Normally a template reference has a path specified. Partials are different. Hugo searches for them along a TODO defined search path. This makes it easier for end-users to override the theme's presentation. +In Hugo, a partial is a template that's intended to be used within other templates. We're going to use partials to create a single header template that other templates will use. That gives us one place to maintain the header information, which makes maintenance much easier. So much easier, in fact, that we'll jump in and do the same for the footer, too. -``` +```bash $ vi themes/zafta/layouts/partials/header.html - {{ .Title }} + {{ .Title }} :wq @@ -1031,32 +1099,35 @@ $ vi themes/zafta/layouts/partials/footer.html The most noticeable difference between a template call and a partials call is the lack of path: -``` +```bash {{ template "theme/partials/header.html" . }} ``` + versus -``` + +```bash {{ partial "header.html" . }} ``` -Both pass in the context. -Let's change the home page template to use these new partials. +Both pass in the context (that's the period just before the closing moustache). -``` +Let's change the home page template to use these new partials we just created. + +```bash $ vi themes/zafta/layouts/index.html {{ partial "header.html" . }} -
