Preskoči na glavno vsebino Preskoči na navigacijo po dokumentih

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.

Jaz sem flexbox posoda!
<div class="d-flex p-2 bd-highlight">I'm a flexbox container!</div>
Sem inline flexbox kontejner!
<div class="d-inline-flex p-2 bd-highlight">I'm an inline flexbox container!</div>

Obstajajo tudi odzivne različice za .d-flexin .d-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.

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.

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.

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.

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).

Align content

Use align-content utilities on flexbox containers to align flex items together on the cross axis. Choose from start (browser default), end, center, between, around, or stretch. To demonstrate these utilities, we’ve enforced flex-wrap: wrap and increased the number of flex items.

Heads up! This property has no effect on single rows of flex items.

Media object

Looking to replicate the media object component from Bootstrap 4? Recreate it in no time with a few flex utilities that allow even more flexibility and customization than before.

Placeholder Image
This is some content from a media component. You can replace this with any content and adjust it as needed.
<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>

And say you want to vertically center the content next to the image:
