prevent mobile viewport auto-zoom on input focus#5152
Merged
Conversation
Mobile WebKit/Blink engines (such as Safari and Chrome on iOS) automatically zoom in the entire page viewport when a text or numeric input is focused if the computed font-size is strictly less than 16px. This page-level zoom remains locked even after the input is blurred, disrupting the layout and forcing users to manually pinch-to-zoom out to return to normal dimensions. This change fixes the issue globally for the documentation examples and provides educational guidelines for developers copying the patterns: 1. Systemic Styles Guard: Added a scoped style rule in examples.css setting 'font-size: 16px' for all inputs and selects inside floating '.controls' containers. This covers active widgets (e.g. Model Transformations, Post-Processing, variant swapping) across almost all example pages without impacting other standard utility forms. 2. Developer Guidance Tip: Appended an educational "Mobile WebUX Tip" callout under the Model Transformations demo text block inside scenegraph/index.html, explaining the 16px browser threshold quirk to developers who copy-paste the custom markup blocks for their own standalone applications. Verified layout presentation and viewport locking (locked at stable 1.0x scale) under small-screen interaction models. Playwright test suite passes cleanly.
