Mobile First Is Not Optional Anymore
Most of your visitors are on a phone. Design for them first and desktop takes care of itself.
For most of the businesses I build for, the majority of traffic arrives on a phone, usually from a search result, a social link or a WhatsApp message. Designing on a wide desktop screen and squeezing it down afterwards produces sites that technically fit but feel awkward to use.
Mobile first means deciding what matters most when you only have one narrow column. That constraint is useful. It forces you to cut the decorative filler and keep the offer, the proof and the action.
Practical rules I follow: readable body text without zooming, tap targets big enough for a thumb, sticky call or WhatsApp buttons on service sites, forms that are short enough to finish one handed, and images sized for mobile bandwidth.
Navigation matters too. A phone menu should be short and organised by what visitors want, not by your internal structure. Five clear items beat twelve clever ones.
Test on real devices before launch, not just a browser resizer. Real phones reveal the tap, scroll and keyboard issues that a resized desktop window hides.
