Flex
Hitro upravljajte postavitev, poravnavo in velikost mrežnih stolpcev, navigacijo, komponente in več s polno zbirko odzivnih pripomočkov flexbox. Za bolj zapletene izvedbe bo morda potreben CSS po meri.
Omogoči prilagodljiva vedenja
Uporabite displaypripomočke za ustvarjanje vsebnika flexbox in preoblikovanje neposrednih podrejenih elementov v elemente flex. Flex vsebnike in predmete je mogoče dodatno spreminjati z dodatnimi lastnostmi 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>Obstajajo tudi odzivne različice za .d-flexin .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
Smer
Nastavite smer elementov flex v vsebniku flex s pripomočki za usmerjanje. V večini primerov lahko vodoravni razred tukaj izpustite, saj je brskalnik privzeto nastavljen row. Vendar pa lahko naletite na situacije, ko morate izrecno nastaviti to vrednost (kot so odzivne postavitve).
Uporabite .flex-rowza nastavitev vodoravne smeri (privzeta nastavitev brskalnika) ali .flex-row-reverseza začetek vodoravne smeri z nasprotne strani.
<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>Uporabite .flex-columnza nastavitev navpične smeri ali .flex-column-reverseza začetek navpične smeri z nasprotne strani.
<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>

Utemelji vsebino
Uporabite justify-contentpripomočke na vsebnikih flexbox, da spremenite poravnavo elementov flex na glavni osi (os x za začetek, os y, če flex-direction: column). Izberite med start(privzeto v brskalniku), end, center, between, aroundali 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>

Poravnajte elemente
Uporabite align-itemspripomočke na vsebnikih flexbox, da spremenite poravnavo elementov flex na prečni osi (os y za začetek, os x, če flex-direction: column). Izberite med start, end, center, baselineali stretch(privzeto v brskalniku).
<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>
Odzivne različice obstajajo tudi za align-items.

Poravnajte se
Uporabite align-selfpripomočke na elementih flexbox, da posamezno spremenite njihovo poravnavo na prečni osi (os y za začetek, os x, če flex-direction: column). Izberite med enakimi možnostmi kot align-items: start, end, center, baseline, ali stretch(privzeto v brskalniku).
<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>

Izpolnite
Uporabite .flex-fillrazred na nizu sorodnih elementov, da jih prisilite v širine, ki so enake njihovi vsebini (ali enake širine, če njihova vsebina ne presega njihovih obrobnih polj), hkrati pa zavzamejo ves razpoložljivi vodoravni 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>Odzivne različice obstajajo tudi za flex-fill.
.flex-fill.flex-sm-fill.flex-md-fill.flex-lg-fill.flex-xl-fill.flex-xxl-fill
Rasti in se krči
Uporabite .flex-grow-*pripomočke za preklop zmožnosti elementa flex, da raste, da zapolni razpoložljivi prostor. V spodnjem primeru .flex-grow-1elementi uporabijo ves razpoložljivi prostor, ki ga lahko, medtem ko preostalima dvema prilagodljivima elementoma omogočijo potreben 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>Uporabite .flex-shrink-*pripomočke za preklop zmožnosti elementa flex, da se po potrebi skrči. V spodnjem primeru je drugi gibljivi element z .flex-shrink-1prisiljen zaviti svojo vsebino v novo vrstico in se »skrči«, da omogoči več prostora za prejšnji gibljivi element z .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>Obstajajo tudi odzivne različice za flex-growin 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
Samodejne marže
Flexbox lahko naredi nekaj precej osupljivih stvari, ko mešate upogibne poravnave s samodejnimi robovi. Spodaj so prikazani trije primeri nadzora prilagodljivih elementov prek samodejnih robov: privzeto (brez samodejnega roba), potiskanje dveh elementov v desno ( .me-auto) in potiskanje dveh elementov v levo ( .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>Z align-items
Navpično premaknite en upogljivi predmet na vrh ali dno posode z mešanjem align-items, flex-direction: columnin margin-top: autoali 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>Ovitek
Spremenite način zavijanja predmetov flex v vsebniku flex. Izbirate lahko med nikakršnim prelivanjem (privzeto v brskalniku) z .flex-nowrap, prelivanjem z .flex-wrapali obratnim prelivanjem z .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>
Odzivne različice obstajajo tudi za flex-wrap.

naročilo
Spremenite vizualni vrstni red določenih elementov flex s peščico orderpripomočkov. Nudimo samo možnosti za izdelavo elementa prvega ali zadnjega ter ponastavitev za uporabo vrstnega reda DOM. Ker ordersprejme katero koli celo število od 0 do 5, dodajte CSS po meri za vse potrebne dodatne vrednosti.
<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>Odzivne različice obstajajo tudi 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
Poleg tega obstajajo tudi odzivni razredi .order-firstin .order-lastrazredi, ki spreminjajo orderelement z uporabo order: -1oziroma order: 6.

Uskladite vsebino
Uporabite align-contentpripomočke na vsebnikih flexbox, da poravnate elemente flex skupaj na prečni osi. Izberite med start(privzeto v brskalniku), end, center, between, aroundali stretch. Za predstavitev teh pripomočkov smo uveljavili flex-wrap: wrapin povečali število prilagodljivih elementov.
Glavo pokonci! Ta lastnost ne vpliva na posamezne vrstice prilagodljivih elementov.
<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>

Medijski predmet
Želite ponoviti komponento medijskega predmeta iz Bootstrapa 4? Ponovno ga ustvarite v hipu z nekaj pripomočki flex, ki omogočajo še večjo prilagodljivost in prilagajanje kot prej.
<div class="d-flex">
<div class="flex-shrink-0">
<img src="..." alt="...">
</div>
<div class="flex-grow-1 ms-3">
This is some content from a media component. You can replace this with any content and adjust it as needed.
</div>
</div>In recimo, da želite navpično sredinsko vsebino poleg slike:
<div class="d-flex align-items-center">
<div class="flex-shrink-0">
<img src="..." alt="...">
</div>
<div class="flex-grow-1 ms-3">
This is some content from a media component. You can replace this with any content and adjust it as needed.
