What is mobile responsiveness? It’s the essential practice of designing a website that fluidly adapts its layout and functionality to provide an optimal viewing experience across all devices, from desktops to smartphones.

For ecommerce operators, neglecting mobile responsiveness means alienating a significant portion of potential customers, as a clunky mobile experience directly impacts conversion rates and user satisfaction [2].
