Base44 App Page Layout Broken on Mobile Devices
Your Base44 app looks great on desktop but the layout breaks on mobile devices. Elements overlap, text overflows off the screen, forms are unusable because input fields are too small, and navigation menus don't collapse properly.
Mobile responsiveness is critical since a large percentage of users access web apps on phones and tablets. A broken mobile layout can make your entire app unusable for these users.
The issue may vary across devices: it might look acceptable on a tablet but completely broken on a phone, or it might work on iOS but not Android (or vice versa).
Common Causes
- Fixed-width containers or components that don't adapt to smaller screens
- Tables or data grids that don't scroll horizontally on mobile, causing content to overflow
- Custom CSS that overrides Base44's responsive defaults with fixed pixel values
- Images without responsive sizing that push the layout beyond the viewport width
- Fonts or padding set too large for mobile viewports
How to Fix It
Use your browser's developer tools (F12) to simulate different device sizes and identify which specific components break on smaller screens. Look for elements with fixed widths, oversized fonts, or non-scrolling tables.
If you've added custom CSS, check for any width, font-size, or padding values that use fixed pixels. Replace them with responsive units (%, rem, vw) or add media queries for smaller screens.
For complex layouts that need to work across many device sizes, a developer experienced with responsive design can restructure the layout to be truly mobile-friendly without breaking the desktop view.

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

Get HelpFrequently Asked Questions
Why does my Base44 app look broken on mobile?
Most likely, components or containers have fixed widths that don't adapt to smaller screens. Use your browser's device simulation mode to identify the specific elements causing the issue.
How do I make my Base44 app responsive?
Avoid fixed pixel widths in custom CSS. Use percentage-based widths and test on multiple device sizes using your browser's developer tools.
