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.
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.

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.

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.

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).

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).

Uża l- .flex-fillklassi fuq serje ta 'elementi aħwa biex iġġiegħelhom f'wisgħat ugwali filwaqt li tieħu l-ispazju orizzontali disponibbli kollu. Speċjalment utli għan-navigazzjoni b'wisa' ugwali, jew ġustifikata.

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.

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>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.

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.

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.
