What is CSS Modules?
A CSS approach that automatically scopes class names to a specific component to prevent naming conflicts.
Why It Matters
CSS Modules let you use simple class names like .button without worrying about clashes with other components.
Real-World Example
Two components can both use a .title class, and CSS Modules ensures they do not conflict.
“Understanding terms like CSS Modules matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
