Mobile Responsive Design Broken on Replit
App displays incorrectly on mobile devices with layout breaking, text too small, or elements overlapping. Responsive design isn't working.
Missing viewport meta tag or CSS media queries cause mobile rendering issues.
Common Causes
- Missing viewport meta tag in HTML head
- Fixed width CSS instead of flexible
- No CSS media queries for mobile breakpoints
- CSS not loaded on mobile due to caching
- Images not responsive (missing max-width: 100%)
How to Fix It
Add to all HTML templates. Use CSS media queries or Tailwind/Bootstrap for responsive design. Set img { max-width: 100%; } for images. Test with Chrome DevTools mobile emulation. Use flexible units (%, em, rem) instead of fixed pixels.

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

What's the viewport meta tag?
<meta name="viewport" content="width=device-width, initial-scale=1"> - tells mobile browser to use device width
Should I use Bootstrap or Tailwind?
Both work. Tailwind is lighter, Bootstrap has more components. Choose based on project needs
