Say I have a template layout saved in template.html. This template includes a banner, side navigation, content container, and footer. Can I use flask to break up these page elements in such a way that I can have files such as banner.html, sidenavigation.html, etc. and render these different files within template.html?
From: http://jinja.pocoo.org/docs/templates/#include
template.html
{% include 'banner.html' %}
{% include 'sidenavigation.html' %}
{% include 'content.html' %}
{% include 'footer.html' %}

By default, Flask uses Jinja2 as its template engine. See Jinja's Template Designer Documentation how it's done.
