Why a responsive website is essential in 2025?

What is a responsive website?

A responsive (adaptive) website automatically adjusts to the screen size it is viewed on: smartphone, tablet, laptop or desktop.

Responsive design uses CSS techniques (media queries, flexible grids, fluid images) to provide an optimal experience on any device.
