CSS Specificity Mastery
The Complete Guide to Writing Predictable, Maintainable Stylesheets
Imagine opening your stylesheet and instantly knowing why a style isn't applying—no more digging through dozens of rules or adding !important as a band-aid fix. CSS specificity is the foundation of predictable, maintainable stylesheets, yet many developers treat it as an afterthought. This guide walks you through the complete specificity system: how it's calculated, why it matters, and how to use it strategically in real-world projects. You'll learn to recognize specificity problems before they happen, refactor existing code without breaking layouts, and build design systems that scale. Whether you're working with vanilla CSS, preprocessors, or modern frameworks, you'll discover practical techniques that eliminate style conflicts and make your code easier for others to understand and modify. Stop fighting the cascade. Start mastering it.
