  • ➡️ utiliser une balise <img>
• Si l’icone est utilisée plusieurs fois,
• Si l’icone est critique
  • ➡️ utiliser des Inline SVG Symbol
• Si l’icone n’est pas critique,
  • S’il est possible d’héberger du SVG sur votre propre domaine
    • ➡️ utiliser des Remote SVG Symbol
  • Si non,
    • ➡️ Essayez de convaincre très fort votre admin sys de l’importance d’avoir le même domaine pour vos assets
    • ➡️ Ou passez par un fallback avec des CSS mask
    • ➡️ Ou utilisez des Inline SVG Symbol
• Si vous utilisez une font d’icone,

The rel attribute defines a relationship between the linked resources (one being the document it appears on). And it provides that relationship with meaning, creating a semantic network where the different pieces have a role and a purpose.

Also, savvy web developers can use it to make friendlier sites–we’ll see some examples in the following sections.
