}

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

.px-2 {

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

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

Chopingasa pakati

Kuphatikiza apo, Bootstrap imaphatikizansopo .mx-autokalasi yokhazikika yopingasa mulingo wa block - ndiye kuti, zomwe zili display: blockndi widthseti - pokhazikitsa malire opingasa mpaka auto.

Chigawo chapakati

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

Mtsinje wopanda pake

Mu CSS, marginkatundu amatha kugwiritsa ntchito zinthu zolakwika ( paddingsangathe). Malire oyipa awa amazimitsidwa mwachisawawa , koma atha kuyatsa mu Sass pokhazikitsa$enable-negative-margins: true .

Mawuwo ali pafupifupi ofanana ndi osasinthika, abwino am'mphepete mwazinthu zofunikira, koma ndikuwonjezera nkukula kwake komwe kusanachitike. Nayi kalasi yachitsanzo yomwe ili yosiyana ndi .mt-1:

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

Kusiyana

Mukamagwiritsa ntchito display: grid, mutha kugwiritsa gapntchito zida zomwe zili pachidebe cha grid ya makolo. Izi zitha kupulumutsa pakuwonjezera zida zam'mphepete kuzinthu zamtundu uliwonse (ana a display: gridchidebe). Zida za Gap zimagwira ntchito mwachisawawa, ndipo zimapangidwa kudzera pazida zathu za API, kutengera $spacersmapu a Sass.

Grid chinthu 1

Grid chinthu 2

Grid chinthu 3

<div class="d-grid gap-3">
