Isikhala

I-Bootstrap ihlanganisa ububanzi bemajini esabelayo e-shorthand, i-padding, namakilasi ensiza ye-gap ukuze kulungiswe ukubukeka kwento.

Kuleli khasi

I-Margin kanye ne-padding

Nikeza okusabelayo okunobungane marginnoma paddingamanani kusici noma isethi engaphansi yezinhlangothi zayo ezinezigaba ezimfishane. Kufaka phakathi ukusekelwa kwezakhiwo ezingazodwana, zonke izakhiwo, kanye nezakhiwo eziqondile nezivundlile. Amakilasi akhiwe kusuka kumephu ye-Sass ezenzakalelayo ukusuka .25remku- 3rem.

Isaziso

Izinsiza zokuhlukanisa ezisebenza kuwo wonke ama-breakpoint, ukusuka xskuye ukuya ku- xxl, azinaso isifinyezo se-breakpoint kuzo. Lokhu kungenxa yokuthi lawo makilasi asetshenziswa ukusuka min-width: 0naphezulu, futhi ngaleyo ndlela awaboshiwe umbuzo wemidiya. Ama-breakpoint asele, nokho, afaka isifinyezo se-breakpoint.

Amakilasi aqanjwe kusetshenziswa ifomethi {property}{sides}-{size}yokuthi xs, , , , kanye .{property}{sides}-{breakpoint}-{size}smmdlgxlxxl

Lapho impahla ingenye ye:

m- amakilasi asethiwemargin
p- amakilasi asethiwepadding

Lapho izinhlangothi zingenye yalezi:

t- amakilasi abeka margin-topnomapadding-top
b- amakilasi abeka margin-bottomnomapadding-bottom
s- (qala) amakilasi asethayo margin-leftnoma padding-leftku-LTR, margin-rightnoma padding-rightku-RTL
e- (ekugcineni) kumakilasi asethayo margin-rightnoma padding-rightku-LTR, margin-leftnoma padding-leftku-RTL
x- amakilasi asetha kokubili *-leftfuthi*-right
y- amakilasi asetha kokubili *-topfuthi*-bottom
blank - amakilasi asetha i-a marginnoma paddingkuzo zonke izinhlangothi ezi-4 zesici

Lapho usayizi ungomunye walokhu:

0- amakilasi asusa marginnoma paddingngokuyibeka kuwo0
1- (ngokuzenzakalelayo) kumakilasi asetha i- marginnoma paddingku$spacer * .25
2- (ngokuzenzakalelayo) kumakilasi asetha i- marginnoma paddingku$spacer * .5
3- (ngokuzenzakalelayo) kumakilasi asetha i- marginnoma paddingku$spacer
4- (ngokuzenzakalelayo) kumakilasi asetha i- marginnoma paddingku$spacer * 1.5
5- (ngokuzenzakalelayo) kumakilasi asetha i- marginnoma paddingku$spacer * 3
auto- kumakilasi asetha okuthi marginokuzenzakalelayo

(Ungangeza osayizi abengeziwe ngokungeza okufakiwe $spacerskokuhluka kwemephu ye-Sass.)

Izibonelo

Nazi ezinye izibonelo ezimele lawa makilasi:

.mt-0 {
  margin-top: 0 !important;
}

.ms-1 {
  margin-left: ($spacer * .25) !important;
}

.px-2 {
  padding-left: ($spacer * .5) !important;
  padding-right: ($spacer * .5) !important;
}

.p-3 {
  padding: $spacer !important;
}

I-Horizontal centering

Ukwengeza, i-Bootstrap iphinde ihlanganise .mx-autonekilasi lokumisa phakathi nendawo okuqukethwe kwezinga lebhulokhi enobubanzi obungashintshi—okungukuthi, okuqukethwe okunayo display: blockkanye widthnesethi—ngokusetha amamajini avundlile ukuze auto.

Isici esimaphakathi

<div class="mx-auto" style="width: 200px;">
  Centered element
</div>

Imajini enegethivu

Ku-CSS, marginizakhiwo zingasebenzisa amanani angalungile ( paddingangeke). Lawa mamajini anegethivu akhutshazwa ngokuzenzakalela , kodwa anganikwa amandla ku-Sass ngokusetha $enable-negative-margins: true.

I-syntax icishe ifane nokuzenzakalelayo, izinsiza zemajini ephozithivu, kodwa ngokwengezwa nkwangaphambi kosayizi oceliwe. Nasi ikilasi lesibonelo eliphambene ne- .mt-1:

.mt-n1 {
  margin-top: -0.25rem !important;
}

Igebe

Uma usebenzisa i- display: grid, ungasebenzisa gapizinsiza esiqukathi segridi engumzali. Lokhu kungasindisa ekungezeni izinsiza zemajini ezintweni zegridi ngayinye (izingane display: gridzesiqukathi). Izinsiza ze-Gap zisabela ngokuzenzakalelayo, futhi zenziwa ngezinsiza zethu ze-API, ngokusekelwe $spacerskumephu ye-Sass.

Into yegridi 1

Into yegridi 2

Into yegridi 3

<div class="d-grid gap-3">
  <div class="p-2 bg-light border">Grid item 1</div>
  <div class="p-2 bg-light border">Grid item 2</div>
  <div class="p-2 bg-light border">Grid item 3</div>
</div>

Ukusekelwa kufaka phakathi izinketho zokusabela kuzo zonke izindawo zokunqamuka kwegridi ye-Bootstrap, kanye nosayizi abayisithupha abavela $spacerskumephu ( 0– 5). Asikho .gap-autoisigaba sosizo njengoba sifana ngokuphumelelayo ne- .gap-0.

Sass

Amamephu

Izinsiza zokubeka isikhala zimenyezelwa ngemephu ye-Sass bese zenziwa ngezinsiza zethu ze-API.

$spacer: 1rem;
$spacers: (
  0: 0,
  1: $spacer * .25,
  2: $spacer * .5,
  3: $spacer,
  4: $spacer * 1.5,
  5: $spacer * 3,
);

$negative-spacers: if($enable-negative-margins, negativify-map($spacers), null);

Izinsiza zokubeka isikhala zimenyezelwa kuzinsiza zethu ze-API ku- scss/_utilities.scss. Funda indlela yokusebenzisa i-API yezinsiza.
