CSS injection: Extract CSRF-token by using inline-css injection

Is it possible to extract CSRF-token by using inline-CSS injection (inside style attribute)? (It seems to be impossible, because it is not possible to define CSS classes inside attributes.)

<p style=<?php echo htmlspecialchars($  _GET["css-injection-here"]); ?>>wubwub</p> 

It seems that internet knows only about stealing CSRF-tokens with CSS-injection which happens inside <style> tags:

<style> <?php echo htmlspecialchars($  _GET["css-injection-here"]); ?> </style>
