom WordPress Themes

Broken navigation? If your WordPress header layout shifts, overlaps, or misbehaves at certain screen sizes, the issue is often buried in custom CSS or JavaScript. In this guide, we’ll show how to diagnose and fix layout conflicts without a theme builder—ideal for fully custom themes or header setups.

Issue Overview

A development site built with a custom theme (no Avada or Elementor) had a persistent layout issue:

  • The navigation “jumped down” below the logo around 1539px screen width.
  • Menu items overlapped or misaligned in tablet view.
  • A grey background appeared in the header when it should have been white.
  • A custom search integration (Ajax Search Pro) may have contributed to the header complexity.

How We Fixed It

🧱 CSS Realignment
  • Removed float styles on the logo causing layout shifts.
  • Repositioned elements to prevent navigation from dropping below the logo.
📱 Breakpoint Optimization
  • Adjusted the breakpoint for the mobile menu to trigger earlier—before the layout could break.
  • Ensured clean transitions across desktop, tablet, and mobile views.
🎨 Header Cleanup
  • Removed leftover styles (like grey backgrounds) and extra spacing.
  • Standardized spacing for logos, buttons, and secondary branding elements.
⚙️ No Code Edits Needed
  • All changes were made using the WordPress Customizer’s Additional CSS field—no direct theme file edits required.

Final Result

The header is now clean, responsive, and consistent across all devices—solving layout breaks, improving user experience, and preserving the custom theme setup.
