I-Flex

Ngokushesha phatha ukwakheka, ukuqondanisa, nosayizi wamakholomu egridi, ukuzulazula, izingxenye, nokunye okwengeziwe ngohlelo olugcwele lwezinsiza eziphendulayo ze-flexbox. Ukuze uthole ukuqaliswa okuyinkimbinkimbi, i-CSS yangokwezifiso ingase idingeke.

Nika amandla ukuziphatha okuguquguqukayo

Sebenzisa displayizinsiza ukuze udale isiqukathi se-flexbox futhi uguqule izici zezingane eziqondile zibe izinto eziguqukayo. Iziqukathi ze-Flex nezinto ziyakwazi ukuguqulwa ngokuqhubekayo ngezakhiwo ezengeziwe eziguqukayo.

Isiqondiso

Setha isiqondiso sezinto eziguqukayo esitsheni esiguquguqukayo esinezinsiza zokuqondisa. Ezimweni eziningi ungashiya isigaba esivundlile lapha njengoba okuzenzakalelayo kwesiphequluli kuyi- row. Nokho, ungase uhlangabezane nezimo lapho ubudinga ukusetha ngokusobala leli nani (njengezakhiwo eziphendulayo).

Sebenzisa .flex-rowukusetha isiqondiso esivundlile (okuzenzakalelayo kwesiphequluli), noma .flex-row-reverseukuqala indawo evundlile ukusuka kolunye uhlangothi.

Lungiselela okuqukethwe

Sebenzisa justify-contentizinsiza ezitsheni ze-flexbox ukuze uguqule ukuqondanisa kwezinto eziguqukayo ku-eksisi eyinhloko (i-eksisi engu-x ezoqala, i-eksisi engu-y uma flex-direction: column). Khetha kokuthi start(okuzenzakalelayo kwesiphequluli), end, center, between, noma around.

Amamajini azenzakalelayo

I-Flexbox ingenza izinto ezinhle kakhulu uma uhlanganisa ukuqondanisa okuguquguqukayo namamajini azenzakalelayo. Okuboniswe ngezansi izibonelo ezintathu zokulawula izinto eziguqukayo usebenzisa amamajini azenzakalelayo: okuzenzakalelayo (ayikho imajini ezenzakalelayo), ukusunduza izinto ezimbili kwesokudla ( .mr-auto), nokusunduza izinto ezimbili kwesokunxele ( .ml-auto).

Ngeshwa, i-IE10 ne-IE11 awawasekeli kahle amamajini azenzakalelayo ezintweni eziguquguqukayo umzali wazo onevelu elingelona elizenzakalelayo justify-content. Bona le mpendulo ye-StackOverflow ukuze uthole imininingwane eyengeziwe.
