BEM methodology is not about CSS - eviltoast
Some developers are sure that BEM is just a way to make class names in CSS are unique and, since a modern tools allow to make names unique automatically they have no reasons to use BEM. This is a mistake with a bad consequences, BEM is are methodology about atomic code design, it gives you a standards and guides how to simplify code maintaining.

Some frontend developers know the BEM methodology as a naming convention for CSS and they create a disgusting #webcomponents. I’ve explain the essence of BEM and shown the benefits for your frontend projects.

Feel free to share it with a people who tells you “i use CSS-modules, so i no needs a BEM”
