Ein sehr gutes Plugin – schon auch in der Freien Version ist WP Armour
Dort im Link oben kannst Du auch schon nachlesen, wo das Plugin sich automatisch einbindet. Enfold ist in der Liste nicht aufgeführt, aber auch Enfold Kontaktformulare werden unterstützt.
Ich bin mir nicht sicher, ob das nur bei meiner Pro Version so ist, aber die “Enable 2 Level Spam Check” sollte man nicht aktivieren. Hier hatte ich zuviele false positiv Resultate.
Such mal nach Erfahrungen mit dem Plugin – danach wirst du dein f12 Captcha ausmisten.

show me please the page – or post for the mods in private content – ps read my post that i set in the time you posted yours.

if you are having this a lot and only on copyright, tradmark etc. you can do this in one short snippet for child-theme functions.php:
just place that character and let the script do the sup-wrapper

function wrap_copyright_text_with_sup(){
?>
<script>
(function($) {
$(document).ready(function() {       
     $('body :not(script)').contents().filter(function() {
        return this.nodeType === 3;
        }).replaceWith(function() {
            return this.nodeValue.replace(/[™®©]/g, '<sup>$&</sup>');
     });
});
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'wrap_copyright_text_with_sup');

if you like to have manual control just place vor Menu Items in Navigation Label : <sup>ABC</sup>
or to have it sub similar to it H<sub>2</sub>O
edit menu-item ( red circle ):

maybe this is a possible way to reach the same only with enfold alb usage:

On newer Enfold we got the options to position that 1/1 container absolutely – and if we place it absolute: 0 ( set to a higher z-index )
We have then no background-images but a real slider with real cross-fade options because we got images.
The only problem is responsive behavior : In the end, the image of the slider determines the height of the cell. If this content gets higher then the images – it will “overflow” this “background-slider”. This absolute positioning you can set only for wider screens – and on mobile you can have the normal behavior etc. pp.

see example: https://webers-testseite.de/test-temp/

i got this function – and it is a bit different from Yigits – but it is nearly the same background on how to achive this.

But now my question – this looks only good after the first cycle – till the images are in the browser cache.
Is it possible to have a preloading of the image array on page loading?

function av_grid_slide(){
?>
<script>
window.addEventListener("DOMContentLoaded", function () { 
    (function($){  

        var cellSlider = $('.grid-slider');
        var images = [
                  'url(/wp-content/uploads/test-london.jpg)', 
                  'url(/wp-content/uploads/test-paris.jpg)',
                  'url(/wp-content/uploads/test-newyork.jpg)',
        ];

        $(function () {
            var i = 0;
            cellSlider.css("background-image", images[i] );
            setInterval(function () {
                i++;
                if (i == images.length) {
                    i = 0;
                }
                cellSlider.fadeOut("1000", function () {
                    $(this).css("background-image", images[i] );
                    $(this).fadeIn("1000");
                });
            }, 5000);
        });

    })(jQuery);
 });
</script>
<?php
}
add_action('wp_footer', 'av_grid_slide'); 

btw: that double Quotation is in Yigits Code above

these are page-content inserted via the page-content alb to your page? or how do you inserted this content?

_______
btw: think of the former tip for those fixed images – and mobile support. This does not work on parallax – so if there is the custom-class : bg-fixed set before – because it was a former fixed bg style.

@media only screen and (max-width: 767px){
  .responsive #top .avia-post-nav {
    display: block;
  }
}

but i guess on next enfold version there will be a swipe support on post-navigation.

i don’t know where you need this rule – but you had to be more spezific for the elements you like to influence.

.archive.author header.entry-content-header {
  margin-bottom: -50px;
}

this is causing it – remove that rule and:

#top .template-author .content .post .entry-content-wrapper {
  padding-bottom: 0px;
}

and because you do not show meta content here
and if you do not like to have that separation

#top .template-author .content .post-meta-infos,
#top .template-author .content .author-extra-border {
  display: none;
}

#top .template-author  .page-heading-container {
  border-bottom: none !important
}

if you like to style it – and have it a bit larger:

#top .post-author-format-type .rounded-container {
    width: 100px;
    height: 100px;
    border-radius: 25%
}

#top .post-author-format-type .rounded-container img {
  width: 100%;
  border-radius: 25%
}

Hast du mal den Link zu deiner Seite ?

zunächst ist ja auch das “bring to front” im svg divider – wenn das aktiviert ist, bekommt das svg bzw. der wrapper einen z-index von 100.
mach diesen haken mal raus.

PS gut das im Screenshot dein Tel gut zu sehen war ;) die Seite zu inspizieren ist nämlich leichter als Vermutungen anzustellen.

the SVG separators are not tricky and you even have a nice preview of what the settings will do.

click to see full resolution:

Is there a page where normal users can also look at the matter?

If there is a section that is above the section where you want the divider, you can set up a bottom divider for that section.
Another option would be to give the color section a custom class, and all of these will have the top divider mirrored up.
See here – my snippet for a divider between a slider and the next color section. Since the slider doesn’t have this option, we need this trick here.
https://webers-testseite.de/divider-on-sliders/

you are concerning to the svg dividers ? or have you done it with the slant option? – i would always prefer the svg dividers.

i can not see how you have set the gradient for the first button – it is not via quick css – it shows it is an inline style – so you have to look where this rule is:

.avia-cookie-consent-button-1{
	/* Permalink - use to edit and share this gradient: https://colorzilla.com/gradient-editor/#8fc800+0,63aa00+100 */
background: #8fc800 !important; /* Old browsers */
background: -moz-linear-gradient(45deg,  #8fc800 0%, #63aa00 100%) !important; /* FF3.6-15 */
background: -webkit-linear-gradient(45deg,  #8fc800 0%,#63aa00 100%) !important; /* Chrome10-25,Safari5.1-6 */
background: linear-gradient(45deg,  #8fc800 0%,#63aa00 100%) !important; /* W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#8fc800', endColorstr='#63aa00',GradientType=1 ); /* IE6-9 fallback on horizontal gradient */
border: none !important;
	color: #ffffff !important;
}

delete the rule for the button-2 and add the selectors for the other button to that rule above:

.avia-cookie-consent-button-1,
.avia-cookie-consent-button-2,
.avia-cookie-consent-button-3 {
	/* Permalink - use to edit and share this gradient: https://colorzilla.com/gradient-editor/#8fc800+0,63aa00+100 */
background: #8fc800 !important; /* Old browsers */
background: -moz-linear-gradient(45deg,  #8fc800 0%, #63aa00 100%) !important; /* FF3.6-15 */
background: -webkit-linear-gradient(45deg,  #8fc800 0%,#63aa00 100%) !important; /* Chrome10-25,Safari5.1-6 */
background: linear-gradient(45deg,  #8fc800 0%,#63aa00 100%) !important; /* W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#8fc800', endColorstr='#63aa00',GradientType=1 ); /* IE6-9 fallback on horizontal gradient */
border: none !important;
	color: #ffffff !important;
}

Was ich mir vorstellen könnte, ist das du die Besucher deiner Seite bittest aktiv ihre Herkunft offen zu legen; indem du das entsprechende Bundesland abfragst.
Ich denke aber es wird wahrscheinlich leichter sein, die Telefonanlage dementsprechend zu programmieren, das eine auf deiner Seite angegebene Zentrale Nummer – je nach Vorwahl des Anrufers zu der entsprechenden Stelle weitergeleitet wird. Hier ist eine Herkunft leichte zu bestimmen.

Es über die Besucher IP ( Geolocation IP etc. pp ) zu machen ist höchst wahrscheinlich nicht DSGVO konform.
