Iiklasi ezisisiseko

Izinto zeBootstrap zakhiwe ubukhulu becala nge-base-modifier nomenclature. Sidibanisa iipropathi ezininzi ekwabelwana ngazo kudidi lwesiseko, njenge .btn, kwaye emva koko sidibanise izimbo zohlobo ngalunye ngokwahlukileyo kwiiklasi zesilungisi, njenge .btn-primaryokanye .btn-success.

Ukwakha iiklasi zethu zesilungisi, sisebenzisa iilophu ze-Sass @eachukuphindaphinda imephu ye-Sass. Oku kuluncedo kakhulu ekuveliseni ukwahluka kwecandelo ngokwethu $theme-colorskunye nokudala iiyantlukwano eziphendulayo kwindawo nganye yoqhawulo. Njengoko usenza ngokwezifiso ezi mephu ze-Sass kwaye uphinda uhlanganise, uya kubona ngokuzenzekelayo utshintsho lwakho lubonakaliswe kwezi lophu.

Jonga iimephu zethu ze-Sass kunye ne-loops amaxwebhu malunga nendlela yokwenza ezi lophu kunye nokwandisa indlela ye-Bootstrap yokuguqula isiseko kwikhowudi yakho.

Izilungisi

Uninzi lwamacandelo e-Bootstrap akhiwe ngendlela yeklasi ye-modifier. Oku kuthetha ukuba ubuninzi besimbo buqulethwe kudidi olusisiseko (umzekelo, .btn) ngelixa ulwahlulo lwesimbo luvalelwe kwiiklasi zesilungisi (umzekelo, .btn-danger). Ezi klasi zesilungisi zakhiwe $theme-colorskwimephu ukwenza inani kunye negama leeklasi zethu zesilungisi.

Nantsi imizekelo emibini yendlela esijika ngayo phezu kwemephu $theme-colorsukwenza izilungisi kwizixhobo ..alert.list-group

// Generate contextual modifier classes for colorizing the alert.

@each $state, $value in $theme-colors {
  $alert-background: shift-color($value, $alert-bg-scale);
  $alert-border: shift-color($value, $alert-border-scale);
  $alert-color: shift-color($value, $alert-color-scale);

  @if (contrast-ratio($alert-background, $alert-color) < $min-contrast-ratio) {
    $alert-color: mix($value, color-contrast($alert-background), abs($alert-color-scale));
  }
  .alert-#{$state} {
    @include alert-variant($alert-background, $alert-border, $alert-color);
  }
}

// List group contextual variants
//
// Add modifier classes to change text and background color on individual items.
// Organizationally, this must come after the `:hover` states.

@each $state, $value in $theme-colors {
  $list-group-variant-bg: shift-color($value, $list-group-item-bg-scale);
  $list-group-variant-color: shift-color($value, $list-group-item-color-scale);
  @if (contrast-ratio($list-group-variant-bg, $list-group-variant-color) < $min-contrast-ratio) {
    $list-group-variant-color: mix($value, color-contrast($list-group-variant-bg), abs($list-group-item-color-scale));
  }

  @include list-group-item-variant($state, $list-group-variant-bg, $list-group-variant-color);
}

Ukusabela

Ezi lophu zeSass aziphelelanga kwiimephu zemibala, nazo. Unokwenza kwakhona ulwahlulo oluphendulayo lwamacandelo akho. Thatha umzekelo ukulungelelaniswa kwethu okuphendulayo kokwehla apho sixuba i- @eachloop $grid-breakpointsyemephu ye-Sass kunye nombuzo weendaba ezibandakanya.

// We deliberately hardcode the `bs-` prefix because we check
// this custom property in JS to determine Popper's positioning

@each $breakpoint in map-keys($grid-breakpoints) {
  @include media-breakpoint-up($breakpoint) {
    $infix: breakpoint-infix($breakpoint, $grid-breakpoints);

    .dropdown-menu#{$infix}-start {
      --bs-position: start;

      &[data-bs-popper] {
        right: auto;
        left: 0;
      }
    }

    .dropdown-menu#{$infix}-end {
      --bs-position: end;

      &[data-bs-popper] {
        right: 0;
        left: auto;
      }
    }
  }
}

Ukuba ulungisa eyakho $grid-breakpoints, utshintsho lwakho luya kusebenza kuzo zonke iilophu eziphinda-phindayo phezu kwaloo mephu.

$grid-breakpoints: (
  xs: 0,
  sm: 576px,
  md: 768px,
  lg: 992px,
  xl: 1200px,
  xxl: 1400px
);

Ukwenza eyakho

Siyakukhuthaza ukuba wamkele ezi zikhokelo xa usakha ngeBootstrap ukwenza ezakho izinto. Siye sayandisa le ndlela ngokwethu kumacandelo esiko kumaxwebhu ethu kunye nemizekelo. Amacandelo afana nee-callouts zethu zakhiwe njengezixhobo zethu esizinikiweyo ezinesiseko kunye neeklasi zesilungisi.

<div class="callout">...</div>

KwiCSS yakho, unokuba nento efana nale ilandelayo apho isambuku sesitayile senziwe nge .callout. Emva koko, izimbo ezikhethekileyo phakathi kweyantlukwano nganye ilawulwa ngodidi lwesilungisi.

// Base class
.callout {}

// Modifier classes
.callout-info {}
.callout-warning {}
.callout-danger {}

Kwi-callouts, eso sitayile esisodwa siyinto nje border-left-color. Xa udibanisa iklasi yesiseko kunye nenye yezo klasi zokuguqula, ufumana usapho lwakho olupheleleyo:
