In real projects, CSS is not written just to look good but to work well on all devices.
This lesson shows how to build a small responsive layout using clean structure, reusable classes, and best practices.
You will apply everything learned so far in a real project style approach.
This layout starts with a mobile design.
On larger screens, it switches to a three column grid automatically.
Utility classes help apply small changes without writing new CSS.
They keep the stylesheet clean and reusable.
This shows how components and utilities work together.
The same card design can be reused on multiple pages.
Best practices used here
- Mobile first layout
- Reusable components
- Utility classes
- Simple selectors
- Clean file structure
Grouping related styles makes your CSS easier to scale.
This is how professional projects stay organized.
Practice task
