css depends on the place where you show it – f.e. in the top header:

#top #wrap_all .av-social-link-bluesky:hover a {
    color: #fff;
    background-color: #1185fe;
}
#top #wrap_all .av-social-link-bluesky a svg * {
    fill: var(--enfold-header_replacement_menu_color);
}
#top #wrap_all .av-social-link-bluesky a:hover svg * {
    fill: #FFF
}

now – thanks for the admin permissions.

i did what i mentioned above: for the thumbs in grid i take the portfolio size (495×400)
using that snippet to have original images in the ajax preview image ( on imagify you have choosen to have no compression – so original image might be of less file-size than the recalculated large image-size )
and disabeling the enfold option to use lazyloading ( maybe the option of wp-rocket is better )

but with these changings – you can see a much better loading performance.

in additon – i decided to show on lightbox the full image ( because your large recalculated images are much bigger in file-size than the full one )
and to have no scroll on background – on opend lightbox.

you know that and how you can add your own social media icons to the enfold system.

can we influence the image shown in the ajax preview ( that img insided avia-gallery-big ) – it seems to use the recalculated “large” image.
But as you know this might be bigger in file size than the original uploaded image!
I can not find a filter to adjust it.

or could we influence it by
$params['preview_size'] = apply_filters( 'avf_ajax_preview_image_size', 'gallery' );

i can find this in portfolio.php

//	create array with responsive info for lightbox
	$img = Av_Responsive_Images()->responsive_image_src( $attachment->ID, 'large' );

bring it to full will often reduce file-size – as you know that Enfold standard compression leads to bigger file-sizes on large image.

ok – i found the place to change in gallery.php (line 757)
$prev = wp_get_attachment_image_src( $attachment->ID, $preview_size );

if we would use :
$prev = wp_get_attachment_image_src( $attachment->ID, 'full' );

looking to his page f.e.:
the krebs-treppen-systeme-gelaender-system30-3.jpg is 121kb
but krebs-treppen-systeme-gelaender-system30-3-1030×839.jpg is 268kb

the whole page got over 112MB images – and could be reduced to a half size.

you can find the defintions of standard icons on enfold/includes/config-enfold/init-base-data.php

Easy Slider is on default using:

'svg__next_big'  	=> array( 'font' => 'svg_entypo-fontello', 'icon' => 'right-open-big' ),
'svg__prev_big'  	=> array( 'font' => 'svg_entypo-fontello', 'icon' => 'left-open-big' ),

The Filter you can use to change these icons is: avf_default_icons

you can use it like this in your child-theme functions.php:

function avia_replace_default_icons($icons){
// e.g.: changed by uploaded svg files - using the ID's and the font-name is svg_wp-media-library
	$icons['svg__prev_big'] =  array( 'font' =>'svg_wp-media-library', 'icon' => '50913');
	$icons['svg__next_big'] =  array( 'font' =>'svg_wp-media-library', 'icon' => '50591');     
	return $icons;
}
add_filter('avf_default_icons','avia_replace_default_icons', 10, 1);

but: What is the font-name of your uploaded icon-set

you find that information on :

now f.e. if you like to replace these standard icons by icons of the iconset : medical

function avia_replace_default_icons($icons){
	$icons['svg__prev_big'] =  array( 'font' =>'medical', 'icon' => 'uf101');
	$icons['svg__next_big'] =  array( 'font' =>'medical', 'icon' => 'uf135');     
	return $icons;
}
add_filter('avf_default_icons','avia_replace_default_icons', 10, 1);

you can find those font icon codes f.e. on trying to place that icon you like to have and hover it :
( it is the value inside the brackets – without that backslash)

Hi Rikard,

I have installed the new Enfold version and updated the PHP. Everything went well! The thread can be closed.

Best,
Marieke

This is an Enfold CSS that controls the respective element.
In this case it can be found here: /enfold/config-templatebuilder/avia-shortcodes/testimonials
But at least the Quick CSS variant will remain intact when you update Enfold.

Perhaps the developers should set this setting to this value (“Block and Hide reset all options button”) by default after Enfold Activation. Too many people have accidentally pressed this button despite a warning pop-up.
