Why CSS Architecture Matters
Understand why unstructured CSS becomes unmaintainable and what good architecture solves.
The CSS Scalability Problem
CSS is easy to write but hard to scale. Without structure, stylesheets become a tangle of overrides, specificity conflicts, and undocumented rules — often described as a "specificity war."
Signs of Unarchitectured CSS
Warning signs your CSS needs architecture:
- Fear of deleting rules because you do not know what they affect
- Frequent use of
!importantto override broken styles - Different pages loading full unrelated stylesheets
- Styles that only work because of a specific HTML structure
