Flex, un exemple de grille

Créer une grille à partir de la propriété display: flex

Voici un exemple de grille flex, trouvée sur le CodePen de Ruslan Pivovarov.

Reprenant la logique bootstrap, elle comporte la base d’une disposition en 12 colonnes et permet de structurer sa page très facilement. Pour l’utiliser, il faut se servir du « container » pour englober son contenu. A l’intérieur on glisse autant de row que nécessaire. Et dans celles-ci, on glisse nos colonnes en se servant des classes flex-col-xs, flex-col-sm, flex-col-md, et flex-col-lg. Ce code peut être modifié, amélioré et on peut y ajouter toutes les autres classes utiles de bootstrap pour en faire son propre framework css de base !
