Docs coming soon ... in the meantime file an issue if you have any question

The idea of all class names (well more and less) are picking the first letter of each word of css proprty, e.g background-size, and css value, e.g cover separated by dash, for example:

• background-size: cover becomes bs-c
• background-image: none becomes bi-n

Of course there are some exceptions, for example we have background-size: cover and background-size: contain, based on above guideline the class name for both will be bs-c which is not acceptable, so I apply the above guideline to background-size: cover, because it's more common, and use the full value name for less common one, so background-size: contain becomes bs-contain. there are some other exceptions which will be covered in the documentation.
