nicht dafür ! ;)

and even here there is the colon missing after margin -and the units of the value ( zero could be without unit ) !

<p style="text-align: left; margin: -10px 0 0 0;"><img class="alignnone size-full wp-image-111" src="https://hr-pflege.de/wp-content/uploads/2021/09/1.png" width="20" height="20"/></p>

no – definitly not only the closing tag
that was a completely wrong way to write down the css. I would be very surprised if it would work anywhere.
on margin – no separators between the values !
if you have 4 values on it it is: margin: 10px 0 0 0 ;
( means margin-top: 10px ; margin-right: 0; margin-bottom: 0; margin-left: 0 )
if there are three values: margin: 0 10px 0
( means magin-top: 0; margin-right and margin-left: 10px; margin-bottom: 0; )
if there are two values: margin: 10px 0;
(means margin-top and margin-bottom : 10px ; margin-right and margin-left: 0 )

semicolons between different style settings please ( so text-align and margin had to be separated by semicolon )

allowed values for text-align: left|right|center|justify|initial|inherit;

All this is not bad, we are all still learning. And no question is too stupid – only not asking is stupid.

This is something that could not work:

p style="text-align: margin 0.0.0.0;"

text-align: ?
margin : no colon is noted above – and no dots between the values (0 0 0 0) – if all have the same value shorten to:
margin: 0

i do not know why there had to be a p-tag but if so – a closing p-tag had to be there too

<p style="text-align: left;  margin: 0;"><img class="alignnone size-full wp-image-111" src="https://hr-pflege.de/wp-content/uploads/2021/09/1.png"/></p>

.avia_mega_div > ul.sub-menu > li > ul.sub-menu > li > a > span.avia-bullet,
.avia_mega_div > ul.sub-menu > li > ul.sub-menu > li > ul.sub-menu > li > ul.sub-menu > li > a > span.avia-bullet { display: none }

if it is realy a custom ID it will be:
#portfolio-style {… } ( it is change anyway to not uppercase )
.portfolio-style is a class

Ist der Menupunkt denn noch ein Mega-Menu? – Sind denn da Untermenupunkte? Und warum – wenn du Sie doch ohnehin ausblenden möchtest?
Hat der Menu-Punkt immer noch die gleiche ID (12984) ?

Nächster Punkt. Das ist ja ohnehin auf display : none ! der hover style ist der, der interessiert – also versuche:
__________
Is the menu item still a mega menu? – Are there submenu items? And why – if you want to hide them anyway?
Does the menu item still have the same ID (12984) ?
The mega-menu is on default allready on display : none ! – the hover style is the one that interests – so try:
____________
maybe try better:

#menu-item-14445:hover .avia_mega_div {
   display: none !important;
}

be more specific on your selectors.
Maybe you give custom ID’s or custom classes to those table.

and you realy replaced your code ( on phone-info input field ) with mine ???

Yes – i found that link too – but i thought that there is in the meanwhile a solution from firefox til now.
See Date ot that topic: Opened 5 years ago Closed 5 years ago

dear mods, you no longer have to thank there – and certainly not so often :lol: ;)

But wait til a mod looks into that topic here again. There must be a reason to exclude the audio-player from mce.

can you try this in your child-theme functions.php:
see : Link

function av_change_logo_link_for_polylang_lang($link){
    if(pll_current_language() == 'en'){
        $link = "https://kriesi.at";
    }
    return $link; 
}
add_filter('avf_logo_link','av_change_logo_link_for_polylang_lang');

on default we can try this too – i do not test it yet as if clause:
if (get_locale() == 'en_GB') {

well – borlabs offers an iframe option.

• something like this placed on that page in a codeblock element:
  <div id="youtube-film" class="mfp-hide">[borlabs-cookie id="youtube" type="content-blocker"]<iframe width="100%" height="800" src="https://www.youtube-nocookie.com/embed/Uzjt3fvIlnY" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>[/borlabs-cookie]</div>
  The mfp-hide class will ensure that the div in the codeblock isn’t visible.
• your button is linking to that ID: #youtube-film ( if you got more than one film – each got his own id ) for each a unique div with that id (could be in the same codeblock)
• Give a custom-class to your button!
• Then you had to make your own magnificPopup script to open that class in an inline popup ;)
  the custom-class as trigger with midclick=true, type= 'inline', delegate: 'a', as option

Link
maybe you include in that script outside that magnificPopup function
$('.custom-class').find('a').addClass('no-scroll');

PS: it will work – but with two buttons on that slider we had to find better selectors ! otherwise the second button will be triggered too.

as mentioned above give a custom-class in this case to the slider

function inline_popup_youtube_link() { 
?>
<script type="text/javascript">
(function($){
$(window).on('load', function () {  
	$('.custom-class').find('a[href*="youtube"]').addClass('no-scroll');
	$('.custom-class').magnificPopup({
		delegate: 'a[href*="youtube"]',
		type:'inline',
		midClick: true,
	});
 });   
})(jQuery);
</script>
<?php 
}
add_action('wp_footer', 'inline_popup_youtube_link', 9999);

PPS: because the link isn’t really a youtube link ( remember the link goes to that div with ID: #youtube-film )
if you like to use it on other places – the ID must have a string with “youtube” maybe you can name them #youtube-1, #youtube-2 etc.

OR choose as selector: for the anchor : a[href^="#"] ( replace it on both lines ) – it means the link starts with #
But then the second button in the slider must not be an anchor link of the page. This would also fall into the trigger.
________
Das dort die Vorschaubilder von Youtube gezeigt werden in einer lokalen Version ( daher meine Frage oben ) – wird bei dir nicht der Fall sein !
Es wird das Standard Borlabs Preview image gezeigt werden.
Da habe ich ordentlich borlabs und youtube kenntnisse mit eingebracht und eigene Scripte geschrieben.

Yes – but he is right even on the newest Enfold – the fixed background is not fixed in firefox browsers.
