Fluid

Sitepackage

In TYPO3, (almost) everything is an extension. If you want to create a theme, override some configuration or add custom content elements you will do this in a custom TYPO3 extension. A sitepackage is an extension that contains the foundation (in particular, the visual appearance) of a website: The configuration, necessary assets for a theme (images, css etc.) and a combination of TypoScript and Fluid.

You can use Fluid in TYPO3 to do one of the following:

• Create a template (theme) using a combination of TypoScript FLUIDTEMPLATE and Fluid. Check out the TYPO3 Sitepackage Tutorial which walks you through the creation of a sitepackage extension.

• Create a custom content element type in addition to the already existing content elements TYPO3 supplies.

• The previous point describes the lightweight components which are created using a combination of TypoScript and Fluid. If you need more functionality or flexibility in your content element, you can create a content plugin using a combination of Extbase and Fluid. This is explained in t3extbasebook:Index

• Use Fluid to create emails using the TYPO3 Mail API.

• Use Fluid in backend modules.
