{{Navbar}} provides a small "view · talk · edit" navigation bar. It is primarily used for content-heavy templates and other transcluded content blocks, so that the content inside the template or block is more easily editable in situ where it was found, without having track it down through examining transclusion code. {{Navbar}}'s extremely high use rate and consequent protection level are because it is integrated as a feature into numerous navigation box and infobox templates used in millions of articles. It is also a regular feature of many internal-use templates and tables of the Wikipedia, Help, and Template namespaces.
When one of the following examples is placed inside a given template (or block of content used for selective transclusion), it adds basic navbar navigational functionality:
When used in content that is selectively transcluded but which is also used as-is in its original location, this template should be wrapped in <includeonly>...</includeonly> markup, so that it only appears when transcluded.
Font-size is 88% when used in a topical navbar template or in plain text, and 100% when nested in a navbox or infobox (because those templates' text size is already reduced; the "100%" is relative to the surrounding template's own content, not that of the entire page). The |fontstyle= parameter can be used to adjust font size as needed (e.g. to reduce font size even more when the template is used inside a block element with a large font size). Do not abuse this to make excessively small text (i.e. less than 85% of the normal page text), since that causes accessibility problems for many readers.
In a topical navbar, the weight is "normal"; when nested in a navbox or infobox, it inherits the style of the surrounding content. The middot bullets are bold for better visibility.
The template generates block-level markup with <div>...</div> tags, and therefore, any surrounding markup cannot include <span>...</span> tags, which would cause a div-span-flip lint error.
