Block Classes allows users to add classes to block title, content, and wrapper of any block through the block's configuration interface. This module extends the Block Class module features.
In some cases, we have to write twig file for blocks, if we want to add separate classes for block wrapper, title, and its content. Instead of writing twig's, we can handle it using the Block Classes module.
