Responsive design (mobile-first)
We design responsive design on the mobile-first principle: an interface that works correctly and conveniently on any screens — from phone to desktop, starting design from mobile (where the most traffic and the tightest constraints are). Honestly upfront: responsive design is the base of the modern web, not a 'feature', and it ensures convenience on devices but does NOT guarantee conversion growth by itself; mobile-first is a sensible design approach, not magic; and quality must be checked on real devices, not only in an emulator.
Responsive design (mobile-first) — overview
Responsive design is designing the interface so it displays correctly and is convenient on any screen sizes: phones, tablets, desktops, different orientations. Mobile-first is an approach where design starts with the mobile version (the most space-constrained and often the most visited), then expands to larger screens. It includes flexible grids, responsive typography, breakpoints, convenient touch on mobile, checking on real devices. Honestly about 'base, not a feature': responsiveness today is a standard and necessity, not a premium option. Most traffic is mobile, and a non-responsive site loses these users. Mobile-first is a sensible methodology (start with constraints, then expand), not marketing magic. We do this as a base of quality, honestly. Honestly about 'no conversion guarantee': responsive design ensures the site is CONVENIENT to use on devices (while non-responsive loses mobile users), but by itself it does not guarantee conversion growth — it depends on content, offer, the whole UX. Responsiveness removes the 'inconvenient on a phone' barrier, but it is hygiene, not magical growth. Honestly about device checking: a browser emulator is useful, but real devices behave differently (touch, performance, browser specifics, screen notches). Quality responsiveness is checked on real devices, not only 'in a browser window dragged with the mouse'. Honestly about the link: responsiveness is about layout for screens; mobile-version speed/performance is an adjacent task (optimization); accessibility is a separate aspect (967). Honestly about the effect: it ensures convenience and reach on all devices (a base of quality), but not a direct business-result guarantee. Honestly about access: design/product is needed. An important boundary: this is responsiveness (layout); accessibility — 967; design tokens/system — 961/964. Picture this: instead of 'inconvenient and broken on a phone' — correct convenient operation on any screen. The base price starts from 35,000 ₽ (depends on the number of screens).
Problems we solve
- On a phone the site is inconvenient or breaks — users are lost.
- The design is made only for desktop, mobile suffers.
- No thought-out breakpoints and flexible grids.
- Responsiveness is checked only in a browser, not on devices.

FAQ
Will responsive design raise conversion?
Directly — not guaranteed, honestly. Responsiveness ensures the site is convenient to use on devices (while non-responsive loses mobile users — most of the traffic). It removes the 'inconvenient on a phone' barrier, but conversion depends on content, offer and the whole UX. Responsiveness is a base of quality and hygiene, not magical conversion growth. We honestly separate this.
Is mobile-first a marketing gimmick?
No, honestly: it is a sensible design methodology. You start with the mobile version (the most space-constrained and often the most visited), then expand to larger screens — that way it is easier not to lose the important and account for constraints upfront. It is not magic or a 'feature to sell' but a sound approach to responsiveness we apply as a base of quality.
Is it enough to check responsiveness in a browser?
Not enough, honestly: a browser emulator is useful, but real devices behave differently — touch, performance, browser specifics, screen notches. Quality responsiveness is checked on real devices, not only 'in a browser window dragged with the mouse'. We test on devices so it is genuinely convenient on a phone, not just 'seems to fit'.
