Project details

You will get one existing website or web app section adjusted for mobile screens.

A React expert from my team will review the selected section, identify what breaks on smaller screens, and update the layout so it looks cleaner and works better on mobile devices.

This package is focused on one specific section, such as a hero block, pricing section, feature block, CTA, form section, card grid, testimonial block, or content area.

This is not a full website responsive redesign. It covers one clear section with provided code access, screenshot, page link, and expected result.

This package is a good fit if your desktop layout looks fine, but one section breaks, overflows, looks cramped, or feels unpolished on mobile.
Programming Languages
JavaScript, TypeScript
Coding Expertise
Cross Browser & Device Compatibility, Localization, Performance Optimization
