Responsive Web Design Agency · Mobile-First, Performance-Led, Accessible

Responsive design done as engineering — mobile-first, performance-budgeted, and accessibility-checked at every breakpoint. We don't design at 1440 and squeeze it down; we design at 360 and let the layout earn its desktop space.

Why HXRL

Our point of view

On the African continent, mobile-first isn't a methodology — it's the only way that survives contact with users. We design for low-bandwidth and modest-CPU devices first because that's where the audience is.

Outcome

A site that works on a 360px Android Go device on a 3G connection — not just on the team's MacBook in office Wi-Fi.

FAQ

Questions clients actually ask

Drawn from sales calls, not SEO filler. Want a question added? Drop it in the form on this page — we update from real enquiries.

Tailwind or vanilla CSS?+

Tailwind when team velocity and design-token discipline matter. Vanilla CSS when the design has unique needs and the team prefers explicit. Both ship in production.

Container queries — production-ready?+

Yes — modern browser support is solid in 2026. We use them where component-level layout independence justifies it.

How do you handle Core Web Vitals?+

Designed in, not bolted on. LCP, INP, and CLS budgets per page in CI; release gates on regression.

Print stylesheets — do you do those?+

Yes — when they're commercially relevant (invoices, statements, regulated documents). Mostly not.
