What is position XSLT?

The position() function gives you the position of the current node within the “current node list”, which is whatever was select -ed by the nearest apply-templates or for-each (XSLT 2.0 refers to “items” and “sequences” rather than nodes and node lists but the principle is the same).

How is XSL different from CSS?
