What does "responsive web design" refer to?

Responsive web design refers to the approach in web development where websites are crafted to adapt seamlessly to various screen sizes and orientations. This means that whether a user is accessing a website on a desktop computer, tablet, or smartphone, the layout and content of the site will adjust accordingly to provide an optimal viewing experience. Key techniques used in responsive web design include flexible grids and layouts, as well as media queries that allow different CSS styles to be applied based on the characteristics of the device being used.

This adaptability is crucial in today's web environment, given the diversity of devices used to access the internet. By ensuring that sites are responsive, developers can improve usability and accessibility, leading to a better user experience across all platforms.
