adding css to single page


I have created a single dashboard page, I want to add css to it but have tried
$this->addHeaderItem($html->css('mystyle.css', 'css')); in both the view and the page.

How can I add (in the header) a css file?
Where should I put the css file?
If the error "Call to a member function css() on a non-object" happening because it cannot find the css file or because the method call is illegal?

I do not want to edit core themes header but add the css later.

You need to create a controller for your single page, and ideally put addHeaderItem for the css within an On Start event handler function.
