The child theme name does not appear in the frontend. So why rename the child theme?
Just to obfuscate the Enfold origin – this involves much more than just changing the name.

By the way – it is a good idea – to have a backup on this. And perhaps if you rename child and parent theme to save your theme settings file and maybe the quick css.

As long as you do not change the reference in the style.css of the child theme to the parent element, you can rename it as you wish.
Enfold even offers you the option of renaming the stylesheet of the Theme using a filter.
but read here carefully on the docu: https://kriesi.at/documentation/enfold/personalize-theme/

function avia_change_filename($stylesheet){
return 'myfilename';
}
add_filter('avf_dynamic_stylesheet_filename', 'avia_change_filename');

by the way dear dev/mods: on docu this snippet is listet with myfilename.css – this will lead to myfilename.css.css – so above only the name is neccessary – the css extension is added to the filename by default.

I must say, however, that those who are able to examine such things more closely will always recognise the basis of the theme.

if you want it 5 columns on desktop and on mobile always 2 column:

#top .settore-attivita .entry-content-wrapper {
  display: flex;
  flex-flow: row wrap;
  justify-content: space-between;
}

#top .settore-attivita .entry-content-wrapper:before,
#top .settore-attivita .entry-content-wrapper:after {
  display: none !important;
}

#top .settore-attivita .entry-content-wrapper .flex_column {
  flex: 0 1 19%;
  width: unset !important;
  margin: 0px;
}

@media only screen and (max-width: 767px) {
  #top .settore-attivita .entry-content-wrapper .flex_column {
    flex: 0 1 48%;
  }
}
}

you see how it works ?

look to the layout image again – the color-section with your columns should have the custom-class : settore-attivita
you gave to it an ID : settore-attivita

If you like to have only 2 columns beside – even on mobile phone just get rid of last media query rules:

@media only screen and (max-width: 549px) {
  #top .settore-attivita .entry-content-wrapper .flex_column {
    flex: 1 1 100%;
  }
}

If you have looked at my suggestion, I will remove your pictures.
the ID is only for a anchor navigation if you like

https://webers-testseite.de/giulia/

can you please exclude the text-block with the heading to an extra section before that section with all those “Settori”
by the way – why don’t you use for a heading a heading element instead of putting the heading inside a text-block element?

after that – we can handle the whole container as a flex container
no need for a second color-section handling the other layouts for responsive design.

i got no troubles on classic editor – only if i switch to advanced layout editor – i had these glitch

but indeed the clearing option is much better. so use instead:

function admin_head_mod() {
echo '<style type="text/css">
	#postbox-container-2 { clear: left; }
	.index-php #postbox-container-2 { clear: none; }
</style>';
}
add_action('admin_head', 'admin_head_mod');

well it is in the enfold folder : includes.
If you make a subfolder to your child-themes folder : includes and put the edited loop-search.php inside that folder the search results page will show featured images.
here is on basis of enfold 6.0.4 the edited file:
see: https://pastebin.com/3nAyB6Gr
Changes are made on line 50ff . I inserted some classes to better select them and put the link on the image too.
download: https://pastebin.com/dl/3nAyB6Gr

a little css is needed

.search-result-image {
    display: block;
}
.search-result-image img {
    width: 120px;
    border: 1px solid #aaa
}
.search-result-image svg {
  width: 120px !important;
  height: auto;
}
.search-result-image img {
    width: 120px;
}
.search-result-image {
    float: left;
    margin-bottom: 20px;
    padding-right: 30px;
}

PS: on line 52 you can see that i took the medium image format as source (and not the thumbnail image) – you can change that to anything you like – but medium got one advantage – it is a non cropped image format.

And that is exactly what the NY Page shows – the top video fades out the video in the middle of the page fades in.

Rikard already said it : in your example – there is the closing strong tag correct with an /
The slash indicates that the tag is closed – on top you only have opening strong tags !

Podcast: Afhængige Parforhold<strong>.</strong>

PS: only a few tag seems not to have a closing tag – but if you look nearer f.e. to an img tag the opening tag ends with />
hr and br tags need no closing tag ( although old fashioned guys like me write: <br />)

you can try in child-theme functions.php:

function custom_avf_avia_logo_link_title( $link_title ){
return 'title="Homepage"';
return $link_title;
}
add_filter( 'avf_avia_logo_link_title', 'custom_avf_avia_logo_link_title', 10, 1 );

I just wanted to use it as a crutch.
They encode all the movies to their specifications. That way you can be sure that they will run smoothly on as many platforms as possible. Then you can download the result and use it as a self-hosted video.

i can not say something about the video – i think it was a pixabay share.
but if you like to send me a link of your video i test it in my environment.
you find contact info under my nick

on my mac – IINA shows : h264, 1288×720 with 29,97fps

and if you want to bring the containers below the title to the same top position:

function admin_head_mod() {
echo '<style type="text/css">
  .avia-advanced-editor-enabled #post-body-content { float: none; }
  .avia-advanced-editor-enabled #normal-sortables .postbox#avia_builder:first-child { margin-top: 0; }
</style>';
}
add_action('admin_head', 'admin_head_mod');

dear dev : it concerns to class avia-advanced-editor-enabled
why the other browser can manage that – i do not know – i look now inside avia-builder.css – maybe there is something missing.

because I don’t use the Gutenberg stuff – someone else will have to check if it needs fixing there too.

With the nickname, it’s not too hard to find your site. And when I see container that small (1010px), I know it’s not intentional. So there must be a rule in your ruleset that is not set correctly.

That css rule is not closed by a curly bracket.

Insert after the semicolon a curly bracket!

.gform_wrapper.gravity-theme .gf_progressbar_percentage.percentbar_orange {
	background-color:var(--enfold-main-color-primary);

don’t know if an @import rule works well over quick css – but is unusual.

if your question does not concern your own website – then I am sorry, but it should be changed anyway.

PS: csslint.net shows a parsing error at the pseudo-class: is
but from my point of view that is correct.

sadly the topic is closed: . https://kriesi.at/support/topic/search-function-with-link-list/

what i got so far:
https://enfold.webers-webdesign.de/pages

this is only for pages ( if you like to have that for posts – just change the post-type )
i managed it by a custom shortcode – then place this as : [glossary] on your page

function az_index($post_id) {
    $AZposts = get_posts(array(
        'numberposts'       => -1,
        'post_type'         => 'page',
        'orderby'           => 'title',
        'order'             => 'ASC',
        // 'category'           => $cat
    ));

    $current = "";
    $nav = "";
    $postlist = "";
    foreach($AZposts as $AZpost) {
        $postLink = get_permalink( $AZpost->ID );
        $firstletter = strtoupper(substr($AZpost->post_title,0,1));
        if($firstletter != $current) {
            $nav .= "<span class='firstletters'><a href='#$firstletter'> $firstletter </a></span> ";
            $postlist .= "<h3 class='firstletter' id='$firstletter'> $firstletter </h3>\n";
            $current = $firstletter;
        }
        $postlist .= "<span><a class='postlink' href='".$postLink ."'>" . $AZpost->post_title.  "</a></span><br>\n";
    }

    print $nav . "<br><br>" . $postlist;
}
add_shortcode( 'glossary', 'az_index' );

and :

.firstletters {
  padding: 0 10px ;
  background: #900;
  margin-right: 5px;
  display: inline-block;
}

.firstletters a {
  color: #FFF;
  text-align: center !important;
}

i tried to have unordered list after the h3 headings – but i couldn’t find a way to do that ( loop is hard to find the place to insert that tags ) – maybe a mod got a good idea
