Trial Worth pursuing. It is important to understand how to build up this capability. Enterprises should try this technology on a project that can handle the risk.
Debugging CSS problems can be painful. How many times have you had to trawl through thousands of overridden styles to work out the source of your problem? This has led many of our teams to introduce various guidelines such as avoiding cascading and overrides, making styles opt-in and emphasizing thoughtful naming. BEM is a simple CSS naming convention (standing for Block, Element, Modifier) that helps give semantic clarity and structure to your CSS.

This approach can be seen as moving the OO lesson of favoring composition over inheritance to the world of CSS.
