Ranked in these QuestionsQuestion Ranking
Pro Fast to read and write CSS
Works like Emmet, shorting CSS keywords, but it's not limited only to writing. Also modifying and reading COD(CSS-On-Diet) files is faster.
Pro Easy to learn and use
Doesn't require programming skill to work with variables, mixins, media breakpoints
Con It's difficult adjusting to different keywords
The keywords are shortened to 3 letters. For example, "background-color" becomes "bac" and "max-width" becomes "maw". These keywords are far less intuitive than their original form and make the CSS much less readable for those who don't know CSS-On-Diet.
Con Extremely limited adoption
CSS-On-Diet has just 7 stars on Github and a very small adoption rate. For an open source project this usually means less bugs reported, lesser documentation and few third-party learning resources.
