Mobile Keyboard Pushing Content Off Screen in Lovable
When users tap on an input field in your Lovable app on mobile, the on-screen keyboard pushes content off the screen, hides the input field behind the keyboard, or causes the entire layout to shift and break.
This is extremely frustrating for users trying to fill out forms, write messages, or search. They can't see what they're typing, buttons become unreachable, and the app feels completely broken during text input.
The problem is particularly bad on iOS where the keyboard behavior differs significantly from Android, and fixed-position elements (headers, footers, CTAs) cause additional complications.
Error Messages You Might See
Common Causes
- Fixed positioning with keyboard — Fixed-position elements (headers, footers, floating buttons) don't adjust when the keyboard opens
- 100vh height issue — Using 100vh for layout height doesn't account for the keyboard, causing content to be hidden behind it
- Missing scrollIntoView — The focused input doesn't scroll into view above the keyboard
- iOS visual viewport issues — iOS handles the viewport differently when the keyboard appears, especially in PWA mode
How to Fix It
- Use dvh instead of vh — Replace height: 100vh with height: 100dvh which accounts for dynamic viewport changes including keyboard
- Scroll input into view — Add a focus event listener that scrolls the input into the visible area: element.scrollIntoView({ behavior: 'smooth', block: 'center' })
- Avoid fixed positioning on forms — Use sticky positioning or make the form content scrollable instead of fixed
- Use visualViewport API — Listen to the visualViewport resize event to adjust layout when the keyboard appears
- Test on real devices — Keyboard behavior varies significantly between iOS and Android and can't be fully simulated in DevTools

I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

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.

Why does this only happen on iOS?
iOS handles the virtual keyboard differently than Android. On iOS, the keyboard overlays the viewport without resizing it, while Android typically resizes the viewport. This means iOS requires special handling with the visualViewport API.
What is dvh?
dvh stands for dynamic viewport height. Unlike vh which is fixed to the initial viewport size, dvh updates when the viewport changes — like when a mobile keyboard appears or disappears.
