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 bd-highlight">
<div class="p-2 flex-fill bd-highlight">Flex item with a lot of content</div>

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 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>Brûk .flex-shrink-*nutsbedriuwen om de mooglikheid fan in flex-item te wikseljen om te krimpen as nedich. 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 aardich 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 bd-highlight mb-3">

Wy jouwe allinich opsjes foar it meitsjen fan in item earst as lêste, lykas ek in reset om de DOM-oarder te brûken. As ordernimt eltse integer wearde fan 0 oan 5, add custom CSS foar alle ekstra wearden nedich.
<div class="d-flex flex-nowrap bd-highlight">

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.
