Ampitahao ny dikany amin'ny alàlan'ny background-colorasio haingo misy gradient.
Loko ambadika
Mitovy amin'ny kilasy lokon'ny lahatsoratra contextual, apetraho amin'ny kilasy contextual ny lafin'ny singa iray. Tsy napetrakacolor ny kojakoja fototra , ka amin'ny tranga sasany dia te hampiasa .text-* fitaovana miloko ianao .
<div class="p-3 mb-2 bg-primary text-white">.bg-primary</div>
<div class="p-3 mb-2 bg-secondary text-white">.bg-secondary</div>
<div class="p-3 mb-2 bg-success text-white">.bg-success</div>

Amin'ny fampidirana .bg-gradientkilasy iray dia ampiana gradient tsipika ho sary lafika amin'ny lamosina. Ity gradient ity dia manomboka amin'ny fotsy semi-mangarahara izay manjavona hatrany ambany.
Mila gradient amin'ny CSS mahazatra anao ve ianao? Ampio fotsiny background-image: var(--bs-gradient);.
Sass
Ho fanampin'ity fampiasa Sass manaraka ity, diniho ny famakiana momba ny fanananay manokana CSS nampidirina (aka CSS variables) ho an'ny loko sy ny maro hafa.
hiovaova
Ny ankamaroan'ny background-colorfitaovana ampiasaina dia novokarin'ny loko loha-hevitray, naverina avy amin'ny fari-piainan'ny palette miloko.
$blue: #0d6efd;
$indigo: #6610f2;
$purple: #6f42c1;
$pink: #d63384;
$red: #dc3545;
$orange: #fd7e14;
$yellow: #ffc107;
$green: #198754;

$danger: $red;
$light: $gray-100;
$dark: $gray-900;
$gradient: linear-gradient(180deg, rgba($white, .15), rgba($white, 0));
Misy ihany koa ny loko grayscale, saingy ampahany kely ihany no ampiasaina hamokarana fitaovana rehetra.
$white: #fff;
$gray-100: #f8f9fa;
$gray-200: #e9ecef;
$gray-300: #dee2e6;
$gray-400: #ced4da;
$gray-500: #adb5bd;

$gray-700: #495057;
$gray-800: #343a40;
$gray-900: #212529;
$black: #000;
Sarintany
Apetraka ao amin'ny sarintany Sass avy eo ny lokon'ny lohahevitra mba ahafahantsika mihodinkodina eo amboniny mba hamoronana ny kojakojantsika, ny mpanova singa, sy ny maro hafa.
$theme-colors: (
"primary": $primary,
"secondary": $secondary,
"success": $success,
"info": $info,
"warning": $warning,
"danger": $danger,
"light": $light,
"dark": $dark
);
Ny loko grayscale dia azo alaina amin'ny sarintany Sass. Ity sari-tany ity dia tsy ampiasaina hamoronana fitaovana.
$grays: (
"100": $gray-100,
"200": $gray-200,
"300": $gray-300,
"400": $gray-400,
"500": $gray-500,
"600": $gray-600,
"700": $gray-700,
"800": $gray-800,
"900": $gray-900
);
Mixins
Tsy misy mixins ampiasaina hamoronana kojakoja fototra , fa manana mixins fanampiny izahay ho an'ny toe-javatra hafa izay tianao hamoronana ny gradients anao manokana.
@mixin gradient-bg($color: null) {
background-color: $color;
@if $enable-gradients {
background-image: var(--#{$variable-prefix}gradient);
}
}
// Horizontal gradient, from left to right
//
// Creates two color stops, start and end, by specifying a color and position for each color stop.
@mixin gradient-x($start-color: $gray-700, $end-color: $gray-800, $start-percent: 0%, $end-percent: 100%) {
background-image: linear-gradient(to right, $start-color $start-percent, $end-color $end-percent);
}
// Vertical gradient, from top to bottom
//
// Creates two color stops, start and end, by specifying a color and position for each color stop.
@mixin gradient-y($start-color: $gray-700, $end-color: $gray-800, $start-percent: null, $end-percent: null) {
background-image: linear-gradient(to bottom, $start-color $start-percent, $end-color $end-percent);
}
@mixin gradient-directional($start-color: $gray-700, $end-color: $gray-800, $deg: 45deg) {
background-image: linear-gradient($deg, $start-color, $end-color);
}
@mixin gradient-x-three-colors($start-color: $blue, $mid-color: $purple, $color-stop: 50%, $end-color: $red) {
background-image: linear-gradient(to right, $start-color, $mid-color $color-stop, $end-color);
}
@mixin gradient-y-three-colors($start-color: $blue, $mid-color: $purple, $color-stop: 50%, $end-color: $red) {
background-image: linear-gradient($start-color, $mid-color $color-stop, $end-color);
}
@mixin gradient-radial($inner-color: $gray-700, $outer-color: $gray-800) {
background-image: radial-gradient(circle, $inner-color, $outer-color);
}
@mixin gradient-striped($color: rgba($white, .15), $angle: 45deg) {
background-image: linear-gradient($angle, $color 25%, transparent 25%, transparent 50%, $color 50%, $color 75%, transparent 75%, transparent);
}
