Flex
Lawula ngokukhawuleza uyilo, ulungelelwaniso, kunye nobungakanani bekholamu zegridi, ukukhangela, izinto, kunye nokunye okuninzi ngesuti epheleleyo yezixhobo eziphendulayo zebhokisi ye-flexibox. Ukuphunyezwa okuntsonkothileyo ngakumbi, iCSS yesiko ingafuneka.
Nika amandla ukuziphatha okuguquguqukayo
Faka displayizinto eziluncedo ukwenza isikhongozeli se-flexbox kwaye uguqule izinto ezithe ngqo zabantwana zibe zizinto eziguqukayo. Izikhongozeli zeFlex kunye nezinto ziyakwazi ukuguqulwa ngakumbi ngeempawu ezongezelelweyo ze-flex.
<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>Iiyantlukwano eziphendulayo zikwakhona .d-flexkwaye .d-inline-flex.

Isalathiso
Seta icala lezinto eziguquguqukayo kwisikhongozeli esine-flex esineendlela eziluncedo. Kwiimeko ezininzi ungashiya udidi oluthe tye apha njengoko umkhangeli zincwadi ongagqibekanga unjalo row. Nangona kunjalo, ungadibana neemeko apho ubufuna ukuseta ngokuthe gca eli xabiso (njengoyilo oluphendulayo).
Sebenzisa .flex-rowukuseta isalathiso esithe tye (isikhangeli esingagqibekanga), okanye .flex-row-reverseukuqalisa ulwalathiso oluthe tye ukusuka kwelinye icala.
<div class="d-flex flex-row bd-highlight mb-3">

Lungelelanisa izinto
Sebenzisa align-itemsizinto eziluncedo kwizikhongozeli zeflexbox ukutshintsha ulungelelwaniso lwezinto eziguqukayo kwi-axis enqamlezileyo (umgca ongu-y ukuqalisa, u-x-axis ukuba flex-direction: column). Khetha kwi start, end, center, baseline, okanye stretch(ukungagqibeki kwesikhangeli).
<div class="d-flex align-items-start">...</div>
