- Classes are like assigning all the workers painting the walls to use ash-colored paint, while all the workers painting the windows use white-colored paint.classes apply to multiple elements, making them perfect for shared styles or tasks.Use Classes for Reusability.

- Use lowercase and separate words with hyphen
- IDs are like giving the main door a unique decoration that no other part of the house has. For instance, the front door gets a special design that stands out.IDs are meant for unique elements, as no one else shares their style or purpose.Use IDs for Unique Elements.
- Avoid Repetition
