Find the element causing whole-page sideways scrolling

What to change

Ask the supplier to identify the specific overflow source and contain or redesign it without clipping important information.

A worked example

Illustrative example

A long resource link wraps within its card rather than widening every paragraph on the page beyond the phone screen.

How to check the result

Accept when ordinary content fits the reading width and any necessary horizontal scrolling is limited to a clearly identified component.

A mistake to avoid

Hiding all horizontal overflow can conceal controls or text instead of resolving the component that made the page too wide.

Your action checklist

Use these checks to prepare a discussion with your team or supplier. Tick a check when you have recorded the decision or evidence, rather than when a feature has simply been promised.

Decisions to recordInspect a narrow version of several page types and try moving the whole page sideways. Note where the visible edge extends beyond normal text.Check likely causes such as long addresses, embedded widgets, tables and large images. Ask the supplier to demonstrate which element controls the overflow.Retest after the change with enlarged text and a long field error. Any genuinely wide component should have an understandable local interaction.
