Opacity

Ing v5.1.0, utilitas warna teks digawe karo Sass nggunakake variabel CSS. Iki ngidini owah-owahan warna nyata-wektu tanpa kompilasi lan owah-owahan transparansi alpha dinamis.

Cara kerjane

.text-primaryCoba utilitas standar kita .

.text-primary {
  --bs-text-opacity: 1;
  color: rgba(var(--bs-primary-rgb), var(--bs-text-opacity)) !important;
}

Kita nggunakake versi RGB saka kita --bs-primary(karo Nilai saka 13, 110, 253) variabel CSS lan ditempelake variabel CSS kapindho, --bs-text-opacity, kanggo transparan alpha (karo nilai standar 1thanks kanggo variabel CSS lokal). Tegese kapan wae sampeyan nggunakake saiki, nilai .text-primarydiitung sampeyan yaiku . Variabel CSS lokal ing saben kelas ngindhari masalah warisan supaya conto utilitas ora otomatis duwe transparansi alpha sing diowahi.colorrgba(13, 110, 253, 1).text-*

Tuladha

Kanggo ngganti opacity kasebut, ganti --bs-text-opacityliwat gaya khusus utawa gaya inline.

<div class="text-primary">This is default primary text</div>
<div class="text-primary" style="--bs-text-opacity: .5;">This is 50% opacity primary text</div>

Utawa, pilih salah sawijining .text-opacityutilitas:

<div class="text-primary">This is default primary text</div>
<div class="text-primary text-opacity-75">This is 75% opacity primary text</div>
<div class="text-primary text-opacity-50">This is 50% opacity primary text</div>
<div class="text-primary text-opacity-25">This is 25% opacity primary text</div>

Kekhususan

Kadhangkala kelas kontekstual ora bisa ditrapake amarga kekhususan pamilih liyane. Ing sawetara kasus, solusi sing cukup yaiku mbungkus konten unsur sampeyan ing unsur <div>semantik utawa luwih karo kelas sing dikarepake.

Sass

Saliyane fungsi Sass ing ngisor iki, coba maca babagan properti khusus CSS sing kalebu (alias variabel CSS) kanggo warna lan liya-liyane.

Variabel

Umume colorutilitas digawe saka warna tema, ditugasake maneh saka variabel palet warna umum.

$blue:    #0d6efd;
$indigo:  #6610f2;
$purple:  #6f42c1;
$pink:    #d63384;
$red:     #dc3545;
$orange:  #fd7e14;
$yellow:  #ffc107;
$green:   #198754;
$teal:    #20c997;
$cyan:    #0dcaf0;

$primary:       $blue;
$secondary:     $gray-600;
$success:       $green;
$info:          $cyan;
$warning:       $yellow;
$danger:        $red;
$light:         $gray-100;
$dark:          $gray-900;

Werna werna abu-abu uga kasedhiya, nanging mung subset sing digunakake kanggo ngasilake keperluan apa wae.

$white:    #fff;
$gray-100: #f8f9fa;
$gray-200: #e9ecef;
$gray-300: #dee2e6;
$gray-400: #ced4da;
$gray-500: #adb5bd;
$gray-600: #6c757d;
$gray-700: #495057;
$gray-800: #343a40;
$gray-900: #212529;
$black:    #000;

peta

Werna tema banjur dilebokake ing peta Sass supaya kita bisa ngubengi kanggo ngasilake utilitas, modifier komponen, lan liya-liyane.

$theme-colors: (
  "primary":    $primary,
  "secondary":  $secondary,
  "success":    $success,
  "info":       $info,
  "warning":    $warning,
  "danger":     $danger,
  "light":      $light,
  "dark":       $dark
);

Werna werna abu-abu uga kasedhiya minangka peta Sass. Peta iki ora digunakake kanggo ngasilake utilitas.

$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
);

Werna RGB digawe saka peta Sass sing kapisah:

$theme-colors-rgb: map-loop($theme-colors, to-rgb, "$value");

Lan opacities warna dibangun nganggo peta dhewe sing digunakake dening API utilitas:

$utilities-text: map-merge(
  $utilities-colors,
  (
    "black": to-rgb($black),
    "white": to-rgb($white),
    "body": to-rgb($body-color)
  )
);
$utilities-text-colors: map-loop($utilities-text, rgba-css-var, "$key", "text");

Utilities API

Utilitas warna diumumake ing API keperluan kita ing scss/_utilities.scss. Sinau carane nggunakake API keperluan.

    "color": (
      property: color,
      class: text,
      local-vars: (
        "text-opacity": 1
      ),
      values: map-merge(
        $utilities-text-colors,
        (
          "muted": $text-muted,
          "black-50": rgba($black, .5), // deprecated
          "white-50": rgba($white, .5), // deprecated
          "reset": inherit,
        )
      )
    ),
    "text-opacity": (
      css-var: true,
      class: text-opacity,
      values: (
        25: .25,
        50: .5,
        75: .75,
