Published July 2, 2026
Most people try to use AI for Fix Mobile Layout Breakage with a single vague prompt and get generic results. This guide takes a different approach: 4 targeted stages, from Diagnose the Wall through Prevent Recurrence, each with a prompt that gives the AI exactly the context it needs. The mobile viewport layout is breaking due to styles or layout code that only works on desktop. If left unresolved, this can lead to a poor user experience on mobile devices, potentially driving users away. By following this guide, developers can ensure their applications maintain a responsive design across all devices. Works with ChatGPT, Claude, and Gemini.
Look for layout inconsistencies when viewing the app on mobile devices. Pay attention to any specific error messages or layout shifts that occur.

Then, describe what is currently displayed, highlighting any discrepancies, layout issues, or functionality problems. Conclude with recommendations for adjustments to align the actual behavior with the expected design.
Identify the Responsive Design Constraint
Analyze the mobile layout for responsive design issues and identify the specific rule or constraint that has been violated. Provide the exact clause from the design guidelines that was not adhered to, and explain how this violation impacts the overall user experience on mobile devices. Format your response in a structured way, including the identified issue, the quoted guideline, and a brief analysis of the implications.
Target the specific CSS or layout code that is causing the mobile layout to break. Focus on the styles applied to mobile viewports.
Correct the Mobile CSS Styles
Please review the CSS for the mobile layout in [FILE] at line [LINE]. The original code is as follows: [PASTE]. I would like you to identify the issues with this code and provide a corrected version that resolves the mobile responsiveness problems. Present the corrected CSS code clearly so that it can be easily applied.
Rewrite the Mobile Media Query
Rewrite the media query in the file [FILE] at line [LINE] to ensure it effectively targets mobile devices. The original media query is: [PASTE]. Please provide the updated version that addresses any issues with mobile responsiveness and explain the changes made to improve its functionality.
Scoped Change for Mobile Layout
Identify the issues with the current mobile layout styles in [FILE] at [LINE]. Please provide a detailed analysis of the problems caused by these styles, and then implement the specific change: [PASTE]. Ensure that the updated styles are optimized for mobile responsiveness and explain how this change improves the layout.
Enforce Mobile Layout Format
Please review the mobile layout format in [FILE] at [LINE]. The expected format is [PASTE]. Identify any inconsistencies in the application of this format and suggest specific changes needed to ensure that the mobile layout adheres to the expected standards throughout the document. Provide a summary of your findings and the recommended adjustments.
Verify Mobile Dependencies
Please analyze the file [FILE] for any dependencies related to mobile responsiveness. Identify any missing or outdated dependencies, and provide a detailed list of those that need to be updated or added. Additionally, include recommendations for ensuring all necessary imports are correctly included for optimal mobile performance.
Confirm that the mobile layout is functioning as expected after applying fixes. Look for specific visual cues or layout stability.
Run Mobile Layout Test
Please conduct a mobile layout test to verify that the design is displaying correctly on mobile devices. Specifically, check for any remaining layout shifts, style issues, or elements that do not render as intended. Provide a detailed report outlining any problems found, along with suggestions for fixes and improvements.
Show CSS Diff for Mobile Styles
Please provide a detailed comparison of the CSS changes made specifically for the mobile layout in this project. Highlight the differences between the previous and current versions, focusing on any adjustments that impact mobile responsiveness. Include a summary of the key changes and their intended effects on the mobile user experience.
Replay the Original Mobile Scenario
Please replay the original mobile scenario where the layout broke to verify the resolution. Document any issues that occur during the replay and confirm whether the fixes implemented have resolved these problems. Provide a summary of your findings, including any remaining issues and suggestions for further improvements if necessary.
Check Edge Cases for Mobile Layout
Please analyze the mobile layout for edge cases that could impact its responsiveness. Specifically, evaluate how the layout performs across various screen sizes, including [SCREEN SIZE 1], [SCREEN SIZE 2], and [SCREEN SIZE 3], as well as in both portrait and landscape orientations. Provide a detailed report on any stability issues encountered, along with suggestions for improvements to ensure a consistent user experience.
Confirm Mobile Output State
Please verify the mobile output state in [FILE]. Check that the layout aligns with the expected design specifications, including elements such as font sizes, image placements, and overall responsiveness. Provide a detailed report on any discrepancies found, including screenshots and suggestions for corrections.
Create artefacts that help prevent future mobile layout issues in Bolt. Focus on reusable checks and constraints.
Mobile Layout Validation Prompt
Please create a session-opening constraint for the project focused on mobile layout validation. Use the following format: 'Before any layout changes, verify that all mobile styles adhere to responsive design principles. If any violations are detected, immediately stop the process and notify the developer before proceeding.' Ensure that the constraint is clear and actionable, providing guidance for developers to follow.
Responsive Design Check Template
Create a conversation-starter template for ensuring mobile responsiveness before deployment. Include specific checks such as [CHECK 1] and [CHECK 2] that must be passed. If any issues arise during these checks, instruct the team to halt the deployment process and address the identified problems before proceeding. Format the template clearly for easy reference during discussions.
Mobile Style Specification Message
Draft a project specification message that communicates the following: "All mobile styles must adhere to the guidelines outlined in [SPECIFICATION DOCUMENT]. Any deviations from these guidelines must be documented and receive prior approval from the project manager. Please ensure that all team members are aware of these requirements and understand the importance of compliance to maintain consistency across our mobile platforms.
Mobile Layout Naming Convention
Create a naming convention for mobile layout classes that follows the format 'mobile-[DESCRIPTIVE_NAME]'. Provide examples of at least five different class names that adhere to this convention, explaining the purpose of each class. Additionally, outline the steps to ensure that all new styles are consistently created using this naming convention, including any review processes or documentation that should be implemented.
Self-Check Request for Mobile Layout
Please create a self-check request for agents to ensure that all mobile layouts are fully responsive before deployment. The request should include a checklist of validation checks that must be passed, such as verifying that all styles adapt correctly to different screen sizes, ensuring that images scale appropriately, and confirming that text remains legible on smaller devices. Format the output as a clear, step-by-step guide that agents can follow to validate their mobile layouts.
Mobile layouts can break due to unverified CSS changes that do not account for responsive design. Bolt may not surface these issues until the layout is rendered on mobile devices.
To ensure styles are mobile-friendly, always use media queries that target mobile viewports. Bolt's sandboxed environment may not highlight these issues until the app is tested on actual devices.
If the mobile layout appears fine in the editor, but breaks on devices, check for CSS rules that are not applied correctly in the mobile context. Bolt may not enforce these rules until runtime.
Bolt provides a sandboxed environment that may not accurately reflect mobile behaviors. Always test on actual devices to catch layout issues that Bolt's preview may miss.
Common pitfalls include using fixed widths instead of percentages and neglecting media queries. Bolt's silent failures can lead to these issues going unnoticed until deployment.
