A validation error php/html

[990805]

hello,

 

Iam workin with Joomla and i inserted a module. i checked my page with w3c validation and getting some errors.

 

One of them is

 

document type does not allow element "style" here

Where do i have to put this. It says i have to put it in the body tag, but where can i do that because this code:  <style type="text/css"> is in a php file..

 

thanks
