Container queries apply CSS styles based on the parent container size rather than the viewport. They are used alongside responsive images and typography scaling to adapt layout elements dynamically to their immediate surroundings.

Flexbox and Grid are both supported for building responsive layouts. Flexbox handles one-dimensional layouts efficiently, while Grid manages two-dimensional structures, allowing you to choose the appropriate system for your specific design needs.

Responsive images serve the right image size based on the device, while typography scaling adjusts text size based on screen size. Both techniques ensure content adapts properly across various screen dimensions without manual breakpoints.
