CSS

While responsive design is necessary to accommodate different screen sizes, its successful implementation remains challenging. Developers must balance complexity and functionality across diverse device types and screen resolutions.

Using CSS `@import` rules creates additional sequential HTTP requests and render-blocking behavior that delays page rendering. Each imported file is fetched sequentially rather than in parallel, degrading frontend performance.

Seemingly minor design adjustments often trigger extensive changes in the codebase, particularly when dealing with tightly coupled CSS or JavaScript frameworks.
