Helaian Rujukan SASS

Percuma

Rujukan Sass / SCSS yang boleh dicari dan dicetak — pemboleh ubah, nesting, modul @use, mixin, fungsi, control flow, dan modul terbina dalam. Percuma.

Variables

$primary: #1d6f42;

Declare a variable

$radius: 4px !default;

Set only if not already defined

$theme: dark !global;

Assign to the global scope from inside a block

.box { $w: 10px; width: $w; }

Local variable, scoped to the block

$font-stack: 'Inter', sans-serif;

String / list value

$gap: 8px * 2;

Variables can hold computed values

color: $primary;

Use a variable as a property value

$sizes: 4px, 8px, 16px;

A comma-separated list variable

$config: ('gap': 8px);

A map variable (key/value pairs)

$on: true;

Boolean variable for control flow

Nesting

.card { .title { color: red; } }

Nest a selector inside its parent

.btn { &:hover { opacity: .8; } }

& refers to the parent selector

.btn { &.is-active {} }

Compound parent selector with &

.list { & + & { margin-top: 8px; } }

Adjacent-sibling rule using &

.menu { .dark & { color: #fff; } }

Place & last to prepend a context

.box { font: { size: 14px; weight: 700; } }

Nested properties for a namespace (font-*)

.grid { > .col {} }

Nested child combinator

@media (min-width: 768px) { .col { width: 50%; } }

Nest media queries inside a rule too

.a { color: red; .b & { color: blue; } }

Reorder context by moving &

Partials & modules

_base.scss

Partial file (leading underscore, not compiled alone)

@use 'base';

Load a module (namespaced by file name)

base.$primary;

Access a member through its namespace

@use 'base' as b;

Load a module under a custom namespace

@use 'base' as *;

Load into the global namespace (no prefix)

@use 'theme' with ($primary: #000);

Configure a module's !default variables on load

@forward 'buttons';

Re-export a module from an entrypoint

@forward 'buttons' as btn-*;

Forward members with a prefix

@forward 'src/list' hide list-reset;

Forward but hide specific members

@forward 'config' with ($gap: 4px !default);

Forward and set configurable defaults

Mixins

@mixin reset { margin: 0; padding: 0; }

Define a reusable block of declarations

@include reset;

Apply a mixin

@mixin pad($x) { padding: $x; }

Mixin with an argument

@include pad(8px);

Pass an argument when including

@mixin pad($x: 4px) { padding: $x; }

Argument with a default value

@include pad($x: 12px);

Pass an argument by keyword

@mixin shadow($a...) { box-shadow: $a; }

Arbitrary (variable) arguments

@mixin card { border: 1px solid; @content; }

Accept a @content block

@include card { color: red; }

Pass a block into the mixin's @content

@mixin on-dark { @content; }

Wrap arbitrary rules passed via @content

Functions

@function double($n) { @return $n * 2; }

Define a function that returns a value

width: double(8px);

Call a custom function

@function pad($x: 4px) { @return $x; }

Function with a default argument

@function sum($a, $b) { @return $a + $b; }

Multiple arguments

@function clampn($n) { @if $n < 0 { @return 0; } @return $n; }

Functions may contain control flow

@use 'sass:math';

Import a built-in module for use in functions

@function half($n) { @return math.div($n, 2); }

Use module functions inside your own

@function list-len($l) { @return list.length($l); }

Functions can wrap built-ins

margin: sum(4px, 8px);

Use the returned value as a property value

Operators & math

@use 'sass:math';

Load the math module for division

width: math.div(100%, 3);

Division (math.div, not the deprecated /)

width: 100% - 20px;

Subtraction

margin: 4px + 4px;

Addition

width: 2 * 8px;

Multiplication

$r: 10 % 3;

Modulo (remainder)

@if $a == $b {}

Equality comparison

@if $a >= 768px {}

Greater-than-or-equal comparison

@if $a and $b {}

Logical and

@if not $disabled {}

Logical negation

Control flow

@if $on { display: block; }

Conditional block

@else if $alt { display: flex; }

Additional condition

@else { display: none; }

Fallback branch

@each $c in red, green, blue {}

Iterate over a list

@each $name, $val in $map {}

Iterate over a map's keys and values

@each $k, $v in ('sm': 4px, 'md': 8px) { .#{$k} { gap: $v; } }

Generate rules from a map

@for $i from 1 through 3 {}

Loop inclusive of the end value

@for $i from 0 to 3 {}

Loop exclusive of the end value

@while $i > 0 { $i: $i - 1; }

Loop while a condition holds

Built-in modules

@use 'sass:math'; math.floor(4.7)

Round down to the nearest integer

math.ceil(4.1)

Round up to the nearest integer

math.round(4.5)

Round to the nearest integer

math.percentage(math.div(1, 4))

@use 'sass:string'; string.to-upper-case('hi')

Uppercase a string

string.quote(hello)

Wrap a value in quotes

@use 'sass:color'; color.adjust($c, $lightness: 10%)

.box { @extend %card; }

Inherit a placeholder's styles

.alert { color: red; }

A normal selector to extend

.error { @extend .alert; }

Extend a real selector

.note { @extend .alert !optional; }

!optional: do not error if the target is missing

%btn-base { padding: 8px; }

Share a base across many buttons

.btn-primary { @extend %btn-base; }

Multiple selectors share one rule via @extend

.btn-ghost { @extend %btn-base; }

Each extension is grouped in the output

@include card;

Prefer mixins over @extend for parameterised reuse

Interpolation & misc

.icon-#{$name} { content: ''; }

Interpolate a variable into a selector

width: calc(100% - #{$gap});

Interpolate a Sass value inside calc()

content: '#{$count} items';

Interpolate inside a string

--bs-#{$key}: #{$val};

Build CSS custom properties dynamically

$map: ('sm': 576px, 'md': 768px);

// inline comment

Silent comment (stripped from output)

/* block comment */

Tiada entri sepadan dengan “:q”.

Mengenai Helaian Rujukan SASS

Helaian rujukan Sass / SCSS ini merangkumi prapemproses dari sintaks hingga seni bina: pemboleh ubah, nesting, partial dan modul, mixin, fungsi, operator dan matematik, aliran kawalan, modul terbina dalam, placeholder dan pewarisan, serta interpolation dengan lain-lain perkara.

Ia mencerminkan cara Sass moden ditulis — sistem modul @use dan modul terbina dalam yang dinamakan ruang (namespaced) bersama ciri-ciri klasik — jadi ia sama berguna untuk mengekalkan kod lama @import dan untuk menulis helaian gaya berasaskan modul yang baharu.

Helaian ini percuma dan dipaparkan di sisi klien. Tapis setiap snippet secara langsung dengan kotak carian, lompat ke bahagian dari jadual kandungan yang melekat, klik mana-mana snippet untuk menyalinnya ke dalam helaian gaya anda dan cetak halaman untuk rujukan SCSS bercetak.

Cara menggunakan Helaian Rujukan SASS

Imbas bahagian-bahagian, dari Pemboleh ubah dan Nesting hingga Mixin sampai Modul terbina dalam.
Cari ciri seperti mixin, @use atau map untuk menapis helaian secara langsung.
Lompat ke Aliran kawalan atau Placeholder & pewarisan melalui bar sisi yang melekat.
Klik snippet atau ikon salinnya untuk menyalin SCSS ke dalam helaian gaya anda.
Cetak helaian jika anda lebih suka rujukan kertas semasa merombak gaya.

Soalan lazim

Sepuluh bahagian: pemboleh ubah, nesting, partial dan modul, mixin, fungsi, operator dan matematik, aliran kawalan, modul terbina dalam, placeholder dan pewarisan, serta interpolation ditambah lain-lain perkara.

Ya. Bahagian partial dan modul menunjukkan import berasaskan @use dan namespacing, dan bahagian modul terbina dalam menyenaraikan fungsi standard yang dinamakan ruang yang digunakan dalam Sass moden.

Kedua-duanya ada pada helaian ini: mixin disertakan dengan @include dan boleh menerima argumen, manakala placeholder dilanjutkan dengan @extend dan berkongsi satu selector yang dijana. Bahagian berkaitan menunjukkan sintaks untuk setiap satu.

Ya. Klik mana-mana snippet SCSS atau ikon salin semasa hover dan ia disalin ke papan klip anda dengan pengesahan ringkas.

Ya, sepenuhnya percuma — sisi klien, boleh dicari dan boleh dicetak tanpa akaun.
