The page scrolls sideways on mobile

01The problem

Content is wider than the mobile viewport, so the layout can be dragged horizontally.

Horizontal overflow hides content off-screen and makes vertical scrolling unreliable. It is read as a defect, and it undermines trust in everything else on the page.

02How Leakly detects it

A structural fact counted in the rendered page, or a measurement against a threshold. Confidence ceiling for this detector family: 96%.

03Proof required

• Elements located in the rendered page, with their position and size.
• A measured number, with its unit and the threshold it crosses.

Without it, the finding is not reported.

04How to fix it

Remove the horizontal overflow.

1. Find the element wider than the viewport and constrain it.
2. Check tables, code blocks and fixed-width images first — they are the usual cause.

Each audit that finds this leak includes the exact element, a suggested change and, for copy, a rewrite you can paste.
