Interface chrome
Also called chrome, UI chrome.
In plain English
Interface chrome is the frame around the content: navigation, toolbars, and other controls that are not the content itself.
Example
You hide the site header to read a long article. The article is the content. The header you hid is chrome.
Why it matters
A header, a sidebar, and a toolbar are chrome. The article or the main work area is the content. The same English word is also the name of Google's Chrome browser. This page is about the interface frame, not that browser.
Common confusion
Interface chrome is not Google Chrome. If a sentence is about the browser, it is not this term.
