Flex
Byen vit jere layout, aliyman, ak gwosè kolòn kadriyaj, navigasyon, konpozan, ak plis ankò ak yon seri konplè sèvis piblik flexbox ki reponn. Pou aplikasyon ki pi konplèks, CSS koutim ka nesesè.
Pèmèt konpòtman flex
Aplike displaysèvis piblik yo pou kreye yon veso flexbox ak transfòme eleman dirèk timoun yo nan atik flex. Kontenè Flex ak atik yo kapab modifye pi lwen ak pwopriyete fleksib adisyonèl.

Direksyon
Mete direksyon atik flex nan yon veso flex ak sèvis piblik direksyon. Nan pifò ka yo, ou ka omisyon klas orizontal isit la kòm default navigatè a se row. Sepandan, ou ka rankontre sitiyasyon kote ou te bezwen klèman mete valè sa a (tankou kouman reponn).
Sèvi ak .flex-rowyo mete yon direksyon orizontal (defo navigatè a), oswa .flex-row-reverseyo kòmanse direksyon orizontal la soti nan bò opoze a.

Ranpli
Sèvi ak .flex-fillklas la sou yon seri eleman frè ak sè pou fòse yo nan lajè ki egal ak kontni yo (oswa lajè egal si kontni yo pa depase bwat fwontyè yo) pandan y ap pran tout espas orizontal ki disponib.

Grandi ak retresi
Sèvi ak .flex-grow-*sèvis piblik pou chanje kapasite yon atik flex pou grandi pou ranpli espas ki disponib. Nan egzanp ki anba a, .flex-grow-1eleman yo sèvi ak tout espas ki disponib li kapab, pandan y ap pèmèt rès de atik fleksib espas ki nesesè yo.

<div class="p-2">Third flex item</div>
</div>Sèvi ak .flex-shrink-*sèvis piblik pou activer kapasite yon atik flex pou retresi si sa nesesè. Nan egzanp ki anba la a, dezyèm atik flex .flex-shrink-1la oblije vlope sa ki ladan l nan yon nouvo liy, ki "retresi" pou pèmèt plis espas pou atik flex anvan an ak .w-100.

Marge oto
Flexbox ka fè kèk bagay trè awizom lè ou melanje aliyman flex ak maj oto. Yo montre anba a twa egzanp kontwole atik flex atravè maj oto: default (pa gen maj oto), pouse de atik sou bò dwat la ( .me-auto), ak pouse de atik sou bò gòch la ( .ms-auto).

Chanje lòd vizyèl atik fleksib espesifik ak yon ti ponyen ordersèvis piblik. Nou sèlman bay opsyon pou fè yon atik premye oswa dènye, osi byen ke yon reset pou itilize lòd DOM la. Kòm orderpran nenpòt valè nonb antye relatif soti nan 0 a 5, ajoute CSS koutim pou nenpòt valè adisyonèl ki nesesè.

Sèvi ak align-contentsèvis piblik sou resipyan flexbox pou fè aliman atik flex ansanm sou aks kwa a. Chwazi nan start(defo navigatè), end, center, between, around, oswa stretch. Pou demontre sèvis piblik sa yo, nou te ranfòse flex-wrap: wrapak ogmante kantite atik flex.
Tèt leve! Pwopriyete sa a pa gen okenn efè sou yon sèl ranje atik flex.
