Responsive Web Design Basics

Responsive web design is the practice of creating websites that adapt to different screen sizes and devices. It involves using flexible layouts, images, and CSS media queries to ensure a good user experience across desktops, tablets, and smartphones. The key to responsive design is the viewport meta tag, which instructs browsers on how to control the page's dimensions and scaling.

CSS Media Queries

CSS media queries allow developers to apply different styles based on device characteristics, such as screen width, height, or orientation. They use the @media rule to specify conditions under which certain CSS rules should be applied, enabling the creation of adaptive layouts. Media queries can target various device features, including width, height, aspect ratio, and resolution, making them a powerful tool for responsive design.

Responsive Images and Text

Responsive images are crucial for ensuring that visual content looks good on all devices without unnecessary loading times. Techniques for responsive images include using the max-width property, the HTML picture element for art direction, and srcset for resolution switching. Responsive text can be achieved using relative units like em, rem, or viewport units (vw) to ensure readability across different screen sizes.
