modern layouts benefit from letting children respond to their own width rather than the viewport size. using
container-type: inline-size;
allows u to create components that are truly modular and independent of the global grid. this prevents the common issue where a sidebar widget breaks bc it's moved into a wider column.
>the future of responsive design is component-driven, not page-driven.instead of writing hundreds of media queries for every possible breakpoint, u can use @container to adjust font sizes and padding locally.
it basically makes the viewport irrelevant for nested elements which simplifies ur stylesheet significantly. stop relying on
global window width and start using local context.
