Responsive frameworks help developers create websites that look great on all devices without writing excessive custom CSS. Two of the most popular frameworks are Bootstrap and Tailwind CSS. Let’s explore them in detail with examples.
Bootstrap is a component-based CSS framework with pre-designed UI elements, a responsive 12-column grid, and utility classes to speed up development. It helps create consistent, professional layouts quickly.
