Let visitors read and close a long dialog

What to change

Ask the supplier to preserve complete reading and action access when dialog content is longer than the available viewport.

A worked example

Illustrative example

A visitor reads a long explanation in a panel, reaches its final confirmation control and can still return to the beginning without moving the page behind it.

How to check the result

Accept when all dialog information and actions are reachable with a coherent scroll experience at the agreed supported sizes.

A mistake to avoid

Setting a maximum height without arranging a usable overflow area can simply cut off the content that no longer fits.

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 recordOpen the longest dialog at high zoom and on a short phone viewport. Scroll to its end and identify whether the panel or background is moving.Reach the final action using a keyboard. Check the focused control becomes visible and any fixed header or footer does not conceal it.Ask the supplier to demonstrate the effect of additional error text or expanded help inside the dialog. The scroll behaviour should remain clear.
