hier kannst du mal eine Umsetzung mittels Grid Layout nachvollziehen:
Ziehe den Screen mal kleiner als die 1200px dann siehst du wie die responsive Setzung arbeitet. Man müsste dann noch für sehr kleine screens etwas machen.

Sehr gute Einführung:

und
Playground: https://grid.layoutit.com/

for 2)
btw: that is not a blog setting – blog is context index
these are archive pages.

put this to your child-theme functions.php:

add_filter("avf_post_slider_args", function($atts, $context) {
  if( $context == "archive" ) {
    $atts['type']  = 'grid'; 
    $atts['columns']  = 4;
    $atts['preview_mode'] = 'custom';
    $atts['image_size'] = 'magazine'; // if you want to have different source Images for that setting
  }
  return $atts;
}, 10, 2);

by the way – the source site of evidenz.de is an Enfold site too. Maybe you can ask them what you should do to hamper that scrolling.
The script is small enough to not load from their site- download it – make some change to the script and compress it (f.e. on https://jscompress.com/) to have a minified version of it. enqueue that minified script from your own server.

ok – that is something different. But i think the script does not work as it should anyway.
because a modal window should actually be created – right?
” // PG: this version of the js-file handles the modal without the need of jQuery ”

Then the scroll position of the modal window makes sense. And mike pointed out where the code is for doing that.
For me it looks like the modal should open on page load – and the top of that iframe inside the modal window is then on top.
But there is no modal window.

can you please post the code of the code-block element here ( use the code tag from the options above please )
________
Was wird denn dort innerhalb des iframe angezeigt? woher speist sich der Inhalt? Meinst du nicht, das es auch mit Enfold mitteln gehen sollte? – ohne extra scripte?

What is displayed within the iframe? Where does the content come from? Don’t you think that it should also work with Enfold means? – without extra scripts?

may i see your example page too?
As participant i do not see your private content area. Or describe your problem in more details.
F.e. a lot of users say iframe and they mean a lightbox window.

do you belong to the marked text just before the caret starts with the new word?

try:

.av-marked-text .av-rotator-text-single {
	background-color: transparent !important
}

the color of changing words and carret:

#top .av-rotator-container .av-rotator-text-single {
  color: inherit !important;  /***** if it should get the color of the other words  ***/
}

.av-caret .av-rotator-text-single:after {
  border-color: #FFF;   /***** change to your needs ***/
  /***** display: none;   if you do not want to see any carret ***/
}

see my example ( with special text-shadow) : https://webers-testseite.de/park13

PS: because i do not see your setting i could not give you better advice. Maybe a multiline ( with the rotating text on a new line ) has a bit different selectors.

So – this is not provided with the Enfold Google Maps element.
But what you could do is place a dummy marker at the top of the list, with a custom marker. Then you upload a completely transparent png file. Since the top of the list determines the center of the map, you could achieve your goal.

yes – or you decide to influence the placeholder text and input text.

#top .header_color input::placeholder,
#top .header_color input[type="search"] {
  color: #fff !important;
}

or a combination:

#top .header_color input::placeholder,
#top .header_color input[type="search"] {
  color: #fff !important;
}

#top .header_color #s {
	background: linear-gradient(-90deg,#7ea338,#3b4b1e);
}

you can have it in between the first and second column:

#footer .flex_column.first  {
  border-right: 1px solid rgba(255,255,255,.3);
}

or more nearby the content of your first column:

#footer .flex_column.first .widget {
  border-right: 1px solid rgba(255,255,255,.3);
  padding-right: 30px;
}

on my iPad i do not see any blue pop ups.
have you erased your device cacheing?

can you make the link to your page public? releasecfs etc. i found a lot about you – but i do not see the “highlight” you are talking about.
Presumption would be the background of: .html_stretched #wrap_all

ok – thanks

maybe you decide to style it a little:

#lang_sel_list {
  display:  inline-block !important;
  background-color: rgba(255,255,255,0.3);
  -webkit-backdrop-filter: blur(3px);
  backdrop-filter: blur(3px);
  border-radius: 5px;
  padding: 5px ;
}

#lang_sel_list > ul {
  display:  flex !important;
}

#lang_sel_list .wpml-ls-item {
  position: relative;
  left: 0 !important;
}

#lang_sel_list .wpml-ls-link {
  text-decoration: none !important;
}

#lang_sel_list .wpml-ls-link:hover {
  background-color: rgba(0,0,0,0.3);
}

on WPML – Languages – there is in the options : “Menu language switcher ” Add a new one.
Then you see the options for that menu you choose

if the switchers are not inside a menu – you can scroll down a bit and have : “Custom language switchers” mark it and customise it there.

i do not have an enfold setting with header on the left and WPML – so i can not test it for you.
if that position does not belong to these settings:

try: https://kriesi.at/support/topic/wpml-language-switcher-8/#post-695476

but: i think these filters and action hooks are deprecated now. on : class-avia-wpml.php lines 86 to 110 there are more options to influence. i think a mod should instruct you with these new “options”

or read this for more info: https://wpml.org/documentation/theme-compatibility/enfold/#enfold-language-switcher

when you download the files from transfonter ( you can pick out from that zip the woff and ttf files into a folder with name you like to give.
You do not need any other files inside your zip than the pure font-formats!
F.e. name that folder for all the open-sans fonts “Open Sans” – see:

zip this folder ! BUT be carefull on your Mac OS – because OS will have inside that folder hidden files ( this is typical for OSX folders ).
Some of the OSX Compressor Tools like BetterZip have an option to zip for PC ( then these hidden system files will not be in this zip file)
these are your “MACOSX (font-family: macosx) “. ( But you can erase these “Fonts” from Font Manager.

This “4ab16c3952a6f71bb538afe303ac6379.woff2” happens because you have uploaded directly the downloaded zip file.

if you rename the zip.file to f.e “Open Sans” then the Font Manager will show the folder name as Font Name (green) – and the filenames will end in the original implemented postscript font-family name.
