Publishing styles are Publishing Project documents that are stored in the System/Publishing/Styles folder in the Library. Within the Styles folder, each category has a folder. Each output format has its own Project document, such as Job Aid and Player.
You can use categories to create customized styles to change the branding, that is, the logo, or format the appearance of the published output. You can also create categories with only certain published outputs, such as Job Aid and Training Guide, to limit the publishing outputs available to the content authors.
Note: If you create custom publishing styles, you should document your customizations so you can easily re-apply them, if necessary, after a software upgrade.
