Step-by-step explanation:
False: Responsive design does not rely on predefined screen sizes.
Responsive design is an approach to web design that allows a website to adapt its layout and functionality based on the size of the user's screen. Instead of relying on specific screen sizes, responsive design uses fluid grids, flexible images, and CSS media queries to ensure that the content looks and functions well on a variety of devices, from smartphones to tablets to desktop computers.
For example, a responsive website may display a single column layout on a smartphone and switch to a multi-column layout on a larger tablet or desktop screen. By using a responsive design, websites can provide an optimal viewing experience for users across different devices and screen sizes.
