Another ‘style’ we need to concern ourselves with is our grammar, spelling and usage style. For example, is ‘drop-down’ or ‘drop down’ correct? (Depends… if used as a noun or adjective, like ‘drop-down menu’ then the hyphen is correct. If used as a verb, as in “drop down and give me ten”, then no hyphen.) A style guide is a set of standards for the writing of documents that ensures consistency throughout a document, and encourages proper usage of the language.
