The XML declaration…

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

…, if included, must be the very first thing in the document. You have it appearing after a style element.

That said, version 1.0 is the default, UTF-8 is the default, and no is the default. So you can leave it out entirely.

What's more, assuming you are writing XHTML and serving it as text/html, you should leave it out entirely, as per the first of the compatibility guidelines.

where should i be pasting the style?

A style element can only appear in an XHTML 1.0 document as a child element of the head element.
