CSS Sass convention

Naming class css like this : component__element-part--modifier

the component is tracked by 2 _
If you want to work on a part of this element, the part is preceded by 1 -
If you need to modify your part or your element, you use 2 -- before your modifier
If the name component has too much parts in its name, you can minify it using the first letters.

You can do that only on the component.
- example : form-search-engine__form-group__label--large
  - the component form-search-engine can be minify to have :
    
    fse__form-group__label--large
When you do that, you have to put a comment just above your class in the css to explain the minification : // form-search-engine

To comment Sass code you can use two methods :

Prefer the second one : //
