Nesting

Nest selectors for readability without creating fragile specificity.

Intermediate 12 min read Lesson 3 of 300 Challenge included

What you will be able to do

Keep nesting to two or three levels.
Use & for hover, focus and modifiers.
Do not nest just to avoid class names.
Prefer flat utility classes where appropriate.

In plain English

Nesting mirrors the DOM but should stay shallow. The parent selector & refers to the outer selector, which is perfect for states and modifiers. Deep nesting creates long selectors and coupling.
