Mulimu okuwagira eby’obugagga ssekinnoomu, eby’obugagga byonna, n’eby’obugagga ebyesimbye n’eby’okwesimbye. Ebika bizimbibwa okuva ku maapu ya Sass eya bulijjo okuva ku .25remokutuuka ku 3rem.

Okuwandiika ebigambo

Kino kiri bwe kityo kubanga kiraasi ezo zikozesebwa okuva min-width: 0n’okudda waggulu, era bwe zityo tezisibibwa ku kubuuza kwa mikutu. Ebifo ebisigaddewo, naye, bibaamu enfunyiro y’okumenya.

Ebisulo bituumibwa amannya nga tukozesa ensengeka {property}{sides}-{size}ya xs, , , ne .{property}{sides}-{breakpoint}-{size}smmdlgxl

Eby’okulabirako

Wano waliwo ebyokulabirako ebikiikirira ebika bino:

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

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

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

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

Okuteeka wakati mu bbanga (horizontal centering).

Okugatta ku ekyo, Bootstrap era erimu .mx-autokiraasi ey’okussa wakati mu bbanga (horizontal centering fixed-width block level content) ebirimu —kwe kugamba, ebirimu ebirina display: blockn’ekisengekeddwa width—nga oteeka emimwa egy’okwebungulula ku auto.

Ekintu ekiri wakati

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

Negative margin

Mu CSS, margineby'obugagga bisobola okukozesa emiwendo emibi ( paddingtesobola). Okuva ku 4.2, twongeddeko ebikozesebwa eby’omugatte omubi ku buli sayizi ya namba enzijuvu etali ya ziro ewandiikiddwa waggulu (okugeza, 1, 2, 3, 4, 5). Ebikozesebwa bino birungi nnyo mu kulongoosa emidumu gy’empagi za grid okuyita mu bifo ebimenya.

Ensengeka y'ebigambo kumpi y'emu n'ebikozesebwa ebisookerwako, ebirungi margin utilities, naye nga kwogasse nnga tebannaba sayizi esabiddwa. Wano waliwo ekibiina eky'okulabirako ekikontana ne .mt-1:

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

Wano waliwo ekyokulabirako ky'okulongoosa ekisenge kya Bootstrap ku kifo mdeky'okumenya eky'omu makkati ( ) n'okudda waggulu. Twongedde ku .colpadding ne .px-md-5ate oluvannyuma ne tuziyiza ekyo ne .mx-md-n5ku muzadde .row.

Okupakinga empagi eza custom

<div class="row mx-md-n5">
  <div class="col px-md-5"><div class="p-3 border bg-light">Custom column padding</div></div>
  <div class="col px-md-5"><div class="p-3 border bg-light">Custom column padding</div></div>
