Responsive design is a web development approach that creates dynamic changes to the appearance of a website, depending on the screen size and orientation of the device being used to view it. It is an essential part of creating websites that are optimized for mobile devices, as well as for desktop and laptop computers. In Drupal, responsive design is achieved through the use of themes and modules that are designed to adjust the layout of a website based on the size of the device being used to view it.

Responsive design is based on the concept of “fluid grids”, which are grids that adjust to the size of the device being used to view the website. This allows the website to be displayed in a way that is optimized for the device, ensuring that the user experience is consistent across all devices. Responsive design also uses media queries, which are code snippets that allow the website to detect the size of the device and adjust the layout accordingly.

Additionally, Drupal’s core codebase includes a number of features that are designed to make it easier to create responsive websites.
