+To separate EE-specific styles in SCSS files, If a component you're adding styles for,

-### Isolating EE-specific ruleset within SCSS file

-There are situations where creating dedicated SCSS file is an overkill, for eg; a text style
-of some component is different for EE. In such cases, styles are usually kept in stylesheet
-that is common for both CE and EE, and it is wise to isolate such ruleset from rest of
-CE rules (along with adding comment describing the same) to avoid conflicts during CE to EE merge.
