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”
Have you worked with Bootstrap at all?
Very little (and long ago). We usually use a frontend stack of Angular and PrimeNG for our projects.
