Fluid Styled Content

Fluid Styled Content is a core extension of TYPO3 which provides all the regular content elements you can find in your installation like Header, Text and Text & Images. Mask does not depend on it directly, but it is good practice to include it nevertheless. Most of the time you will want to have some generic content elements for your site. Even if you don't need them, this extension includes the TypoScript snippet lib.parseFunc_RTE too, which is essential for TYPO3 richtext parsing. Also you can use the standard layout of Fluid Styled Content by specifying the paths in TypoScript.
