Responsive means usable, not just smaller
A layout can fit a phone and still be difficult to use. Navigation may consume the entire screen, a button may be hidden by a fixed banner, or a form may require unnecessary typing. Judge responsiveness by whether someone can finish the task comfortably, not only whether the page has horizontal overflow.
Test content at awkward widths
Review a narrow phone, a wider phone, a tablet and a desktop. Resize between those points too. Long service names, translated labels and unusually large prices expose fragile layouts. Use real content rather than short placeholders, and check that zooming the page does not hide controls or truncate important information.
Walk through the enquiry journey
Open the menu, read a service, start an enquiry, correct a mistake and submit. Check whether the keyboard covers the active field. Make field labels visible even after typing. Use a clear error near the field and preserve the information already entered. A customer should not need to start again because one value was invalid.
Check interaction beyond touch
Navigate with a keyboard and confirm that focus is visible. Avoid features that require hovering to reveal essential content. If you use a carousel, provide understandable controls and a way to pause it. Keep phone numbers and email addresses easy to select or activate without accidentally opening another element.
Record issues by business impact
A blocked submission is more urgent than an imperfect decorative alignment. Keep a short log containing device, browser, steps, expected result and actual result. After fixing an issue, repeat the full journey. Use browser simulations for coverage, then check at least the devices your customers actually use before declaring the experience ready.
