# Page scrolls horizontally at 375px

`design/horizontal-overflow` · severity **warn** · category Design · detected by `void design` and `void audit`

## Why it matters

Horizontal overflow on a common phone width makes the whole page wobble sideways while scrolling and hides content.

## How to fix it

Find the overflowing element in the evidence and constrain it (max-width: 100%, min-width: 0 on flex/grid children, overflow-wrap: anywhere).

## More design rules

`void design` reports 19 rules in this category. Measured design heuristics from computed styles: font families, type scale, line length, palette and accent sprawl, spacing grid, radius sprawl, dark mode and the tells of generated UI.
