This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



This plugin helps you to build and maintain your website with LESS. LESS is a dynamic stylesheet language.

This plugin is build with: LESS.php


  • No extra checks (server time) to load your lastest CSS
  • LESS editor for small changes or child themes

Examples and usages

wpless2css/wpless2css.less will be your master LESS file. Add your LESS code here or import other LESS files.

All LESS files should be place in wpless2css/ for now.

wpless2css/wpless2css.less could contain simple or more complex LESS code like:


Or more complex intergrate Twitter’s Bootstrap’s CSS:

  • Download the latest version from:
  • Copy all *.less to wpless2css/
  • edit wpless2css/wpless2css.less

    @import “bootstrap.less”;

Load Glypchicons:

  • Copy all /fonts/ to your web server
  • edit wpless2css/wpless2css.less

    @import “bootstrap.less”;
    @icon-font-path: /fonts/;

**Note:*: Go to the settings and save settings after changing you LESS code to create a new CSS file.

Theme developers

Call wp-less-to-css.php from your functions.php to bundle the plugin:

require dirname(__FILE__) . '/vendor/wp-less-to-css/wp-less-to-css.php';

Save the CSS (conditional) automatic by adding to your function.php:

$updatecss = WP_LESS_to_CSS::$instance;

Only save the CSS on changes. Compile a new CSS every time your page loads will make your site slow, but you can use it for testing.

Use the save action after changes via the customizer for example:

add_action( 'customize_save_after', 'lesscustomize' );

function lesscustomize($setting)
//$setting is no used here, see also:
$updatecss = WP_LESS_to_CSS::$instance;
add_filter( 'add_extra_less_code', 'add_extra_less_now_live');
function add_extra_less_now_live($parser)
    return 'a{color:'.get_theme_mod( 'heading_color').'} p{color:orange;}';          

Depending on your needs wpless2css/wpless2css.less can be moved from root to the theme or child theme directory (wp-content/themes/{yourtheme}/wpless2css/wpless2css.less).
