Flex
Stiùirich gu sgiobalta cruth, co-thaobhadh, agus meud colbhan clèithe, seòladh, co-phàirtean, agus barrachd le làn shreath de ghoireasan flexbox freagairteach. Airson buileachadh nas iom-fhillte, is dòcha gum bi feum air CSS àbhaisteach.
Cuir a-steach displaygoireasan gus inneal bogsa flex a chruthachadh agus atharraich eileamaidean cloinne dìreach gu bhith nan nithean sùbailte. Faodar soithichean sùbailte agus nithean atharrachadh tuilleadh le feartan sùbailte a bharrachd.
<div class="d-flex p-2">I'm a flexbox container!</div><div class="d-inline-flex p-2">I'm an inline flexbox container!</div>Tha eadar-dhealachaidhean freagairteach ann cuideachd airson .d-flexagus .d-inline-flex.

Suidhich stiùireadh nithean sùbailte ann an soitheach sùbailte le goireasan stiùiridh. Anns a’ mhòr-chuid de chùisean faodaidh tu an clas còmhnard fhàgail air falbh an seo oir is e row. Ach, is dòcha gun tig thu tarsainn air suidheachaidhean far am feumadh tu an luach seo a shuidheachadh gu soilleir (leithid cruth freagairteach).
Cleachd .flex-rowgus stiùireadh còmhnard a shuidheachadh (bunaiteach a’ bhrabhsair), no .flex-row-reversegus an t-slighe chòmhnard a thòiseachadh bhon taobh eile.

Cleachd justify-contentgoireasan air soithichean flexbox gus co-thaobhadh nithean sùbailte air a’ phrìomh axis atharrachadh (an x-axis airson tòiseachadh, y-axis ma tha flex-direction: column). Tagh bho start(brabhsair bunaiteach), end, center, , between, no around.

Tagh bho na h-aon roghainnean ri align-items: start, end, , , center, baseline, no stretch(àbhaisteach brabhsair).

Faodaidh Flexbox rudan gu math uamhasach a dhèanamh nuair a bhios tu a’ measgachadh co-thaobhadh sùbailte le oirean fèin-ghluasadach. Gu h-ìosal tha trì eisimpleirean de bhith a’ cumail smachd air nithean sùbailte tro iomaill fèin-ghluasadach: bunaiteach (gun iomall fèin-ghluasadach), a’ putadh dà rud air an taobh cheart ( .mr-auto), agus a’ putadh dà rud air an taobh chlì ( .ml-auto).
Gu mì-fhortanach, chan eil IE10 agus IE11 a’ toirt taic cheart do iomaill chàraichean air nithean sùbailte aig a bheil justify-contentluach neo-àbhaisteach aig a phàrant. Faic am freagairt StackOverflow seo airson tuilleadh fiosrachaidh.

Atharraich òrdugh lèirsinneach nithean sùbailte sònraichte le dòrlach de orderghoireasan. Cha toir sinn seachad ach roghainnean airson rud a dhèanamh an toiseach no mu dheireadh, a bharrachd air ath-shuidheachadh gus an òrdugh DOM a chleachdadh. Mar ordera bheir luach iomlan sam bith (me, 5), cuir CSS àbhaisteach airson luachan a bharrachd a tha a dhìth.

Cleachd align-contentgoireasan air soithichean flexbox gus nithean sùbailte a cho-thaobhadh ri chèile air a’ chrois-axis. Tagh bho start(brabhsair bunaiteach), end, center, , between, around, no stretch. Gus na goireasan sin a nochdadh, tha sinn air flex-wrap: wrapan àireamh de nithean sùbailte a chuir an gnìomh agus àrdachadh.
Cinn suas! Chan eil buaidh sam bith aig an togalach seo air sreathan singilte de nithean sùbailte.
