This document discusses various codes and conventions used on magazine double page spreads, including drop caps, pull quotes, stand firsts, columns, main images, backgrounds, fonts, headlines, captions, banners, bi lines, text layout, and mise en scene. It explains that drop caps are large capital letters that draw attention at the start of an article. Pull quotes make snippets of text from the article larger to stand out.
