Global layer on Layer slider

It calls “Static layer”, found solution here: https://kriesi.at/support/topic/layerslider-wp-static-slide-layer-over-all-slides/

But is any way to add code inside layer slider div?

But if slide change – this layer fade-out and fade-in again or blink.

The best way to make this is a function:

add_filter('ava_after_main_container', 'ava_after_main_container_mod', 20, 1);
function ava_after_main_container_mod() {
$output = 'custom_code';
echo $output;
}

Solved.
