Punctuation

Q. Good day! I am currently revising our stylebook based on The Chicago Manual of Style. I would like to ask if you have a strict standard on slashes, whether I should put a space after the slash before typing/writing the next element, or is it all right if there is none?

A. If the slash divides two words, there is no space. If it divides two phrases or sentences (or a single word from a phrase), it requires a space before and after. Please see CMOS 6.106.
