YAML ( Yet Another Multicolumn Layout ) is a cross-browser CSS framework . It allows web designers to create a low-barrier website with comparatively little effort. Integrations of the YAML layouts have been created for various content management systems. These include WordPress , LifeType , TYPO3 , Joomla , xt: Commerce and Drupal .

As of YAML version 2.2, the framework is distributed under the Creative Commons Attribution 2.0 License (CC-BY 2.0). As an alternative for the use of the framework, there are two paid subscription models.
