Fflecs
Rheoli cynllun, aliniad a maint colofnau grid, llywio, cydrannau, a mwy yn gyflym gyda chyfres lawn o gyfleustodau flexbox ymatebol. Ar gyfer gweithrediadau mwy cymhleth, efallai y bydd angen CSS personol.
Galluogi ymddygiadau hyblyg
Cymhwyso displaycyfleustodau i greu cynhwysydd flexbox a thrawsnewid elfennau uniongyrchol plant yn eitemau hyblyg. Gellir addasu cynwysyddion ac eitemau hyblyg ymhellach gydag eiddo fflecs ychwanegol.
<div class="d-flex p-2 bd-highlight">I'm a flexbox container!</div><div class="d-inline-flex p-2 bd-highlight">I'm an inline flexbox container!</div>Mae amrywiadau ymatebol hefyd yn bodoli ar gyfer .d-flexa .d-inline-flex.

Cyfeiriad
Gosodwch gyfeiriad eitemau fflecs mewn cynhwysydd fflecs gyda chyfleustodau cyfeiriad. Yn y rhan fwyaf o achosion gallwch hepgor y dosbarth llorweddol yma gan mai rhagosodiad y porwr yw row. Fodd bynnag, efallai y byddwch yn dod ar draws sefyllfaoedd lle roedd angen i chi osod y gwerth hwn yn benodol (fel cynlluniau ymatebol).
Defnyddiwch .flex-rowi osod cyfeiriad llorweddol (rhagosodiad y porwr), neu .flex-row-reversei gychwyn y cyfeiriad llorweddol o'r ochr arall.

Tyfu a chrebachu
Defnyddiwch .flex-grow-*gyfleustodau i newid gallu eitem fflecs i dyfu i lenwi'r gofod sydd ar gael. Yn yr enghraifft isod, mae'r .flex-grow-1elfennau'n defnyddio'r holl le sydd ar gael y gall, tra'n caniatáu gofod angenrheidiol i'r ddwy eitem hyblyg sy'n weddill.

<div class="p-2 bd-highlight">Third flex item</div>
</div>Defnyddiwch .flex-shrink-*gyfleustodau i newid gallu eitem fflecs i grebachu os oes angen. Yn yr enghraifft isod, mae'r ail eitem hyblyg .flex-shrink-1yn cael ei gorfodi i lapio ei chynnwys i linell newydd, gan “grebachu” i ganiatáu mwy o le ar gyfer yr eitem fflecs flaenorol gyda .w-100.

Ymylon Auto
Gall Flexbox wneud rhai pethau eithaf anhygoel pan fyddwch chi'n cymysgu aliniadau fflecs ag ymylon ceir. Isod mae tair enghraifft o reoli eitemau hyblyg trwy ymylon ceir: rhagosodiad (dim ymyl auto), gwthio dwy eitem i'r dde ( .me-auto), a gwthio dwy eitem i'r chwith ( .ms-auto).
<div class="d-flex bd-highlight mb-3">

Symudwch un eitem fflecs yn fertigol i ben neu waelod cynhwysydd trwy gymysgu align-items, flex-direction: column, a margin-top: autoneu margin-bottom: auto.
<div class="d-flex align-items-start flex-column bd-highlight mb-3" style="height: 200px;">

<div class="mt-auto p-2 bd-highlight">Flex item</div>
</div>Lapiwch
Newid sut mae eitemau fflecs yn lapio mewn cynhwysydd fflecs. Dewiswch o ddim lapio o gwbl (y porwr rhagosodedig) gyda .flex-nowrap, lapio gyda .flex-wrap, neu wrthdroi lapio gyda .flex-wrap-reverse.
<div class="d-flex flex-nowrap">

Gorchymyn
Newidiwch drefn weledol eitemau hyblyg penodol gyda llond llaw o ordergyfleustodau. Rydym ond yn darparu opsiynau ar gyfer gwneud eitem yn gyntaf neu'n olaf, yn ogystal ag ailosodiad i ddefnyddio'r archeb DOM. Gan ordergymryd unrhyw werth cyfanrif o 0 i 5, ychwanegwch CSS personol ar gyfer unrhyw werthoedd ychwanegol sydd eu hangen.

Alinio cynnwys
Defnyddiwch align-contentgyfleustodau ar gynwysyddion flexbox i alinio eitemau fflecs gyda'i gilydd ar yr echel groes. Dewiswch o start(diofyn porwr), end, center, , between, around, neu stretch. Er mwyn dangos y cyfleustodau hyn, rydym wedi gorfodi flex-wrap: wrapa chynyddu nifer yr eitemau hyblyg.
Pennau i fyny! Nid yw'r eiddo hwn yn cael unrhyw effaith ar resi sengl o eitemau fflecs.
