Hi Ismael I sent to you a very clear link. You must look in mobile version. In desktop all is ok. The issue is on mobile.

Tabs are all the same. For example the fist tab is exactly as like the second one. Both tabs hace titles but In the first I can see titles correctly. In the second title has problems. If I invert the tabs, first become correct, second one become with issue.
In all pages I have the same problem. The first tab is ok. Second, third… title disappears.

It’s clear that there is some bug in Enfold tabs.
Waitng for your answear please.

in other words – shrink only the logo the rest stays on position – white line erased.

#top #header_main > .container, 
#top #header_main > .container .main_menu .av-main-nav > li > a, 
#top #header_main #menu-item-shop .cart_dropdown_link {
  line-height: 244px !important;
}

#top #avia-menu::after {
  transition: opacity 1s ease;
}

#top #header.header-scrolled #avia-menu::after {
  opacity: 0;
}

ok – nice to have the page link (on your other topic it is shown):

there are links on the images too – but they could not be clicked because there is a full overlay of the grid-content
so no need for a script here

#top .grid-content {
  pointer-events: none;
}
/*** if you do not like to have that image white overlay:*****/

#top .grid-entry .image-overlay {
   display: none !important;
}

this will work too – but it is not needed here

function transfer_first_link_as_link_to_article(){
?>
<script type="text/javascript">
window.addEventListener("DOMContentLoaded", function () { 
  (function($) {
      $('.grid-content').each( function() {
        var LinkSection = $(this).find('.grid-entry-title a').attr('href');
        var LinkTarget = $(this).find('.grid-entry-title a').attr('target');
        if (typeof LinkSection !== "undefined"){
          $(this).on("click", function(){
            if (LinkTarget === "_blank"){
              window.open(LinkSection, '_blank'); 
            } else {
              window.location.href = LinkSection;
            };
          });
          $(this).css('cursor','pointer');
          $(this).find('.image-overlay').css('display','none');
        };
      });
  })(jQuery);
});
</script>
<?php
}
add_action('wp_footer', 'transfer_first_link_as_link_to_article');

When creating a custom element, the aim is to make settings for this element in advance and, if necessary, to block them directly for non-admins (possibly) editors (depending on your pre-selection see screenshot).

Ultimately, the aim is to define as many settings as possible in advance so that an author no longer has access to many of these settings (headings tag, position of the heading, captions etc., background-colors etc. . The image that you enter on creation of the custom slider is only used to set default settings for this slider. You can here hamper for example that the author got the possibility to insert videos to the slide.

Once your custom element has been created and is ready to be inserted into the layout, authors can insert as many images as they like using the predefined default settings.
And only the nonblocked Settings are editable.

btw:

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%;
  }
}
