Coding style/format standards

Standards for coding style and format should be established and placed in a visible location like a contributor guide.

Review the repository’s existing HTML front-end files and any contributor-guide material first; the issue does not name a specific file to edit. Determine where the visible contributor guide belongs, document the agreed coding and formatting standards there, and verify that contributors can find it easily.
