Extensible Stylesheet Language Transformations (XSLT) is an XML-based language used, in conjunction with specialized processing software, for the transformation of XML documents. Although the process is referred to as "transformation," the original document is not changed; rather, a new XML document is created based on the content of an existing document. Then, the new document may be serialized (output) by the processor in standard XML syntax or in another format, such as HTML or plain text. XSLT is most often used to convert data between different XML schemas or to convert XML data into web pages or PDF documents. [one]
XSLT allows a stylesheet author to transform a primary XML document in two significant ways: manipulating and sorting the content, including a wholesale reordering of it if so desired, and transforming the content into a different format.

Why does MDN look different?
MDN is changing to focus just on documenting web technologies. All the same great content is still here; we’re just changing some visual elements and navigation, to help you more quickly find the web technology docs you’re looking for.
But don’t worry, MDN and Mozilla are still together! In fact, we're updating MDN’s look to reflect Mozilla's new logo and colors.
