Izithuba

I-Bootstrap ibandakanya uluhlu olubanzi lomda ophendulayo omfutshane, i-padding, kunye neeklasi eziluncedo ze-gap ukulungisa inkangeleko yento.

Kweli phepha

Umda kunye ne-padding

Yabela i-responsive-friendly marginor paddingvalues to element or subset of its sides neeclasses shorthand. Ibandakanya inkxaso yeepropati zomntu ngamnye, zonke iipropati, kunye neepropati ezithe nkqo nezithe tye. Iiklasi zakhiwe ukusuka kwimephu ye-Sass engagqibekanga ukusuka .25remkwi 3rem.

Ukuphawula

Izithuba zemisebenzi ezisebenza kuzo zonke iindawo zokuqhawula, ukusuka xsukuya ukuya xxl, azinazifinyezo zebreakpoint kuzo. Oku kungenxa yokuba ezo klasi zisetyenziswa ukusuka min-width: 0nangaphezulu, kwaye ke azibotshwanga ngumbuzo wemidiya. Ii-breakpoints ezishiyekileyo, nangona kunjalo, zibandakanya isifinyezo se-breakpoint.

Iiklasi zithiywe kusetyenziswa ifomathi {property}{sides}-{size}ye xskunye {property}{sides}-{breakpoint}-{size}ne sm, md, lg, xl, kunye xxl.

Apho ipropati yenye ye:

m- kwiiklasi ezibekamargin
p- kwiiklasi ezibekapadding

Apho amacala yenye ye:

t- kwiiklasi ezibeka margin-topokanyepadding-top
b- kwiiklasi ezibeka margin-bottomokanyepadding-bottom
s- (qala) kwiiklasi ezisetayo margin-leftokanye padding-leftkwi-LTR, margin-rightokanye padding-rightkwi-RTL
e- (isiphelo) kwiiklasi ezisetayo margin-rightokanye padding-rightkwi-LTR, margin-leftokanye padding-leftkwi-RTL
x- kwiiklasi ezibeka zombini *-leftkunye*-right
y- kwiiklasi ezibeka zombini *-topkunye*-bottom
blank - kwiiklasi ezicwangcisa i marginokanye paddingkuwo onke amacala ama-4 ento

Apho ubukhulu buyenye ye:

0- kwiiklasi ezisusa marginokanye paddingngokuyicwangcisa0
1- (ngokungagqibekanga) kwiiklasi ezicwangcisa i marginokanye paddingukuya$spacer * .25
2- (ngokungagqibekanga) kwiiklasi ezicwangcisa i marginokanye paddingukuya$spacer * .5
3- (ngokungagqibekanga) kwiiklasi ezicwangcisa i marginokanye paddingukuya$spacer
4- (ngokungagqibekanga) kwiiklasi ezicwangcisa i marginokanye paddingukuya$spacer * 1.5
5- (ngokungagqibekanga) kwiiklasi ezicwangcisa i marginokanye paddingukuya$spacer * 3
auto- kwiiklasi eziseta i- marginauto

(Unokongeza ubungakanani obungakumbi ngokongeza amangeno $spacerskuguquko lwemephu ye-Sass.)

Imizekelo

Nantsi eminye imizekelo emele ezi klasi:

.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;
}

Ukuzinzisa okuthe tye

Ukongezelela, i-Bootstrap ikwabandakanya .mx-autoiklasi yokumisa i-horizontally centering blocked-width wide-fixed content level-oko kukuthi, umxholo onawo display: blockkunye widthnesethi-ngokubeka imida ethe tye ukuya auto.

Isiqalelo esisembindini

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

Umda ongalunganga

Kwi-CSS, marginiipropathi zinokusebenzisa amaxabiso angalunganga ( paddingawanako). Le mida ingalunganga ivaliwe ngokungagqibekanga , kodwa inokwenziwa kwi Sass ngokucwangcisa $enable-negative-margins: true.

I-syntax iphantse yafana nokungagqibekanga, izinto eziluncedo zomda, kodwa ngokongezwa nkwangaphambi kobungakanani obuceliweyo. Nanku umzekelo weklasi ochaseneyo .mt-1:

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

Umsantsa

Xa usebenzisa display: grid, unokusebenzisa gapizinto eziluncedo kwisikhongozeli segridi yomzali. Oku kunokonga ekongezeni izixhobo zomda kwizinto zegridi nganye (abantwana display: gridbesikhongozeli). I-Gap utility iphendula ngokungagqibekanga, kwaye iveliswa ngokusebenzisa izixhobo zethu ze-API, ngokusekelwe $spacerskwimephu ye-Sass.

Into yegridi 1

Into yegridi yesi-2

Into yegridi yesi-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>

Inkxaso ibandakanya iinketho zokuphendula kuzo zonke iindawo zokuqhawula igridi yeBootstrap, kunye nobukhulu obuthandathu ukusuka $spacerskwimephu ( 0– 5). Akukho .gap-autoklasi yoncedo njengoko iyafana ngokusebenzayo ne .gap-0.

Sass

Iimephu

Izithuba zemisebenzi zibhengezwa ngemephu ye-Sass kwaye ziveliswe ngezinto 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);
