We decided to use SCSS to create Chitchat, and to keep things clear, we decided to use our own methodology called Light BEM

• Chain classes

To write our components and keep css grouped we chain classes like this :

    .user {
      /* CSS Awesomeness */
    }    

    .user .-profile {
      /* CSS Awesomeness */
    }    

    .user .-profile .-avatar{
      /* CSS Awesomeness */
    }
