Flex
Immaniġġja malajr it-tqassim, l-allinjament, u d-daqs tal-kolonni tal-grilja, in-navigazzjoni, il-komponenti, u aktar b'firxa sħiħa ta 'utilitajiet tal-flexbox li jirrispondu. Għal implimentazzjonijiet aktar kumplessi, CSS personalizzat jista 'jkun meħtieġ.
Jippermettu imgieba flex
Applika displayutilitajiet biex toħloq kontenitur flexbox u tittrasforma elementi diretti tat-tfal f'oġġetti flex. Il-kontenituri u l-oġġetti Flex jistgħu jiġu modifikati aktar bi proprjetajiet flex addizzjonali.
<div class="d-flex p-2 bd-highlight">I'm a flexbox container!</div><div class="d-inline-flex p-2 bd-highlight">I'm an inline flexbox container!</div>Jeżistu wkoll varjazzjonijiet li jirrispondu għal .d-flexu .d-inline-flex.

Direzzjoni
Issettja d-direzzjoni ta 'oġġetti flex f'kontenitur flex b'utilitajiet ta' direzzjoni. Fil-biċċa l-kbira tal-każijiet tista' tħalli barra l-klassi orizzontali hawnhekk peress li d-default tal-browser huwa row. Madankollu, tista' tiltaqa' ma' sitwazzjonijiet fejn kellek bżonn tissettja dan il-valur b'mod espliċitu (bħal layouts li jirrispondu).
Uża .flex-rowbiex tissettja direzzjoni orizzontali (il-browser default), jew .flex-row-reversebiex tibda d-direzzjoni orizzontali min-naħa opposta.
<div class="d-flex flex-row bd-highlight mb-3">

<div class="p-2 bd-highlight">Flex item 1</div>
<div class="p-2 bd-highlight">Flex item 2</div>
<div class="p-2 bd-highlight">Flex item 3</div>
</div>Uża .flex-columnbiex tissettja direzzjoni vertikali, jew .flex-column-reversebiex tibda d-direzzjoni vertikali min-naħa opposta.
<div class="d-flex flex-column bd-highlight mb-3">
<div class="p-2 bd-highlight">Flex item 1</div>

Iġġustifika l-kontenut
Uża justify-contentutilitajiet fuq kontenituri flexbox biex tbiddel l-allinjament ta 'oġġetti flex fuq l-assi prinċipali (l-assi x biex tibda, l-assi y jekk flex-direction: column). Agħżel minn start(default tal-browser), end, center, between, jew around.

Allinja l-oġġetti
Uża align-itemsutilitajiet fuq kontenituri flexbox biex tbiddel l-allinjament ta 'oġġetti flex fuq l-assi trasversali (l-assi y biex tibda, l-assi x jekk flex-direction: column). Agħżel minn start, end, center, baseline, jew stretch(default tal-browser).
<div class="d-flex align-items-start">...</div>

Tallinja ruħha
Uża align-selfutilitajiet fuq oġġetti tal-flexbox biex tbiddel individwalment l-allinjament tagħhom fuq l-assi trasversali (l-assi y biex tibda, l-assi x jekk flex-direction: column). Agħżel mill-istess għażliet bħal align-items: start, end, center, baseline, jew stretch(default tal-browser).
<div class="align-self-start">Aligned flex item</div>
<div class="align-self-end">Aligned flex item</div>

Imla
Uża l- .flex-fillklassi fuq serje ta 'elementi aħwa biex iġġiegħelhom f'wisgħat ugwali għall-kontenut tagħhom (jew wisgħat ugwali jekk il-kontenut tagħhom ma jaqbiżx il-kaxxi tal-fruntiera tagħhom) filwaqt li tieħu l-ispazju orizzontali disponibbli kollu.
<div class="d-flex bd-highlight">
<div class="p-2 flex-fill bd-highlight">Flex item with a lot of content</div>
<div class="p-2 flex-fill bd-highlight">Flex item</div>
<div class="p-2 flex-fill bd-highlight">Flex item</div>
</div>Jeżistu wkoll varjazzjonijiet li jirrispondu għal flex-fill.
.flex-fill.flex-sm-fill.flex-md-fill.flex-lg-fill.flex-xl-fill
Ikber u tiċkien
Uża .flex-grow-*l-utilitajiet biex taqleb il-kapaċità ta 'oġġett flex li jikber biex timla l-ispazju disponibbli. Fl-eżempju hawn taħt, l- .flex-grow-1elementi jużaw l-ispazju kollu disponibbli li jistgħu, filwaqt li jippermettu liż-żewġ oġġetti flex li jifdal l-ispazju meħtieġ tagħhom.
<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>Uża .flex-shrink-*l-utilitajiet biex taqleb il-kapaċità ta 'oġġett flex li tiċkien jekk meħtieġ. Fl-eżempju t'hawn taħt, it-tieni oġġett flex ma .flex-shrink-1huwa sfurzat biex ikebbeb il-kontenut tiegħu għal linja ġdida, "tiċkien" biex jippermetti aktar spazju għall-oġġett flex preċedenti b' .w-100.
<div class="d-flex bd-highlight">
<div class="p-2 w-100 bd-highlight">Flex item</div>
<div class="p-2 flex-shrink-1 bd-highlight">Flex item</div>
</div>Jeżistu wkoll varjazzjonijiet li jirrispondu għal flex-growu flex-shrink.

Marġini awtomatiċi
Flexbox jista 'jagħmel xi affarijiet pjuttost tal-biża' meta tħallat allinjamenti flex ma 'marġini awtomatiċi. Hawn taħt jidhru tliet eżempji ta 'kontroll ta' oġġetti flex permezz ta 'marġini awtomatiċi: default (l-ebda marġni awtomatika), imbuttar żewġ oġġetti lejn il-lemin ( .mr-auto), u imbuttar żewġ oġġetti lejn ix-xellug ( .ml-auto).
Sfortunatament, IE10 u IE11 ma jappoġġjawx sew il-marġini awtomatiċi fuq oġġetti flex li l-ġenitur tagħhom għandu valur mhux default justify-content. Ara din it-tweġiba StackOverflow għal aktar dettalji.

</div>Bil-allinjament-oġġetti
Mexxi oġġett wieħed flex b'mod vertikali lejn il-parti ta' fuq jew t'isfel ta' kontenitur billi tħallat align-items, flex-direction: column, u margin-top: autojew margin-bottom: auto.

</div>Kebbeb
Ibdel kif l-oġġetti flex jkebbew f'kontenitur flex. Agħżel minn ebda tgeżwir (l-default tal-brawżer) bi .flex-nowrap, tgeżwir bi .flex-wrap, jew tgeżwir b'lura b' .flex-wrap-reverse.

Ordni
Ibdel l -ordni viżwali ta 'oġġetti flex speċifiċi b'numru żgħir ta' orderutilitajiet. Aħna nipprovdu biss għażliet biex nagħmlu oġġett l-ewwel jew l-aħħar, kif ukoll reset biex tuża l-ordni DOM. Kif orderjieħu kwalunkwe valur sħiħ (eż, 5), żid CSS personalizzat għal kwalunkwe valuri addizzjonali meħtieġa.

Allinja l-kontenut
Uża align-contentutilitajiet fuq kontenituri flexbox biex tallinja l-oġġetti flex flimkien fuq l-assi trasversali. Agħżel minn start(default tal-browser), end, center, between, around, jew stretch. Biex nuru dawn l-utilitajiet, inforzajna u żidna flex-wrap: wrapn-numru ta 'oġġetti flex.
Irjus up! Din il-proprjetà m'għandha l-ebda effett fuq ringieli singoli ta' oġġetti flex.
