Responsive Design
What is it?
Responsive design is an approach to web development that ensures websites look and function well on all devices and screen sizes, from mobile phones to large desktop monitors. It uses flexible grids, fluid images, and CSS media queries to adapt the layout and content presentation based on the viewport dimensions, providing optimal user experience everywhere.
Practical example
A responsive website might display a three-column layout on desktop, switch to two columns on tablets using @media (max-width: 1024px), and stack everything in a single column on mobile with @media (max-width: 768px). The navigation transforms from a horizontal menu to a hamburger menu, and images use max-width: 100% to scale down proportionally.
