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

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>

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>

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).

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.

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 igoqe okuqukethwe emugqeni omusha, “ukuncipha” ukuze kuvunyelwe isikhala esengeziwe sento eguquguqukayo yangaphambilini ngokuthi .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 ( .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.

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.
