Rjochting
Stel de rjochting fan flex items yn in flex container mei rjochting nutsbedriuwen. Yn 'e measte gefallen kinne jo hjir de horizontale klasse weilitte, om't de browser standert is row. Jo kinne lykwols situaasjes tsjinkomme wêr't jo dizze wearde eksplisyt moatte ynstelle (lykas responsive layouts).
Brûk .flex-rowom in horizontale rjochting yn te stellen (de browser standert), of .flex-row-reverseom de horizontale rjochting fan 'e tsjinoerstelde kant te begjinnen.

Brûk de .flex-fillklasse op in searje sibling-eleminten om se yn breedtes te twingen dy't lykweardich binne oan har ynhâld (of gelikense breedtes as har ynhâld har grinsdoazen net oerkomt) wylst se alle beskikbere horizontale romte opnimme.
<div class="d-flex">

Groei en krimp
Brûk .flex-grow-*nutsbedriuwen om it fermogen fan in flex-item te wikseljen om te groeien om beskikbere romte te foljen. Yn it foarbyld hjirûnder .flex-grow-1brûke de eleminten alle beskikbere romte dy't it kin, wylst de oerbleaune twa flexitems harren nedige romte tastean.
<div class="d-flex">

<div class="p-2">Third flex item</div>
</div>Brûk .flex-shrink-*nutsbedriuwen om it fermogen fan in flex-item te wikseljen om as nedich te krimp. Yn it foarbyld hjirûnder, de twadde flex item mei .flex-shrink-1wurdt twongen om wrap syn ynhâld nei in nije rigel, "krimpen" foar in tastean mear romte foar de foarige flex item mei .w-100.

Auto marzjes
Flexbox kin wat moaie geweldige dingen dwaan as jo flex-ôfstimmingen mingje mei automarzjes. Hjirûnder werjûn trije foarbylden fan it kontrolearjen fan flex items fia auto marzjes: standert (gjin auto marzje), triuwe twa items nei rjochts ( .me-auto), en triuwe twa items nei lofts ( .ms-auto).
<div class="d-flex mb-3">

<div class="ms-auto p-2">Flex item</div>
</div>Mei align-items
Fertikaal ferpleatse ien flex-item nei de boppe- of ûnderkant fan in kontener troch te mingjen align-items, flex-direction: column, en margin-top: autoof margin-bottom: auto.

Brûk align-contentnutsbedriuwen op flexbox-konteners om flex-items tegearre op 'e krúsas út te rjochtsjen. Kies út start(standert browser), end, center, between, around, of stretch. Om dizze nutsfoarsjenningen te demonstrearjen, hawwe wy flex-wrap: wrapit oantal flexitems hanthavene en ferhege.
Heads up! Dit pân hat gjin effekt op inkele rigen fan flex items.
