Reducing compiled CSS size in SASS - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is one common way to reduce the size of compiled CSS when using Sass?

Use mixins and functions to reuse styles instead of repeating code. This helps keep the CSS smaller and easier to maintain.

intermediate

How does nesting in Sass affect the compiled CSS size?

Nesting can make your Sass code cleaner, but if overused or too deep, it can create very long selectors that increase CSS size. Keep nesting shallow to reduce size.

beginner

What is the benefit of using variables in Sass for reducing CSS size?

Variables let you store values like colors or sizes once and reuse them. This avoids repeating the same values many times, which can reduce the compiled CSS size.

intermediate

Why should you avoid unnecessary @extend in Sass to reduce CSS size?

@extend shares styles between selectors but can create large combined selectors if overused, increasing CSS size. Use it carefully to keep CSS small.

beginner

How does minifying compiled CSS help with size reduction?

Minifying removes spaces, comments, and line breaks from CSS, making the file smaller without changing how it looks in the browser.

Which Sass feature helps reuse style code to reduce compiled CSS size?

A Mixins

B Comments

C Variables

D Placeholders

Mixins let you write reusable blocks of styles, reducing repetition and CSS size.

What happens if you nest selectors too deeply in Sass?

A Sass throws an error

B CSS size decreases

C No effect on CSS size

D CSS size increases

Deep nesting creates long selectors, which increase the compiled CSS size.

Which practice should you avoid to keep compiled CSS size small?

A Using variables

B Using mixins

C Using @extend excessively

D Minifying CSS

@extend can create large combined selectors if overused, increasing CSS size.

What does minifying CSS do?

A Adds comments for clarity

B Removes spaces and comments

C Converts CSS to Sass

D Increases file size

Minifying removes spaces, comments, and line breaks to reduce file size.

How do variables help reduce compiled CSS size?

A By storing values once and reusing them

B By nesting deeply

C By creating new selectors

D By repeating values

Variables store values once, avoiding repetition and reducing CSS size.
