In the last lesson, you were introduced to DRY (Don’t Repeat Yourself) development concepts, the tokenization of website styling, and the importance of scalability, maintainability, consistency, and so on.

This lesson builds on those concepts by introducing global element styling, BEM classes, utility classes, and the universal selector. I also touch on why ID styling is undesirable in most cases (even though page builders tend to encourage it).

This is a pillar video in the course for three reasons:

1. It corrects most web designers’ biggest mistake with page builders – styling at the ID level.
2. It answers the super common question, “How do I know when to use BEM classes, utility classes, or global styling?”
3. It teaches a proven method for organizing your classes (BEM), which is essential for properly managing a class-first workflow.
