Django template tags to compile LESS into CSS

Django LESS provides template tags to compile LESS into CSS from templates. It works with both inline code and extenal files.

Installation

1. Add "less" to INSTALLED_APPS setting.

2. Make sure that you have lessc executable installed. See LESS official site for details.

3. Optionally, you can specify the full path to lessc executable with LESS_EXECUTABLE setting. By default it’s set to lessc.

Example Usage

Inline

{% load less %}

<style>
  {% inlineless %}
    #header {
      h1 {
        font-size: 26px;
        font-weight: bold;
      }
      p { font-size: 12px;
        a { text-decoration: none;
          &:hover { border-width: 1px }
        }
      }
    }
  {% endless %}
</style>

renders to

<style>
  #header h1 {
    font-size: 26px;
    font-weight: bold;
  }
  #header p {
    font-size: 12px;
  }
  #header p a {
    text-decoration: none;
  }
  #header p a:hover {
    border-width: 1px;
  }
</style>

External file

{% load less %}

<link rel="stylesheet" href="{{ STATIC_URL}}{% less "path/to/styles.less" %}" />

renders to

<link rel="stylesheet" href="/media/LESS_CACHE/path/to/styles-91ce1f66f583.css" />

Note that by default compiled files are saved into LESS_CACHE folder under your STATIC_ROOT (or MEDIA_ROOT if you have no STATIC_ROOT in your settings). You can change this folder with LESS_ROOT and LESS_OUTPUT_DIR settings.

Note that all relative URLs in your stylesheet are converted to absolute URLs using your STATIC_URL setting.

Settings

LESS_ROOT
