What is a negative effect of over-nesting in Sass?

A Improves code readability

B Makes CSS selectors too specific

C Reduces CSS file size

D Automatically fixes bugs

Over-nesting increases selector specificity, making styles harder to override.

How many levels deep should you ideally nest selectors in Sass?

A 5 or more

B No limit

C 10

D 2 or 3

Keeping nesting to 2 or 3 levels helps maintain readability and simplicity.

Which of these is a better way to write nested selectors in Sass?

A .header { .nav { .item { color: red; } } }

B .header .nav .item .link { color: red; }

C .header .nav .item { color: red; }

D .header { .nav { .item { .link { color: red; } } } }

Writing selectors in one line avoids deep nesting and keeps code simple.

What does over-nesting often cause in the generated CSS?

A More specific selectors

B Shorter selectors

C Less CSS code

D Faster page load

Over-nesting creates very specific selectors that can be hard to override.

Which practice helps avoid over-nesting?

D Writing all styles inline

Clear class names and shallow nesting keep Sass code clean and maintainable.
