AI website buttons not working on mobile: trace touch, layers and handlers

A worked example: where the task becomes difficult

A fictional landing page has working desktop navigation but its phone menu and signup button do nothing. An invisible full-screen transition layer remains above the page after loading. The buttons look enabled, so the visitor receives no explanation. Reproduce on a controlled mobile viewport, inspect the element receiving the tap and compare it with the visible button. Do not assume every mobile failure is a touch-event problem.

Decisions to make before implementation

Separate hit testing, application state and network behavior. A control can receive the tap but return early because a loading flag never resets. A link may navigate to a fragment with no corresponding section. Use actual semantic buttons and links where appropriate instead of duplicating click and touch handlers that can trigger an operation twice. Check keyboard access as well as the mobile tap path.

A practical sequence for the work

Use the sequence below as a task boundary, not as a claim that the example has been executed. Work with approved inputs and the project’s actual architecture. If a required integration or permission is unavailable, keep that stage visibly incomplete rather than generating a plausible substitute result.

• Reproduce one failed control and inspect the element above its visible position.
• Check computed positioning, pointer behavior, dialog layers and disabled state.
• Trace handler execution and the resulting navigation or request.
• Repair the supported cause and verify unrelated mobile controls and keyboard behavior.

A detailed brief you can adapt for your agent

Replace the illustrative context with your approved facts and controlled inputs. Keep the stated boundaries when adapting the brief. The expected deliverable matters more than a particular tool name: ask for an explanation grounded in the inspected material and evidence for the requested outcome.

Investigate the unresponsive mobile menu and signup CTA. Trace the topmost tap target, control state and first relevant client error. Preserve semantic controls and repair the supported layer or handler issue. Do not globally disable modal pointer handling. Verify tap, repeated modal closure and keyboard activation; report the actual cause.

Failure modes that an attractive preview can hide

Setting every overlay to ignore pointer events can make dialogs impossible to use or expose the page beneath a modal. Fix the lifecycle of the layer that should have closed. Avoid installing a touch library simply to conceal a client exception. Test scrolling and opening another modal afterward so the repair does not leave body scrolling or focus permanently locked.

Acceptance checks and the evidence to retain

Keep the failed control, responsible layer or handler, repaired lifecycle and retest results. A screenshot proves appearance; retain interaction evidence for the behavior that was broken.
