  margin-top: 0 !important;
}

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

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

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

Whakawaenga waenganui

I tua atu, kei roto ano i a Bootstrap tetahi .mx-autokaraehe mo te whakamau whakapae i nga ihirangi taumata paraka-whanui-a-raa, he ihirangi kei roto display: blockme te widthhuinga—ma te tautuhi i nga tawhē whakapae ki auto.

Huānga Pokapū

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

Tawhē tōraro

I roto i te CSS, marginka taea e nga taonga te whakamahi i nga uara kino ( paddingkaore e taea). Ko enei tawhē kino kua monoa ma te taunoa , engari ka taea te whakahohe ki Sass ma te tautuhi $enable-negative-margins: true.

He rite tonu te wetereo ki te taunoa, nga taputapu tawhē pai, engari me te taapiri i nmua i te rahi i tonoa. Anei tetahi tauira akomanga he rerekee o .mt-1:

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

āputa

Ina whakamahi display: gridkoe, ka taea e koe te whakamahi i nga gaptaputapu kei runga i te ipu matiti matua. Ka taea e tenei te tiaki i te taapiri i nga taputapu tawhē ki nga mea matiti takitahi (tamariki o te display: gridipu). Ko nga taputapu a Gap he whakautu taunoa, ka hangaia ma o maatau taputapu API, i runga i te $spacersmahere Sass.

Sass

Mahere

Ka whakahuahia nga taputapu mokowhiti ma te mahere Sass katahi ka hangaia me o maatau taputapu 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);

API taputapu
