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.
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.

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 ( .mr-auto), ak pouse de atik sou bò gòch la ( .ml-auto).
Malerezman, IE10 ak IE11 pa byen sipòte maj oto sou atik flex ki gen paran yo gen yon justify-contentvalè ki pa defo. Gade repons StackOverflow sa a pou plis detay.
