Hi,
Thanks for your patience, I only asked for access to your test page so we would be looking at the same thing and so I would  not need to recreate your layout on my site, nonetheless I created 1/5 + 3/5 + 1/5 columns with a gallery with large image on top and thumbnails below, and a color section with 100% min-height below that to simulate the rest of the page.

My sticky header is 90px, although I see yours is 157px.
My first impression of the layout is that the large gallery image on top is almost the full height of the screen, so the thumbnails are not really seen, I added 50px right & left padding to the 3/5 column and that helped a little

Adding 150px right & left padding to the 3/5 column was better

but I get the feeling that you want the large image to be as large as possible, and not so much empty space on the sides, so having it sticky would make the thumbnails hard to see. I tested Guenni007’s solution at: https://webers-testseite.de/ajax-gallery/#av_section_2 and other than adjusting the top: 70px to match my header it seems to work well.
But ypur current masonry layout https://www.thomashenthorne.com/26-mooring-road-san-rafael-ca/#av_section_42
seems much better because the user can see the thumbnails, it fills the page and the user can easily navigate the lightbox images (slideshow).

Hey Dave Chapple,
Since upwork is not available at fontello, you will need to convert your upwork image into a iconfont and add the correct code to your functions file:

function avia_add_custom_icon($icons) {
  $icons['tiktok'] = array( 'font' =>'fontello', 'icon' => 'ue800');
  return $icons;
  }
  add_filter('avf_default_icons','avia_add_custom_icon', 10, 1);
  
  function avia_add_custom_social_icon($icons) {
  $icons['TikTok'] = 'tiktok';
  return $icons;
  }
  add_filter('avf_social_icons_options','avia_add_custom_social_icon', 10, 1);
  add_filter('avia_social_share_link_arguments', 'avia_add_social_share_link_arguments', 10, 1);
  function avia_add_social_share_link_arguments($args){
      $tiktok = array('tiktok' => array("encode"=>true, "encode_urls"=>false, "pattern" => "https://www.tiktok.com/", 'label' => __("Share on TikTok",'avia_framework')));
      $args = array_merge($tiktok, $args);
      return $args;
  }

You will need to adjust the code to suit your icon which has a custom code from fontello.

Hi,

Hey grimkraneveld,
We could take a look and your page if you post a link to it with a admin login. There could be the possibility  that the popup script is conflicting with the built-in popup script, which you can disable  in the theme sttings and check again. Or some layerslider premium addon require the full paid version of the layerslider and not the free version that comes with the Enfold theme.

Hey Sebastian,
Your container max-width is 1200px and contains margin & padding:

Try this css and adjust to suit:

.responsive .page-id-3603 #av_section_4 .container {
    max-width: 100%;
    padding: 0;
}
