Internal links
The easiest way to link to pages and assets is to use relative paths. These will work in both development and production, and should be very predictable based on the names of your directories and files.
For example:
<!-- (HTML) -->
<!-- To link to <repo>/content/pricing/enterprise.html -->
<a href="/pricing/enterprise/">Pricing</a>
The same is true for images, CSS, etc.
In some cases, like open graph tags, you are required to use an absolute URL which gets more complicated.
