I-Flex
Ngokushesha phatha isakhiwo, ukuqondanisa, nosayizi wamakholomu egridi, ukuzulazula, izingxenye, nokunye okwengeziwe ngohlelo olugcwele lwezinsiza eziphendulayo ze-flexbox. Ukuze uthole ukuqaliswa okuyinkimbinkimbi, i-CSS yangokwezifiso ingase idingeke.
Nika amandla ukuziphatha okuguquguqukayo
Sebenzisa display
izinsiza ukuze udale isiqukathi se-flexbox futhi uguqule izici zezingane eziqondile zibe izinto eziguqukayo. Iziqukathi ze-Flex nezinto ziyakwazi ukuguqulwa ngokuqhubekayo ngezakhiwo ezengeziwe eziguqukayo.
<div class="d-flex p-2 bd-highlight">I'm a flexbox container!</div>
<div class="d-inline-flex p-2 bd-highlight">I'm an inline flexbox container!</div>
Ukwehluka okusabelayo kukhona .d-flex

Isiqondiso
Setha isiqondiso sezinto eziguqukayo esitsheni esiguquguqukayo esinezinsiza zokuqondisa. Ezimweni eziningi ungashiya isigaba esivundlile lapha njengoba okuzenzakalelayo kwesiphequluli kuyi- row
. Nokho, ungase uhlangabezane nezimo lapho ubudinga ukusetha ngokusobala leli nani (njengezakhiwo eziphendulayo).
Sebenzisa .flex-row
ukusetha isiqondiso esivundlile (okuzenzakalelayo kwesiphequluli), noma .flex-row-reverse
ukuqala indawo evundlile ukusuka kolunye uhlangothi.
<div class="d-flex flex-row bd-highlight mb-3">

<div class="p-2 bd-highlight">Flex item 2</div>
<div class="p-2 bd-highlight">Flex item 3</div>
</div>
Sebenzisa .flex-column
ukusetha isiqondiso esiqondile, noma .flex-column-reverse
ukuqala isiqondiso esiqondile ukusuka kolunye uhlangothi.
<div class="d-flex flex-column bd-highlight mb-3">
<div class="p-2 bd-highlight">Flex item 1</div>
<div class="p-2 bd-highlight">Flex item 2</div>

Qondanisa izinto
Sebenzisa align-items
izinsiza ezitsheni ze-flexbox ukuze uguqule ukuqondanisa kwezinto eziguqukayo ku-axis enqamulayo (i-eksisi ka-y ezoqala, i-x-eksisi uma flex-direction: column
). Khetha kokuthi start
, end

Sebenzisa align-self
izinsiza ezintweni ze-flexbox ukuze uguqule ngakunye ukuqondana kwazo ku-axis enqamulayo (i-eksisi ka-y ezoqala, i-x-eksisi uma flex-direction: column
). Khetha ezinkethweni ezifanayo njengokuthi align-items
: start

Gcwalisa
Sebenzisa .flex-fill
ikilasi ochungechungeni lwezici zezelamani ukuze uziphoqelele ebubanzini obulingana nokuqukethwe kwazo (noma ububanzi obulinganayo uma okuqukethwe kwazo kungadluli amabhokisi azo emngceleni) kuyilapho uthatha yonke indawo evundlile etholakalayo.
<div class="d-flex bd-highlight">

Khula ushwabane
Sebenzisa .flex-grow-*
izinsiza ukuze uguqule ikhono lento eguquguqukayo ukuze ikhule ukuze ugcwalise isikhala esitholakalayo. Esibonelweni esingezansi, .flex-grow-1
izakhi zisebenzisa sonke isikhala esitholakalayo, kuyilapho zivumela izinto ezimbili ezisele eziguquguqukayo zibe indawo yazo edingekayo.
<div class="d-flex bd-highlight">

Sebenzisa .flex-shrink-*
izinsiza ukuze uguqule ikhono lento eguquguqukayo ukuze inciphe uma kudingeka. Esibonelweni esingezansi, into yesibili eguquguqukayo nayo .flex-shrink-1
iphoqeleka ukuthi isonge okuqukethwe kwayo emugqeni omusha, "ukuncipha" ukuze kuvunyelwe isikhala esengeziwe sento eguquguqukayo yangaphambilini nge- .w-100
.
<div class="d-flex bd-highlight">

Amamajini azenzakalelayo
I-Flexbox ingenza izinto ezinhle kakhulu uma uhlanganisa ukuqondanisa okuguquguqukayo namamajini azenzakalelayo. Okuboniswe ngezansi izibonelo ezintathu zokulawula izinto eziguqukayo usebenzisa amamajini azenzakalelayo: okuzenzakalelayo (ayikho imajini ezenzakalelayo), ukusunduza izinto ezimbili kwesokudla ( .me-auto
), nokusunduza izinto ezimbili kwesokunxele ( .ms-auto
).

Shintsha ukuhleleka okubonakalayo kwezinto ezithile eziguquguqukayo ngezinsiza ezimbalwa order
. Sinikeza kuphela izinketho zokwenza into kuqala noma yokugcina, kanye nokusetha kabusha ukuze usebenzise i-oda le-DOM. Njengoba order
kuthatha noma yiliphi inani eliphelele ukusuka ku-0 kuye ku-5, engeza i-CSS yangokwezifiso kunoma imaphi amanani engeziwe adingekayo.
