Is possible dequeue/remove style from wp_footer() hook and add on wp_head() hook?

by

If you look at the source code, you can see that wp_enqueue_style( 'crayon' ) is called in Crayon::enqueue_resources() which itself is called either from either Crayon::the_content() or Crayon::wp_head(). The code in Crayon::wp_head is:

if (!CrayonGlobalSettings::val(CrayonSettings::EFFICIENT_ENQUEUE) || CrayonGlobalSettings::val(CrayonSettings::TAG_EDITOR_FRONT)) {
  CrayonLog::debug('head: force enqueue');
  // Efficient enqueuing disabled, always load despite enqueuing or not in the_post
  self::enqueue_resources();
}

Which will enqueue the style only when certain settings are enabled. Otherwise, the style will only be enqueued from the_content filter which fires after wp_head has already been output.

So your two options are:

  1. Have the CSS enqueued on all pages in the header
  2. Have the CSS enqueued only on necessary pages but in the footer
