I am making a promo for submissions of recipes. I am making a list; checking it twice. A fellow grammar n_ tells me that the corporate style guide says colons before lists, and it is true. That is what I did until this same person asked me to bold the texts before the lists, essentially making them subheadings in my opinion. Now, because of that, I decided to drop the colons. Am I wrong? Should I have kept them lest I incur wrath?
I neglected to mention it had to do with bulleted/numbered lists… When I was given the suggestion to bold What to include, I dropped the colon because to me it becomes a subheading, making the colon redundant.
This depends on if you want a full stop after the content that proceeds your list (this would be the bold header style) or of the list is intended to be part of some proceeding paragraph or content (then you want the colon).
The most important thing is that you’re consistent throughout
You can consult whatever grammar-Godwins you can find here, or check style guides that are considered authoritative, for example https://www.chicagomanualofstyle.org/ . Of course, YMMV. The great thing about standards is that there are so many to choose from.
Style debates are of small moment, but in quantity can deliver death by a thousand cuts. If there is a corporate guide, consult it and instruct all nit pickers to do the same. If there isn’t, choose one and throw that at the nit pickers. The goal is to keep nit pickers at bay, for otherwise they’ll eat you alive with their endless twaddle.
