Flex
Lawula ngokukhawuleza uyilo, ulungelelwaniso, kunye nobungakanani bekholamu zegridi, ukukhangela, izinto, kunye nokunye okuninzi ngesuti epheleleyo yezixhobo eziphendulayo zebhokisi eguqukayo. Ukuphunyezwa okuntsonkothileyo ngakumbi, i-CSS yesiko ingafuneka.
Nika amandla ukuziphatha okuguquguqukayo
Faka displayizinto eziluncedo ukwenza isikhongozeli se-flexbox kwaye uguqule izinto ezithe ngqo zabantwana zibe zizinto eziguqukayo. Izikhongozeli zeFlex kunye nezinto ziyakwazi ukuguqulwa ngakumbi ngeempawu ezongezelelweyo ze-flex.
<div class="d-flex p-2">I'm a flexbox container!</div><div class="d-inline-flex p-2">I'm an inline flexbox container!</div>Iiyantlukwano eziphendulayo zikwakhona .d-flexkwaye .d-inline-flex.

Isalathiso
Seta icala lezinto eziguquguqukayo kwisikhongozeli esine-flex esineendlela eziluncedo. Kwiimeko ezininzi ungashiya udidi oluthe tye apha njengoko umkhangeli zincwadi ongagqibekanga unjalo row. Nangona kunjalo, unokuhlangabezana neemeko apho ubufuna ukuseta ngokuthe gca eli xabiso (njengoyilo oluphendulayo).
Sebenzisa .flex-rowukuseta isalathiso esithe tye (isikhangeli esingagqibekanga), okanye .flex-row-reverseukuqalisa ulwalathiso oluthe tye ukusuka kwelinye icala.
<div class="d-flex flex-row mb-3">
<div class="p-2">Flex item 1</div>
<div class="p-2">Flex item 2</div>
<div class="p-2">Flex item 3</div>
</div>

<div class="p-2">Flex item 1</div>
<div class="p-2">Flex item 2</div>
<div class="p-2">Flex item 3</div>
</div>Sebenzisa .flex-columnukuseta icala elithe nkqo, okanye .flex-column-reverseukuqalisa icala elithe nkqo ukusuka kwelinye icala.
<div class="d-flex flex-column mb-3">
<div class="p-2">Flex item 1</div>

Lungelelanisa izinto
Sebenzisa align-itemsizinto eziluncedo kwizikhongozeli zeflexbox ukutshintsha ulungelelwaniso lwezinto eziguqukayo kwi-axis enqamlezileyo (umgca ongu-y ukuqalisa, u-x-axis ukuba flex-direction: column). Khetha kwi start, end, center, baseline, okanye stretch(ukungagqibeki kwesikhangeli).
<div class="d-flex align-items-start">...</div>

Khula kwaye ucuthe
Sebenzisa .flex-grow-*izinto eziluncedo ukuguqula ukukwazi kwento eguqukayo ukukhula ukuzalisa indawo ekhoyo. Kulo mzekelo ungezantsi, .flex-grow-1izinto zisebenzisa yonke indawo ekhoyo, ngelixa uvumela izinto ezimbini eziseleyo zibe yindawo yazo eyimfuneko.
<div class="d-flex">
<div class="p-2 flex-grow-1">Flex item</div>
<div class="p-2">Flex item</div>
<div class="p-2">Third flex item</div>
</div>Sebenzisa .flex-shrink-*izinto eziluncedo ukuguqula isakhono sento eguqukayo ukuba icuthe ukuba kuyimfuneko. Kulo mzekelo ungezantsi, into yesibini eguquguqukayo kunye .flex-shrink-1nokunyanzeliswa ukuba idibanise imixholo yayo kumgca omtsha, "ukunciphisa" ukuvumela indawo engaphezulu yento yangaphambili ye-flex .w-100.

Imida ezenzekelayo
I-Flexbox inokwenza izinto ezintle kakhulu xa udibanisa ulungelelwaniso oluguquguqukayo kunye nemida yeauto. Iboniswe ngezantsi yimizekelo emithathu yokulawula izinto eziguqukayo kusetyenziswa imida ye-auto: okungagqibekanga (akukho mda we-auto), ukutyhala izinto ezimbini ngasekunene ( .me-auto), nokutyhala izinto ezimbini ekhohlo ( .ms-auto).

Sinikezela kuphela iinketho zokwenza into yokuqala okanye yokugqibela, kunye nokusetha kwakhona ukusebenzisa iodolo yeDOM. Njengoko orderkuthatha naliphi na inani elipheleleyo ukusuka ku-0 ukuya ku-5, yongeza i-CSS yesiko kuwo nawaphi na amaxabiso afunekayo.
<div class="d-flex flex-nowrap">
