Flex
Brzo upravljajte rasporedom, poravnanjem i veličinom kolona mreže, navigacijom, komponentama i još mnogo toga s punim paketom prilagodljivih flexbox uslužnih programa. Za složenije implementacije može biti potreban prilagođeni CSS.
Omogućite fleksibilna ponašanja
Primijenite displayuslužne programe za kreiranje flexbox kontejnera i transformirajte direktne podređene elemente u flex stavke. Flex kontejneri i stavke mogu se dalje modificirati s dodatnim flex svojstvima.
<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>Odazivne varijacije također postoje za .d-flexi .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.d-xxl-flex.d-xxl-inline-flex
Smjer
Postavite smjer flex stavki u flex kontejneru s pomoćnim programima za usmjeravanje. U većini slučajeva ovdje možete izostaviti horizontalnu klasu jer je zadana postavka pretraživača row. Međutim, možete naići na situacije u kojima ste trebali eksplicitno postaviti ovu vrijednost (kao što su responzivni izgledi).
Koristite .flex-rowza postavljanje horizontalnog smjera (podrazumevano u pretraživaču) ili .flex-row-reverseza pokretanje horizontalnog smjera sa suprotne strane.
<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="d-flex flex-row-reverse">
<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>Koristite .flex-columnza postavljanje vertikalnog smjera ili .flex-column-reverseza početak vertikalnog smjera sa suprotne strane.
<div class="d-flex flex-column 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="d-flex flex-column-reverse">
<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>Odazivne varijacije također postoje za flex-direction.

Opravdajte sadržaj
Koristite justify-contentuslužne programe na flexbox kontejnerima da promijenite poravnanje flex stavki na glavnoj osi (x-osa za početak, y-osa ako je flex-direction: column). Birajte između start(podrazumevano u pretraživaču), end, center, between, around, ili evenly.
<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>
<div class="d-flex justify-content-evenly">...</div>
Odazivne varijacije također postoje za justify-content.

Poravnajte stavke
Koristite align-itemsuslužne programe na flexbox kontejnerima da promijenite poravnanje flex stavki na poprečnoj osi (y-osa za početak, x-osa ako flex-direction: column). Odaberite između start, end, center, baseline, ili stretch(podrazumevano za pretraživač).
<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>
Odazivne varijacije također postoje za 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.align-items-xxl-start.align-items-xxl-end.align-items-xxl-center.align-items-xxl-baseline.align-items-xxl-stretch
Poravnajte sebe
Koristite align-selfpomoćne programe na flexbox stavkama da pojedinačno promijenite njihovo poravnanje na poprečnoj osi (y-osa za početak, x-osa ako flex-direction: column). Birajte između istih opcija kao align-items: start, end, center, baseline, ili stretch(podrazumevano za pretraživač).
<div class="align-self-start">Aligned flex item</div>
<div class="align-self-end">Aligned flex item</div>
<div class="align-self-center">Aligned flex item</div>
<div class="align-self-baseline">Aligned flex item</div>
<div class="align-self-stretch">Aligned flex item</div>
Odazivne varijacije također postoje za align-self.
.align-self-start.align-self-end.align-self-center.align-self-baseline.align-self-stretch.align-self-sm-start.align-self-sm-end.align-self-sm-center.align-self-sm-baseline.align-self-sm-stretch.align-self-md-start.align-self-md-end.align-self-md-center.align-self-md-baseline.align-self-md-stretch.align-self-lg-start.align-self-lg-end.align-self-lg-center.align-self-lg-baseline.align-self-lg-stretch.align-self-xl-start.align-self-xl-end.align-self-xl-center.align-self-xl-baseline.align-self-xl-stretch.align-self-xxl-start.align-self-xxl-end.align-self-xxl-center.align-self-xxl-baseline.align-self-xxl-stretch
Fill
Koristite .flex-fillklasu na nizu srodnih elemenata da ih natjerate na širine jednake njihovom sadržaju (ili jednake širine ako njihov sadržaj ne premašuje njihove granične okvire) dok zauzimaju sav raspoloživ horizontalni prostor.
<div class="d-flex">
<div class="p-2 flex-fill">Flex item with a lot of content</div>
<div class="p-2 flex-fill">Flex item</div>
<div class="p-2 flex-fill">Flex item</div>
</div>Odazivne varijacije također postoje za flex-fill.
.flex-fill.flex-sm-fill.flex-md-fill.flex-lg-fill.flex-xl-fill.flex-xxl-fill
Raste i smanjuju se
Koristite .flex-grow-*uslužne programe da biste uključili sposobnost fleksibilne stavke da raste kako bi popunila raspoloživi prostor. U primjeru ispod, .flex-grow-1elementi koriste sav raspoloživi prostor koji mogu, dok preostale dvije flex stavke dozvoljavaju njihov neophodan prostor.
<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>Upotrijebite .flex-shrink-*uslužne programe da biste uključili mogućnost smanjenja fleksibilne stavke ako je potrebno. U primjeru ispod, druga flex stavka sa .flex-shrink-1je prisiljena da omota svoj sadržaj u novi red, "smanjujući" se kako bi omogućila više prostora za prethodnu flex stavku sa .w-100.
<div class="d-flex">
<div class="p-2 w-100">Flex item</div>
<div class="p-2 flex-shrink-1">Flex item</div>
</div>Odazivne varijacije također postoje za flex-growi flex-shrink.
.flex-{grow|shrink}-0.flex-{grow|shrink}-1.flex-sm-{grow|shrink}-0.flex-sm-{grow|shrink}-1.flex-md-{grow|shrink}-0.flex-md-{grow|shrink}-1.flex-lg-{grow|shrink}-0.flex-lg-{grow|shrink}-1.flex-xl-{grow|shrink}-0.flex-xl-{grow|shrink}-1.flex-xxl-{grow|shrink}-0.flex-xxl-{grow|shrink}-1
Auto margine
Flexbox može učiniti neke prilično sjajne stvari kada pomiješate fleksibilna poravnanja s automatskim marginama. U nastavku su prikazana tri primjera kontrole flex stavki putem automatskih margina: zadano (bez automatske margine), guranje dvije stavke udesno ( .me-auto) i guranje dvije stavke ulijevo ( .ms-auto).
<div class="d-flex mb-3">
<div class="p-2">Flex item</div>
<div class="p-2">Flex item</div>
<div class="p-2">Flex item</div>
</div>
<div class="d-flex mb-3">
<div class="me-auto p-2">Flex item</div>
<div class="p-2">Flex item</div>
<div class="p-2">Flex item</div>
</div>
<div class="d-flex mb-3">
<div class="p-2">Flex item</div>
<div class="p-2">Flex item</div>
<div class="ms-auto p-2">Flex item</div>
</div>Sa stavkama za poravnanje
Vertikalno pomjerite jednu flex stavku na vrh ili dno spremnika miješanjem align-items, flex-direction: column, i margin-top: autoili margin-bottom: auto.
<div class="d-flex align-items-start flex-column mb-3" style="height: 200px;">
<div class="mb-auto p-2">Flex item</div>
<div class="p-2">Flex item</div>
<div class="p-2">Flex item</div>
</div>
<div class="d-flex align-items-end flex-column mb-3" style="height: 200px;">
<div class="p-2">Flex item</div>
<div class="p-2">Flex item</div>
<div class="mt-auto p-2">Flex item</div>
</div>Zamotajte
Promijenite način umotavanja flex stavki u flex kontejner. Izaberite opciju bez prelamanja (podrazumevano u pretraživaču) sa .flex-nowrap, prelamanje sa .flex-wrapili obrnuto prelamanje sa .flex-wrap-reverse.
<div class="d-flex flex-nowrap">
...
</div>
<div class="d-flex flex-wrap">
...
</div>
<div class="d-flex flex-wrap-reverse">
...
</div>
Odazivne varijacije također postoje za flex-wrap.
.flex-nowrap.flex-wrap.flex-wrap-reverse.flex-sm-nowrap.flex-sm-wrap.flex-sm-wrap-reverse.flex-md-nowrap.flex-md-wrap.flex-md-wrap-reverse.flex-lg-nowrap.flex-lg-wrap.flex-lg-wrap-reverse.flex-xl-nowrap.flex-xl-wrap.flex-xl-wrap-reverse.flex-xxl-nowrap.flex-xxl-wrap.flex-xxl-wrap-reverse
Red
Promijenite vizualni redoslijed određenih flex stavki pomoću nekoliko orderuslužnih programa. Nudimo samo opcije za pravljenje stavke prvi ili zadnji, kao i resetiranje za korištenje DOM reda. Kako orderuzima bilo koju vrijednost cijelog broja od 0 do 5, dodajte prilagođeni CSS za sve potrebne dodatne vrijednosti.
<div class="d-flex flex-nowrap">
<div class="order-3 p-2">First flex item</div>
<div class="order-2 p-2">Second flex item</div>
<div class="order-1 p-2">Third flex item</div>
</div>Odazivne varijacije također postoje za order.
.order-0.order-1.order-2.order-3.order-4.order-5.order-sm-0.order-sm-1.order-sm-2.order-sm-3.order-sm-4.order-sm-5.order-md-0.order-md-1.order-md-2.order-md-3.order-md-4.order-md-5.order-lg-0.order-lg-1.order-lg-2.order-lg-3.order-lg-4.order-lg-5.order-xl-0.order-xl-1.order-xl-2.order-xl-3.order-xl-4.order-xl-5.order-xxl-0.order-xxl-1.order-xxl-2.order-xxl-3.order-xxl-4.order-xxl-5
Osim toga, postoje i responsive .order-firsti .order-lastklase koje mijenjaju orderelement primjenom order: -1i order: 6, respektivno.
.order-first.order-last.order-sm-first.order-sm-last.order-md-first.order-md-last.order-lg-first.order-lg-last.order-xl-first.order-xl-last.order-xxl-first.order-xxl-last
Poravnajte sadržaj
Koristite align-contentpomoćne programe na flexbox kontejnerima da poravnate flex stavke zajedno na poprečnoj osi. Birajte između start(podrazumevano u pretraživaču), end, center, between, around, ili stretch. Da bismo demonstrirali ove uslužne programe, nametnuli smo flex-wrap: wrapi povećali broj flex stavki.
Glavu gore! Ovo svojstvo nema efekta na pojedinačne redove flex stavki.
<div class="d-flex align-content-start flex-wrap">
...
</div>
<div class="d-flex align-content-end flex-wrap">...</div>
<div class="d-flex align-content-center flex-wrap">...</div>
<div class="d-flex align-content-between flex-wrap">...</div>
<div class="d-flex align-content-around flex-wrap">...</div>
<div class="d-flex align-content-stretch flex-wrap">...</div>
Odazivne varijacije također postoje za align-content.
