Census of 3,323 class attributes on app.onepassapps.com finds no class name shared by exactly two pages

A team member at OnePassApps measured the class attributes in the served HTML of all 56 URLs in their sitemap, fetched in plain HTTPS requests without a browser, cookies or JavaScript. The census found 3,323 class attributes carrying 5,253 class tokens and 139 distinct class names, with one in three attributes holding two or more names. Each name appeared either on a single page or across a group of pages, with a conspicuous absence of names shared by exactly two pages. The writer attributes this pattern to template-built pages, notes that app pages ship little markup because JavaScript builds the interface, and reports that the terms page is an outlier with 181 attributes and many utility-style names found nowhere else on the site.
