ABEM. A more useful adaptation of BEM.

BEM (Block Element Modifier) is a popular CSS class naming convention that makes CSS easier to maintain. This article assumes that you are already familiar with the naming convention. If not you can learn more about it at getbem.com to catch up on the basics.

The standard syntax for BEM is:

block-name__element-name--modifier-name

I'm personally a massive fan of the methodology behind the naming convention. Separating your styles into small components is far easier to maintain than having a sea of high specificity spread all throughout your stylesheet. However, there are a few problems I have with the syntax that can cause issues in production as well as cause confusion for developers. I prefer to use a slightly tweaked version of the syntax instead. I call it ABEM (Atomic Block Element Modifier):

[a/m/o]-blockName__elementName -modifierName
