Mh – that class isn’t added to mediaelementwrapper video : av-mediajs-loaded in Safari!
so the trigger for that function does not exist on safari.
On Firefox and Chrome this class is added when the video has fully loaded.

your start point was an imported Demo File? and you now like to delete not used Example Pages
Yes you can delete them – all at once – just mark them in the list view and choose “move to bin” and then “apply”

These pages are moved to the bin. However, if you’re sure, you might as well empty the bin now. Especially since it is only then possible to reassign the page name in the permalinks. Many people are surprised when they try to create a new contact page, for example, and it is then listed in the permalinks as /contact-2.

Yes i know – but exactly this code does work on Safari too on former installations.

btw. : this part is only for child-theme shortcodes replacement and should stay in your child-theme functions.php

add_filter('avia_load_shortcodes', 'avia_include_shortcode_template', 15, 1);
function avia_include_shortcode_template($paths){
  $template_url = get_stylesheet_directory();
      array_unshift($paths, $template_url.'/shortcodes/');
  return $paths;
}

if you look in dev tools – the id ( postid-123 or page-id-123) you can see at the body tag ( #top )
be careful of the hyphen posts do have only one no hyphen between post and id.

try this – i added contact form 7 support – so when the shortcode for contact-form 7 is used the recaptcha script is loaded – otherwise not.

function prohibit_google_recaptcha( $prohibited ){
  global $post;
  if( ! $post instanceof WP_Post ){
    return $prohibited;
  }
  

  /*** 1) Check to load recaptcha on given page ID's only*/
  $allowed = array( 1396, 1407 );
  $prohibited = in_array( $post->ID, $allowed ) ? false : true;
  
  /*** 2) Check to not load recaptcha on given page ID's - load on all others*/
  $not_allowed = array( 12, 25, 35 );
  $prohibited = in_array( $post->ID, $not_allowed ) ? true : false; 

  /*** 3) Get content to check (ALB or normal content) ***/
  $content = Avia_Builder()->get_post_content( $post->ID );
  $prohibited = ( false !== strpos( $content, '[contact-form-7 ' ) || false !== strpos( $content, '[av_contact ' ) ) ? false : true;

  return $prohibited;
}

add_filter( 'avf_load_google_recaptcha_api_prohibited', 'prohibit_google_recaptcha', 10, 1 );

i only use 3) Option to check if contact shortcodes are used.

I do not see your private content because i’m participant as you are.

But : a line-break is a break ! if you do not want to have between your images a little space – do insert one image by the other ones without any break
and give a custom-class to the text-block itself like f.e.: images-block

then:

.avia_textblock.images-block img {
display: block
}

if you are in textmode of Editor in Textblock ALB you will see this:

the :

color: currentColor !important;

is responsible for the font color. Erase only that line and see if your will be happy with that.

did you copy&paste the line above?
I don’t see any “&” so it can hardly be from my snippet up there.

Where did you paste the code?

And can you please post an example code you inserted to your menu?

i can see all the svg (Firefox, Chrome and Safari ) on your site mentioned above ( but https://www.flo-haaf.de )
( but your logo on top comes from . https://ftp.flo-haaf.de )
so maybe all your browser cache had to be cleaned ? You will surely have checked your site frequently with said browsers, so they may still have the old links in there.

did you try that button mentioned above?

die original css Anweisung für Überschriften kommt aus:

.main_color h3

versuch also mal ob
h5.gelb etc nicht zum Ziel führt

oder eben

.gelb {
color: gelb !important
}

hast du irgendwelche Caching Tools laufen ; das Merging von Enfold ( Enfold oder Enfold-Child – Leistung ) an – dann refreshe auch diese Files.
denn selbt im Textblock ALB Element gesetzte Farbe für die Schrift überschreibt die inline gesetzte nicht:

Läuft bei dir schon WP 5.6 – siehe: https://kriesi.at/support/topic/problems-after-updating-to-wordpress-5-6-read-this-first/

on my installation this drag&drop works well – but

However, I often use this small button on the right side for layouts with a lot of content.
For this it is also useful to collapse the dashboard.

the ALB Elements Bar is then sticky on top – you can scroll the content underneath.

After Work is done you have nearby the ALB Elements Bar the buttons for updating the post:

how did you insert that code – in textblock element?
if you use this button to enter a break it will insert that code :

<br class="avia-permanent-lb" />

the br tags with classes remain in the DOM

Try:

#top.postid-3540 h2 {
   margin-bottom: 800px!important;
}

heading-tags and p-tag and body and div do not have a dot in front – i hope it is only 80px ;)
