Elementor Responsive Layout Cleanup + Container Fixes

I need help fixing responsive layout issues on an existing WordPress/Elementor website. The site is already built. I’m not looking for a redesign, new copy, new branding, or a different layout direction. I need someone who is good with Elementor containers, responsive settings, flexbox, and CSS to clean up visible layout problems across desktop, tablet, and mobile. The main issue is that some sections look fine on one device but not on another. A few tablet/mobile views show things like large gaps, off-centre sections, white strips, or awkward spacing. I want the site cleaned up so it looks stable and professional across all devices. Pages to check/fix: * Home * About * Services * Local Visibility Audit * GBP Improvements * GBP Maintenance * Website Improvements * Contact * Privacy Policy * 404 page Privacy Policy and the 404 page only need layout/responsive fixes if something is visibly wrong. What I need: * diagnose what is causing the responsive issues; * fix the visible layout problems across desktop, tablet, and mobile; * keep the existing copy, images, colours, and general design direction; * avoid installing plugins or making unrelated changes unless approved first; * avoid changing DNS, hosting, email, tracking, or security settings; * provide before/after screenshots for the key fixes; * briefly explain what caused the problems and what I should avoid doing in Elementor in future. Please reply with: * examples of Elementor responsive fixes you’ve done; * how you would approach this without redesigning the whole site; * whether you can work on a staging/duplicate page first; * whether the fixed budget suits this responsive cleanup scope.
