Flexbox en CSS CSS35

Solution du HTML

Pour cet exercice, nous utilisons plusieurs classes pour chaque élément. Cette technique permet de limiter les répétitions de code.

Nous allons réunir sous une classe générique les propriétés de mise en forme communes aux différents éléments avec les classes container et item. Puis nous allons régler les spécificités des éléments avec des classes spécifiques item-a, item-b, item-c et item-d.

La classe container-1 n’a pas d’intérêt pour le moment mais nous permettra de traiter la question suivante en ajoutant des propriété de mise en forme spécifiques.

<div class="container container-1">
  <div class="item item-a">A</div>
  <div class="item item-b">B</div>
  <div class="item item-c">C</div>
  <div class="item item-d">D</div>
</div>
