Font Awesome Icons are incredibly awesome. Avada has them built right into the theme so you can use any of the 300+ icons. Each one comes in 3 sizes and can be used with or without a circle and every one is 100{2ab371679fa3269c4cffbb8808b413c43f74aa932f2d7a47c22bb2417d1b105d} full vector so they look incredibly sharp and are retina-ready!
