Hugo uses Go's text/template and html/template packages.

The text/template package implements data-driven templates for generating textual output, while the html/template package implements data-driven templates for generating HTML output safe against code injection.

By default, Hugo uses the html/template package when rendering HTML files.

To generate HTML output that is safe against code injection, the html/template package escapes strings in certain contexts.
