The symptom is specific: wide comparison tables become unreadable on phones. Start with the affected item and identify the decision or input that could produce this behavior.
Find the likely cause
Desktop layout is compressed without a mobile plan.
Treat this as an explanation to verify against the actual work. Look at the input, the relevant decision, and the final result together. If the evidence does not support this diagnosis, investigate the mismatch before applying a convenient but unrelated fix.
Make the targeted correction
Use an accessible responsive presentation that preserves labels and relationships.
Mobile content should preserve the reader's ability to scan, understand, and act within a constrained screen and interaction context.
Check that the repair worked
Compare options on a small screen without losing column meaning.
Repeat the check on the final version that the reader or customer will encounter. An approved draft, a preview, and a published result can differ; the acceptance decision should concern the version people actually use.
Prevent the next related failure
A separate issue to watch for is this: promotional banners cover article text or controls. Adjust placement and dismissal behavior so content remains usable.
Monitor the useful outcome
Track mobile task completion, layout defects, and device-specific support or abandonment patterns.
Keep a short record of the original symptom, the evidence behind the diagnosis, and the result of the acceptance check. That record makes the solution reusable when the same condition appears again, without assuming that every superficially similar problem has the same cause.
