What is a characteristic of responsive web design?

Responsive web design is characterized by its ability to adapt the layout of a website to suit different screen sizes and devices. This approach ensures that users have an optimal viewing experience, regardless of whether they are accessing the site from a desktop, tablet, or smartphone. The flexible grid layout often employed in responsive design allows for elements to resize, reposition, or rearrange according to the dimensions of the user's device.

This adaptability enhances usability and accessibility by providing a seamless interaction with the content, which is essential in today's diverse digital landscape. The other options either suggest outdated practices or misunderstand the principles of responsive design, which fundamentally aims to create a single, versatile website that serves all devices rather than separate ones.
