Title: WP-LESS Author: thom4 Published: 14 août 2009 Last modified: 14 mai 2025 --- Recherche d’extensions Cette extension **n’a pas été testée avec plus de trois mises à jour majeures de WordPress**. Elle peut ne plus être maintenue ou supportée et peut avoir des problèmes de compatibilité lorsqu’elle est utilisée avec des versions de WordPress plus récentes. ![](https://s.w.org/plugins/geopattern-icon/wp-less.svg) # WP-LESS Par [thom4](https://profiles.wordpress.org/oncletom/) [Télécharger](https://downloads.wordpress.org/plugin/wp-less.1.9.8.zip) * [Détails](https://fr.wordpress.org/plugins/wp-less/#description) * [Avis](https://fr.wordpress.org/plugins/wp-less/#reviews) * [Installation](https://fr.wordpress.org/plugins/wp-less/#installation) * [Développement](https://fr.wordpress.org/plugins/wp-less/#developers) [Support](https://wordpress.org/support/plugin/wp-less/) ## Description [LESS](http://lesscss.org) is a templating language based on top of CSS. It provides numerous enhancements to speed up development and make its maintenance easier. Theme developers can even bundle the plugin without worrying about conflicts: just include the special `bootstrap-for-theme.php` and read its instructions. #### Fonctionnalités * Variables * Mixins (inheritance of rules) * Nested Rules (write less, do more) * Accessors (inherit a value from a specific rule) * Functions (logic operations for dynamic results) The plugin lets you concentrate on what you need: coding CSS. Everything else is handled automatically, from cache management to user delivery. Seriously. #### Documentation Advanced topics on how to use the plugin API are [available on the Github project documentation](https://github.com/oncletom/wp-less/tree/master/doc). #### Pré-requis The sole requirement is to use WordPress API and LESS convention: the `.less` extension. **Minimal Requirements**: PHP 5.3 and WordPress 3.2. **Relies on**: [Less.php](http://lessphp.gpeasy.com/), [plugin-toolkit](https://wordpress.org/extend/plugins/plugin-toolkit/). _Notice_: in case you’d like to drop the usage of this plugin, it’s safe to do it. You will just need to convert back your stylesheets to CSS. ## Captures d’écrans * [[ * Sample of LESS to CSS conversion. ## Installation #### Automatic 1. Search for the plugin name (`WP-LESS`) 2. Click on the install button 3. Activate it #### Manuel 1. Download the latest stable archive of the plugin 2. Unzip it in your plugin folder (by default, `wp-content/plugins`) 3. Activate it through your WordPress plugins administration page ## FAQ Lots of efforts have been done to write a [consistent documentation](https://github.com/oncletom/wp-less/tree/master/doc) to address issues you may encounter. It covers topics like path customization, declaring LESS variables from PHP, creating new LESS functions etc. ## Avis ![](https://secure.gravatar.com/avatar/4421020034e4cc91742bf6fab4237e291698da45417c13e9e67b697d64e1a1b9? s=60&d=retro&r=g) ### 󠀁[Very good](https://wordpress.org/support/topic/very-good-1825/)󠁿 [marcrock](https://profiles.wordpress.org/marcrock/) 15 janvier 2017 Nice to work with it.

It allows to easly add Less support to your WP theme. No needed configuration, just treat your *.less files like regular *.css in your theme’s directory. ![](https://secure.gravatar.com/avatar/8cd09c0df68d58750e849438cb5268d1751c2e70592e72f5fb32b9700b1ab039? s=60&d=retro&r=g) ### 󠀁[Saves time for those Less experts](https://wordpress.org/support/topic/saves-time-for-those-less-experts/)󠁿 [alvinkonda](https://profiles.wordpress.org/alvinkonda/) 3 septembre 2016 Thank you for this amazing plugin, it saves us Theme Developers lots of time with this simple implementation directly from the theme. i love the passing of variables as well. The only thing im not yet figuring it out is the CSS generated from the plugin doent cache, am i missing sth? ![](https://secure.gravatar.com/avatar/c3919b8792d375e1011cbadd5c963cb1827671a22a3c54df477df20805eb4192? s=60&d=retro&r=g) ### 󠀁[Works perfectly](https://wordpress.org/support/topic/works-perfectly-761/)󠁿 [Marie-Aude](https://profiles.wordpress.org/marie-aude/) 3 septembre 2016 A wonderful tool to get rid of headers bloated with css.
