Double page spreads in documents typically have large, eye-catching headers to introduce the topic. The main body text is structured and organized in a rigid format like lines, rules or grids to give the appearance of an important article for readers. Pictures used are usually portrait style to make them easier for viewers to observe closely while reading the more effortful text, helping keep readers engaged. Pull quotes are also used to succinctly summarize the whole piece and highlight key lessons for the audience.
