Module Chrome Module chrome is a term for PHP functions that provide some optional HTML markup in which the module code is placed. This is often called a wrapper for the module output. Module chrome allows template designers to have a certain amount of control over the way the output from a Module is displayed in their template. Essentially, it consists of a small amount of predefined HTML which is inserted before, after, or around the output from each module, and which can then be styled using CSS. Module chrome is commonly used to provide borders around modules, especially with rounded corners, but it can be used for much more than that. Module chrome is determined by using the 'style' attribute in the statement calling the module. For example, the following statement may be used in the index.php file of a template to insert the Modules in the 'user1' position and apply the 'custom' Module chrome: <jdoc:include type="modules" name="user1" style="custom" /> It can be seen that the same Module chrome is applied to every Module in that position - in other words, if you want to have two Modules in a column, but want them to have different Module chrome, then they would need to be set up as two different 'positions' (e.g. 'user1' and 'user2'). The standard Joomla! 1.5+ package includes six default Module chrome styles. However, the flexibility of the template system means that you are not limited to these styles - it's very easy to create as many new styles as you want! Reference: http://docs.joomla.org/Glossary
Language Languages are perhaps the most basic and critical extension type. Languages are packaged as either a core language pack or an extension language pack. These packages consist of INI files which contain key/value pairs. These key/value pairs provide the translation of static text strings within Joomla! source code. This allows both the Joomla! core and third party components and modules to be internationalised. Core language packs also include an XML meta file describing the language and providing information about the fonts to use for PDF content generation. Reference: http://docs.joomla.org/Glossary
