Conclusion

Responsive web design in Europe now goes well beyond making a desktop layout fit a smaller screen. Strong projects account for navigation, readability, performance, accessibility, interaction patterns, and the way functionality changes across phones, tablets, and larger displays.

The right choice depends heavily on the type of project. A straightforward business website may call for a design-focused team, while a SaaS platform, customer portal, marketplace, or complex web application often benefits from deeper frontend and backend expertise. Looking at relevant project experience, UX capabilities, technical skills, testing practices, and ongoing support provides a much clearer basis for comparison than design portfolios alone.
