A wrapper for less.php to integrate LESS into SilverStripe.


  • Integrates a fork of less.php seemessly into SilverStripe
  • Includes flushing option (?flush) to regenerate CSS stylesheets (ie. force undetected less changes with @import)
  • Writes processed *.css files into assets/_css and automatically modifies Requirements paths
  • Allows custom global variables to be passed through to less compiling (yaml configuration)
  • Automatic image & @import URL translation (eg: url('../image.png') will get rewritten as url('/path/to/image.png') depending on your website's root folder)
  • Automatic compression of CSS files when in Live mode (may require an initial ?flush)
  • Adds any processed editor.less files to TinyMCE (must be included in your front-end template)


  • SilverStripe 4

For SilverStripe 3, please refer to the SilverStripe3 branch.


composer require axllent/silverstripe-less


You need refer to your less files by their full LESS filenames (eg:stylesheet.less).


use SilverStripe\CMS\Controllers\ContentController;
use SilverStripe\View\Requirements;

class PageController extends ContentController
    public function init()

The generated HTML will point automatically to the processed CSS file in assets/_css rather than the original less file location, for example

<link rel="stylesheet" type="text/css"  href="/assets/_css/themes-site-css-stylesheet.css?m=123456789" />
