  <p>I want to deregister this style <strong>gforms_datepicker_css</strong> in functions.php using my codes below but it does not works.</p>
  
  <pre><code>add_action( 'wp_print_styles', 'my_deregister_styles', 100 );  
  function my_deregister_styles() {
      if( is_front_page() || is_home() || is_page( 403 ) ){ 
          wp_deregister_style( 'gforms_datepicker_css' );
      } 
  }
  </code></pre>
