I-Utility API

I-Utility API iyithuluzi elisekelwe kwa-Sass lokukhiqiza amakilasi osizo.

Kuleli khasi

Izinsiza ze-Bootstrap zenziwa nge-API yethu yokusetshenziswa futhi zingasetshenziselwa ukuguqula noma ukunweba isethi yethu ezenzakalelayo yamakilasi okusetshenziswayo nge-Sass. I-API yethu yokusetshenziswa isekelwe ochungechungeni lwamamephu we-Sass nemisebenzi yokukhiqiza imindeni yamakilasi ngezinketho ezihlukahlukene. Uma ungawazi amamephu akwa-Sass, funda kumadokhumenti e- Sass asemthethweni ukuze uqalise.

Imephu $utilitiesiqukethe zonke izinsiza zethu futhi kamuva ihlanganiswa $utilitiesnemephu yakho yangokwezifiso, uma ikhona. Imephu yokusetshenziswa iqukethe uhlu olunokhiye lwamaqembu asetshenziswayo amukela izinketho ezilandelayo:

Inketho	Uhlobo	Incazelo
`property`	Kudingeka	Igama lesakhiwo, lokhu kungaba iyunithi yezinhlamvu noma uchungechunge lwezintambo (isb., amaphedi avundlile noma amamajini).
`values`	Kudingeka	Uhlu lwamanani, noma imephu uma ungafuni ukuthi igama lekilasi lifane nevelu. Uma `null`isetshenziswa njengokhiye wemephu, ayihlanganiswa.
`class`	Ongakukhetha	Okuguquguqukayo kwegama lekilasi uma ungafuni ukuthi lifane nesakhiwo. Uma kwenzeka unganikezi `class`ukhiye futhi `property`ukhiye kuwuchungechunge lwezintambo, igama lekilasi lizoba into yokuqala yamalungu `property`afanayo.
`state`	Ongakukhetha	Uhlu lwezinhlobonhlobo zesigaba-mbumbulu ezifana `:hover`noma `:focus`ezizokhiqizwa insiza. Alikho inani elizenzakalelayo.
`responsive`	Ongakukhetha	I-Boolean ekhombisa uma amakilasi asabelayo adinga ukwenziwa. `false`ngephutha.
`rfs`	Ongakukhetha	I-boolean ukuze unike amandla ukuncishiswa koketshezi. Bheka ikhasi le- RFS ukuze uthole ukuthi lokhu kusebenza kanjani. `false`ngephutha.
`print`	Ongakukhetha	I-Boolean ekhombisa uma amakilasi okuphrinta adinga ukwenziwa. `false`ngephutha.
`rtl`	Ongakukhetha	I-Boolean ekhombisa ukuthi ukusetshenziswa kufanele kugcinwe ku-RTL. `true`ngephutha.

I-API yachaza

Zonke izinto eziguquguqukayo zengezwa $utilitieskokuguquguqukayo ngaphakathi kweshidi lethu _utilities.scsslesitayela. Iqembu ngalinye lezinsiza libukeka kanje:

$utilities: (
  "opacity": (
    property: opacity,
    values: (
      0: 0,
      25: .25,
      50: .5,
      75: .75,
      100: 1,
    )
  )
 );

Okukhipha okulandelayo:

.opacity-0 { opacity: 0; }
.opacity-25 { opacity: .25; }
.opacity-50 { opacity: .5; }
.opacity-75 { opacity: .75; }
.opacity-100 { opacity: 1; }

Isiqalo sekilasi langokwezifiso

Sebenzisa classinketho ukuze uguqule isiqalo sekilasi esisetshenziswe ku-CSS ehlanganisiwe:

$utilities: (
  "opacity": (
    property: opacity,
    class: o,
    values: (
      0: 0,
      25: .25,
      50: .5,
      75: .75,
      100: 1,
    )
  )
 );

Okukhiphayo:

.o-0 { opacity: 0; }
.o-25 { opacity: .25; }
.o-50 { opacity: .5; }
.o-75 { opacity: .75; }
.o-100 { opacity: 1; }

Amazwe

Sebenzisa stateinketho ukuze ukhiqize ukuhluka kwesigaba-mbumbulu. Izibonelo zamakilasi mbumbulu yilezi :hoverkanye :focus. Uma uhlu lwezifunda lunikezwa, amagama ekilasi adalelwa leso sigaba-mbumbulu. Isibonelo, ukuze uguqule ukukhanya ku-hambisa phezulu, engeza state: hoverfuthi uzongena .opacity-hover:hoverku-CSS yakho ehlanganisiwe.

Udinga amakilasi-mbumbulu amaningi? Sebenzisa uhlu lwezifundazwe oluhlukaniswe isikhala: state: hover focus.

$utilities: (
  "opacity": (
    property: opacity,
    class: opacity,
    state: hover,
    values: (
      0: 0,
      25: .25,
      50: .5,
      75: .75,
      100: 1,
    )
  )
);

Okukhiphayo:

.opacity-0-hover:hover { opacity: 0 !important; }
.opacity-25-hover:hover { opacity: .25 !important; }
.opacity-50-hover:hover { opacity: .5 !important; }
.opacity-75-hover:hover { opacity: .75 !important; }
.opacity-100-hover:hover { opacity: 1 !important; }

Izinsiza ezisabelayo

Engeza i- responsiveboolean ukuze ukhiqize izinsiza ezisabelayo (isb, .opacity-md-25) kuwo wonke ama-breakpoint .

$utilities: (
  "opacity": (
    property: opacity,
    responsive: true,
    values: (
      0: 0,
      25: .25,
      50: .5,
      75: .75,
      100: 1,
    )
  )
 );

Okukhiphayo:

.opacity-0 { opacity: 0 !important; }
.opacity-25 { opacity: .25 !important; }
.opacity-50 { opacity: .5 !important; }
.opacity-75 { opacity: .75 !important; }
.opacity-100 { opacity: 1 !important; }

@media (min-width: 576px) {
  .opacity-sm-0 { opacity: 0 !important; }
  .opacity-sm-25 { opacity: .25 !important; }
  .opacity-sm-50 { opacity: .5 !important; }
  .opacity-sm-75 { opacity: .75 !important; }
  .opacity-sm-100 { opacity: 1 !important; }
}

@media (min-width: 768px) {
  .opacity-md-0 { opacity: 0 !important; }
  .opacity-md-25 { opacity: .25 !important; }
  .opacity-md-50 { opacity: .5 !important; }
  .opacity-md-75 { opacity: .75 !important; }
  .opacity-md-100 { opacity: 1 !important; }
}

@media (min-width: 992px) {
  .opacity-lg-0 { opacity: 0 !important; }
  .opacity-lg-25 { opacity: .25 !important; }
  .opacity-lg-50 { opacity: .5 !important; }
  .opacity-lg-75 { opacity: .75 !important; }
  .opacity-lg-100 { opacity: 1 !important; }
}

@media (min-width: 1200px) {
  .opacity-xl-0 { opacity: 0 !important; }
  .opacity-xl-25 { opacity: .25 !important; }
  .opacity-xl-50 { opacity: .5 !important; }
  .opacity-xl-75 { opacity: .75 !important; }
  .opacity-xl-100 { opacity: 1 !important; }
}

@media (min-width: 1400px) {
  .opacity-xxl-0 { opacity: 0 !important; }
  .opacity-xxl-25 { opacity: .25 !important; }
  .opacity-xxl-50 { opacity: .5 !important; }
  .opacity-xxl-75 { opacity: .75 !important; }
  .opacity-xxl-100 { opacity: 1 !important; }
}

Ukushintsha izinsiza

Khipha izinsiza ezikhona ngokusebenzisa ukhiye ofanayo. Isibonelo, uma ufuna amakilasi ezinsiza ezengeziwe eziphendulayo, ungenza lokhu:

$utilities: (
  "overflow": (
    responsive: true,
    property: overflow,
    values: visible hidden scroll auto,
  ),
);

Phrinta izinsiza

Ukunika amandla printinketho kuzophinda kukhiqize amakilasi ezinsiza zokuphrinta, asetshenziswa kuphela ngaphakathi @media print { ... }kombuzo wemidiya.

$utilities: (
  "opacity": (
    property: opacity,
    print: true,
    values: (
      0: 0,
      25: .25,
      50: .5,
      75: .75,
      100: 1,
    )
  )
 );

Okukhiphayo:

.opacity-0 { opacity: 0 !important; }
.opacity-25 { opacity: .25 !important; }
.opacity-50 { opacity: .5 !important; }
.opacity-75 { opacity: .75 !important; }
.opacity-100 { opacity: 1 !important; }

@media print {
  .opacity-print-0 { opacity: 0 !important; }
  .opacity-print-25 { opacity: .25 !important; }
  .opacity-print-50 { opacity: .5 !important; }
  .opacity-print-75 { opacity: .75 !important; }
  .opacity-print-100 { opacity: 1 !important; }
}

Ukubaluleka

Zonke izinsiza ezikhiqizwe i-API zifaka phakathi !importantukuqinisekisa ukuthi zibhala ngaphezulu izingxenye namakilasi okulungisa njengoba kuhlosiwe. Ungakwazi ukuguqula lesi silungiselelo emhlabeni jikelele ngokushintshashintsha $enable-important-utilities(okuzenzakalelayo kuye kokuthi true).

Ukusebenzisa i-API

Manje njengoba usuyazi ukuthi i-API yezinsiza isebenza kanjani, funda ukuthi ungangeza kanjani amakilasi akho angokwezifiso futhi ulungise izinsiza zethu ezizenzakalelayo.

Engeza izinsiza

Izinsiza ezintsha zingangezwa $utilitieskumephu ezenzakalelayo nge- map-merge. Qiniseka ukuthi amafayela ethu adingekayo akwa-Sass futhi _utilities.scssangeniswa kuqala, bese usebenzisa map-mergeukungeza izinsiza zakho ezengeziwe. Isibonelo, nansi indlela yokwengeza cursorinsiza ephendulayo enamanani amathathu.

@import "bootstrap/scss/functions";
@import "bootstrap/scss/variables";
@import "bootstrap/scss/utilities";

$utilities: map-merge(
  $utilities,
  (
    "cursor": (
      property: cursor,
      class: cursor,
      responsive: true,
      values: auto pointer grab,
    )
  )
);

Shintsha izinsiza

Lungisa izinsiza ezikhona $utilitieskumephu ezenzakalelayo map-getkanye map-mergenemisebenzi. Esibonelweni esingezansi, sengeza inani elingeziwe widthkuzinsiza. Qala nge-initial map-mergebese usho ukuthi iyiphi insiza ofuna ukuyishintsha. Kusuka lapho, landa "width"imephu ebekwe esidlekeni map-getukuze ufinyelele futhi ulungise izinketho namanani ensiza.

@import "bootstrap/scss/functions";
@import "bootstrap/scss/variables";
@import "bootstrap/scss/utilities";

$utilities: map-merge(
  $utilities,
  (
    "width": map-merge(
      map-get($utilities, "width"),
      (
        values: map-merge(
          map-get(map-get($utilities, "width"), "values"),
          (10: 10%),
        ),
      ),
    ),
  )
);

Nika amandla ukuphendula

Unganika amandla amakilasi asabelayo kusethi ekhona yezinsiza okwamanje ezingasabeli ngokuzenzakalela. Isibonelo, ukwenza borderamakilasi aphendule:

@import "bootstrap/scss/functions";
@import "bootstrap/scss/variables";
@import "bootstrap/scss/utilities";

$utilities: map-merge(
  $utilities, (
    "border": map-merge(
      map-get($utilities, "border"),
      ( responsive: true ),
    ),
  )
);

Lokhu manje kuzodala ukuhlukahluka okusabelayo kwephuzu .borderngalinye .border-0lokuhlukana. I-CSS yakho ekhiqiziwe izobukeka kanje:

.border { ... }
.border-0 { ... }

@media (min-width: 576px) {
  .border-sm { ... }
  .border-sm-0 { ... }
}

@media (min-width: 768px) {
  .border-md { ... }
  .border-md-0 { ... }
}

@media (min-width: 992px) {
  .border-lg { ... }
  .border-lg-0 { ... }
}

@media (min-width: 1200px) {
  .border-xl { ... }
  .border-xl-0 { ... }
}

@media (min-width: 1400px) {
  .border-xxl { ... }
  .border-xxl-0 { ... }
}

Qamba kabusha izinsiza

Izinsiza ze-v4 ezingekho, noma ezijwayele ukuqamba amagama? Izinsiza ze-API zingasetshenziselwa ukubhala ngaphezulu umphumela classwokusetshenziswa okunikeziwe—ngokwesibonelo, ukuqamba kabusha .ms-*izinsiza ziye ku-oldish .ml-*:

@import "bootstrap/scss/functions";
@import "bootstrap/scss/variables";
@import "bootstrap/scss/utilities";

$utilities: map-merge(
  $utilities, (
    "margin-start": map-merge(
      map-get($utilities, "margin-start"),
      ( class: ml ),
    ),
  )
);

Susa izinsiza

Susa noma yiziphi izinsiza ezizenzakalelayo ngokusetha ukhiye weqembu ku- null. Isibonelo, ukususa zonke widthizinsiza zethu, dala $utilities map-mergefuthi wengeze "width": nullngaphakathi.

@import "bootstrap/scss/functions";
@import "bootstrap/scss/variables";
@import "bootstrap/scss/utilities";

$utilities: map-merge(
  $utilities,
  (
    "width": null
  )
);

Susa isisetshenziswa ku-RTL

Amanye amakesi onqenqema enza isitayela se-RTL sibe nzima , njengokunqamuka kwemigqa ngesi-Arabhu. Ngakho izinsiza zingehliswa ekuphumeni kwe-RTL ngokusetha rtlinketho kokuthi false:

$utilities: (
  "word-wrap": (
    property: word-wrap word-break,
    class: text,
    values: (break: break-word),
    rtl: false
  ),
);

Okukhiphayo:

/* rtl:begin:remove */
.text-break {
  word-wrap: break-word !important;
  word-break: break-word !important;
}
/* rtl:end:remove */

Lokhu akukhiphi lutho ku-RTL, ngenxa yomyalelo wokulawula we-RTLCSSremove .
