Introduction

For years, Media Queries (@media) have been the foundation of responsive web design.

Media queries trigger layout changes based on the viewport width of the browser window. However, in modern component-driven development (using React, Vue, or Web Components), styling components based on the viewport has notable limitations.

For example, if you want to reuse a card component in both a wide main column and a narrow sidebar, media queries cannot detect the space available to the component, causing the layout to break.
