I-Flex
Ngokushesha phatha ukwakheka, 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 displayizinsiza 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>Ukuhlukahluka okusabelayo kukhona .d-flexfuthi .d-inline-flex.
.d-flex.d-inline-flex.d-sm-flex.d-sm-inline-flex.d-md-flex.d-md-inline-flex.d-lg-flex.d-lg-inline-flex.d-xl-flex.d-xl-inline-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-rowukusetha isiqondiso esivundlile (okuzenzakalelayo kwesiphequluli), noma .flex-row-reverseukuqala indawo evundlile ukusuka kolunye uhlangothi.
<div class="d-flex flex-row bd-highlight mb-3">
<div class="p-2 bd-highlight">Flex item 1</div>
<div class="p-2 bd-highlight">Flex item 2</div>
<div class="p-2 bd-highlight">Flex item 3</div>
</div>
<div class="d-flex flex-row-reverse bd-highlight">
<div class="p-2 bd-highlight">Flex item 1</div>
<div class="p-2 bd-highlight">Flex item 2</div>
<div class="p-2 bd-highlight">Flex item 3</div>
</div>Sebenzisa .flex-columnukusetha isiqondiso esiqondile, noma .flex-column-reverseukuqala 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>

<div class="p-2 bd-highlight">Flex item 2</div>
<div class="p-2 bd-highlight">Flex item 3</div>
</div>Ukuhlukahluka okusabelayo kukhona futhi flex-direction.

Lungiselela okuqukethwe
Sebenzisa justify-contentizinsiza ezitsheni ze-flexbox ukuze uguqule ukuqondanisa kwezinto eziguqukayo ku-eksisi eyinhloko (i-eksisi engu-x ezoqala, i-eksisi engu-y uma flex-direction: column). Khetha kokuthi start(okuzenzakalelayo kwesiphequluli), end, center, between, noma around.
<div class="d-flex justify-content-start">...</div>
<div class="d-flex justify-content-end">...</div>
<div class="d-flex justify-content-center">...</div>
<div class="d-flex justify-content-between">...</div>
<div class="d-flex justify-content-around">...</div>Ukuhlukahluka okusabelayo kukhona futhi justify-content.

Qondanisa izinto
Sebenzisa align-itemsizinsiza 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, center, baseline, noma stretch(okuzenzakalelayo kwesiphequluli).
<div class="d-flex align-items-start">...</div>
<div class="d-flex align-items-end">...</div>
<div class="d-flex align-items-center">...</div>
<div class="d-flex align-items-baseline">...</div>
<div class="d-flex align-items-stretch">...</div>Ukuhlukahluka okusabelayo kukhona futhi align-items.
.align-items-start.align-items-end.align-items-center.align-items-baseline.align-items-stretch.align-items-sm-start.align-items-sm-end.align-items-sm-center.align-items-sm-baseline.align-items-sm-stretch.align-items-md-start.align-items-md-end.align-items-md-center.align-items-md-baseline.align-items-md-stretch.align-items-lg-start.align-items-lg-end.align-items-lg-center.align-items-lg-baseline.align-items-lg-stretch.align-items-xl-start.align-items-xl-end.align-items-xl-center.align-items-xl-baseline.align-items-xl-stretch
Qondanisa wena
Sebenzisa align-selfizinsiza 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, end, center, baseline, noma stretch(okuzenzakalelayo kwesiphequluli).
<div class="align-self-start">Aligned flex item</div>
<div class="align-self-end">Aligned flex item</div>

Gcwalisa
Sebenzisa .flex-fillikilasi 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">
<div class="p-2 flex-fill bd-highlight">Flex item with a lot of content</div>
<div class="p-2 flex-fill bd-highlight">Flex item</div>
<div class="p-2 flex-fill bd-highlight">Flex item</div>
</div>Ukuhlukahluka okusabelayo kukhona futhi flex-fill.
.flex-fill.flex-sm-fill.flex-md-fill.flex-lg-fill.flex-xl-fill
Khula ushwabane
Sebenzisa .flex-grow-*izinsiza ukuze uguqule ikhono lento eguquguqukayo ukuze ikhule ukuze ugcwalise isikhala esitholakalayo. Esibonelweni esingezansi, .flex-grow-1izakhi zisebenzisa sonke isikhala esitholakalayo, kuyilapho zivumela izinto ezimbili ezisele eziguquguqukayo zibe indawo yazo edingekayo.
<div class="d-flex bd-highlight">
<div class="p-2 flex-grow-1 bd-highlight">Flex item</div>
<div class="p-2 bd-highlight">Flex item</div>
<div class="p-2 bd-highlight">Third flex item</div>
</div>Sebenzisa .flex-shrink-*izinsiza ukuze uguqule ikhono lento eguquguqukayo ukuze inciphe uma kudingeka. Esibonelweni esingezansi, into yesibili eguquguqukayo nayo .flex-shrink-1iphoqeleka ukuthi isonge okuqukethwe kwayo emugqeni omusha, "ukuncipha" ukuze kuvunyelwe isikhala esengeziwe sento eguquguqukayo yangaphambilini nge- .w-100.
<div class="d-flex bd-highlight">
<div class="p-2 w-100 bd-highlight">Flex item</div>

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 ( .mr-auto), nokusunduza izinto ezimbili kwesokunxele ( .ml-auto).
Ngeshwa, i-IE10 ne-IE11 awawasekeli kahle amamajini azenzakalelayo ezintweni eziguquguqukayo umzali wazo onevelu elingelona elizenzakalelayo justify-content. Bona le mpendulo ye-StackOverflow ukuze uthole imininingwane eyengeziwe.

Ngokuqondile hambisa into eyodwa egobekayo uye phezulu noma phansi esitsheni ngokuxuba align-items, flex-direction: columnnoma .margin-top: automargin-bottom: auto

Shintsha indlela izinto eziguqukayo ezigoqa ngayo esitsheni esiguquguqukayo. Khetha kusukela ekungagoqeni nhlobo (okuzenzakalelayo kwesiphequluli) ngokuthi .flex-nowrap, ukugoqa nge .flex-wrap, noma ukuhlehlisa ukugoqa nge .flex-wrap-reverse.

Oda
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 orderkuthatha noma yiliphi inani eliphelele (isb, 5), engeza i-CSS yangokwezifiso kunoma imaphi amanani engeziwe adingekayo.

Qondanisa okuqukethwe
Sebenzisa align-contentizinsiza eziqukathi ze-flexbox ukuze uqondanise izinto eziguqukayo ndawonye ku-axis enqamulayo. Khetha kokuthi start(okuzenzakalelayo kwesiphequluli), end, center, between, around, noma stretch. Ukuze sibonise lezi zinsiza, siphoqelele flex-wrap: wrapfuthi sandisa inani lezinto eziguqukayo.
Amakhanda phezulu! Lesi sici asinawo umthelela kumugqa owodwa wezinto eziguqukayo.
