Modals and Popups Cut Off on Small Mobile Screens
Modals, popups, and dialog boxes in your Base44 app are unusable on mobile devices. The modal content extends beyond the screen with no way to scroll, action buttons at the bottom are hidden below the viewport, and users can't complete the action the modal was designed for.
Modals are used for critical interactions in Base44 apps: editing records, confirming deletions, viewing details, and filling out forms. When they're broken on mobile, users are stuck and can't complete core workflows.
The issue is especially bad on smaller phones (iPhone SE, older Android devices) and when the device keyboard opens inside a modal form, shrinking the visible area to almost nothing.
Error Messages You Might See
Submit button not visible on mobile modal
Cannot scroll modal content on phone
Modal form fields hidden behind keyboard
Modal extends beyond screen boundaries
Common Causes
- Fixed height exceeding viewport — Modals have a fixed height (e.g., 600px) that exceeds small phone screens (667px or less)
- No internal scrolling — Modal content doesn't scroll, so content below the fold is permanently hidden
- Centered positioning ignores viewport — CSS centering with transform places the modal partially off-screen on short viewports
- Keyboard pushes modal up — When the keyboard opens for form inputs, the modal shifts up and the top is cut off
- Padding consuming too much space — Large padding inside the modal wastes valuable screen real estate on mobile
How to Fix It
- Use max-height: 90vh with overflow-y: auto — Limit modal height to 90% of viewport and make the content scrollable
- Make modals full-screen on mobile — Below 768px, switch modals to full-screen sheets that cover the entire viewport with proper scrolling
- Stick action buttons to the bottom — Use position: sticky; bottom: 0 on the button row so it's always visible regardless of scroll position
- Reduce padding on mobile — Use smaller internal padding (12px instead of 24px) on screens below 640px
- Handle keyboard appearance — Use the Visual Viewport API to adjust modal position when the keyboard opens

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.

I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job.

Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

Get HelpFrequently Asked Questions
Why can't I see the buttons at the bottom of my Base44 modal on mobile?
The modal height exceeds the phone's screen height and the content isn't scrollable. Add max-height: 90vh and overflow-y: auto to the modal, or make buttons sticky at the bottom of the modal.
Should I use modals at all on mobile?
For simple confirmations, modals are fine. For forms with multiple fields, consider navigating to a full-page form on mobile instead of using a modal. This gives users more space and avoids keyboard issues.
