Belgilash

xsBarcha to'xtash nuqtalari uchun qo'llaniladigan oraliq yordamchi dasturlarda xxlto'xtash nuqtasi qisqartmasi yo'q. Buning sababi shundaki, bu sinflar yuqoridan min-width: 0va yuqoridan qo'llaniladi va shuning uchun media so'rovi bilan bog'lanmaydi. Qolgan to'xtash nuqtalari esa to'xtash nuqtasi qisqartmasini o'z ichiga oladi.

Misollar

Mana bu sinflarning ba'zi namunaviy namunalari:

.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;
}

Gorizontal markazlashtirish

Bundan tashqari, Bootstrap shuningdek, gorizontal chegaralarni o'rnatish orqali .mx-autoqattiq kenglikdagi blok darajasidagi tarkibni, ya'ni mavjud tarkib display: blockva width​​to'plamni gorizontal markazlashtirish uchun sinfni o'z ichiga oladi auto.

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

Salbiy marja

CSS-da marginxususiyatlar salbiy qiymatlardan foydalanishi mumkin ( paddingmumkin). Ushbu salbiy chegaralar sukut bo'yicha o'chirilgan , lekin sozlash orqali Sass'da faollashtirilishi mumkin $enable-negative-margins: true.

Sintaksis sukut bo'yicha, ijobiy chegara yordam dasturlari bilan deyarli bir xil, ammo nso'ralgan o'lchamdan oldin qo'shilishi bilan. Bunga qarama-qarshi bo'lgan misol sinfi .mt-1:

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

dan foydalanayotganda display: grid, siz gapota-grid konteyneridagi yordamchi dasturlardan foydalanishingiz mumkin. display: gridBu alohida panjara elementlariga ( konteynerning bolalari) marja yordam dasturlarini qo'shish zaruriyatini tejash imkonini beradi . $spacersGap yordam dasturlari sukut bo'yicha javob beradi va Sass xaritasi asosida bizning API yordam dasturlarimiz orqali yaratiladi .

Qo'llab-quvvatlash barcha Bootstrap panjara to'xtash nuqtalari uchun javob beruvchi variantlarni, shuningdek, $spacersxaritadan oltita o'lchamni ( 0– 5) o'z ichiga oladi. Utility sinfi yo'q .gap-auto, chunki u samarali tarzda bir xil .gap-0.
