Flex
Kudeatu azkar sareko zutabeen, nabigazioaren, osagaien eta besteren diseinua, lerrokatzea eta dimentsioa flexbox erreaktiboen multzo oso batekin. Inplementazio konplexuagoetarako, CSS pertsonalizatua beharrezkoa izan daiteke.

utilitateak flexbox edukiontzi bat sortzeko eta zuzeneko haurren elementuak elementu flex bihurtzeko. Flex ontziak eta elementuak gehiago alda daitezke flex propietate gehigarriekin.

Norabidea
Ezarri elementu malgutuen norabidea norabide utilitateekin flexu-edukiontzi batean. Kasu gehienetan, klase horizontala ezaba dezakezu hemen arakatzailearen lehenetsia baita row
. Hala ere, baliteke balio hori esplizituki ezarri behar zenuten egoerak aurkitzea (diseinu erantzuleak adibidez).
Erabili .flex-row
norabide horizontala ezartzeko (arakatzailearen lehenetsia) edo .flex-row-reverse
norabide horizontala kontrako aldean hasteko.
<div class="d-flex flex-row bd-highlight mb-3">
