Responsive Web Design uses HTML and CSS to make websites automatically adjust to different screen sizes which provides a good experience on all devices. Setting the viewport with a <meta> tag helps control how the page scales on various screens. Techniques like responsive images, text sizes, and media queries ensure the layout adapts smoothly to different devices.
CSS Frameworks
CSS frameworks like W3.CSS and Bootstrap make it easy to create responsive designs. They offer pre-built styles and layouts optimized for desktop, tablet, and mobile devices. These frameworks automatically adjust page elements based on screen size, simplifying the process of building responsive websites.
CSS Media Queries
CSS media queries let you apply different styles based on a device's screen size, orientation, and resolution. They are commonly used to create responsive designs that adjust to desktops, tablets, and smartphones. This allows for layouts that fit various devices seamlessly.
