Color Section Shifted below Footer

See below

Removing all the Quick CSS and deactivating plugins does not affect it.
I did remove the functions.php child theme though and it corrected it.
The problem appears to be in this block of code which was suggested to me by Ismael in order to get the post titles to appears on the thumbnails on the homepage sliders.
// slide link
add_action(‘wp_footer’, ‘ava_new_custom_script’);
function ava_new_custom_script(){
?>
<script type=”text/javascript”>
(function($) {
function b() {
$(‘.slide-entry’).each(function() {
var content = $(this).find(‘.slide-content’).detach();
$(this).find(‘.slide-image’).append(content);
});
}

b();

$(‘#av_section_2’).appendTo(‘#main’);
})(jQuery);

</script>
<?php
}

Can you tell me what the conflict might be?

Thanks Ismael.
That entire code block was given to me by you in this thread: https://kriesi.at/support/topic/move-post-slider-text-content-into-thumbnail/

Removing it seems to do the trick and the issue that the other thread was addressing does not seem effected.
So both seem to be solved.
If you want to share what the thoguth was behind that bit of code, I am always happy to learn.
Thanks again.
