reset.css

INFO

Le “ reset CSS ” est une méthode commune de remise à zéro des styles par défaut des différents navigateurs web. Ceci permet de partir d'une base “ saine ” en terme de styles.

Voici ma version personnelle de ce fichier. Il existe autant de versions que de développeuses et développeurs, chacun adaptant son reset.css à ses préférences et/ou habitudes de développement.

J'ai légèrement adaptée le mien depuis la version de Elly Loel.
