Sometimes you want to apply the same style to many elements.
Grouping selectors help you do this easily and cleanly.
What Is a Grouping Selector
A grouping selector allows you to combine multiple selectors and apply the same styles to all of them.
How Grouping Selectors Work
You write multiple selectors separated by commas.
Now all headings share the same color.
Why Use Grouping Selectors
Grouping selectors help you:
- Reduce repeated code
- Keep CSS shorter
- Make updates easier
Without Grouping
You would have to write the same style many times.
This works, but it is longer and harder to maintain.
With Grouping
One rule can replace all of that.
Much cleaner and easier to update.
Grouping Different Types of Selectors
You can group:
- Element selectors
- Class selectors
- ID selectors
All these elements now share the same style.
Why This Matters for Jobs
Professional developers write efficient CSS.
Grouping selectors helps keep projects clean and maintainable.
Common Beginner Mistakes
- Forgetting commas between selectors
