Asset management plugin for Pelican
|
|
===================================
|
|
|
|
This plugin allows you to use the `webassets`_ module to manage assets such as
|
|
CSS and JS files.
|
|
|
|
The ASSET_URL is set to a relative url to honor Pelican's RELATIVE_URLS
|
|
setting. This requires the use of SITEURL in the templates::
|
|
|
|
<link rel="stylesheet" href="{{ SITEURL }}/{{ ASSET_URL }}">
|
|
|
|
.. _webassets: https://webassets.readthedocs.org/
|
