image instead of icon

Hey Manuela,
Thank you for your patience, to use an image instead of an icon in the icon box element, add a custom class to the icon box you wish to change, for this example we will use custom-image-icon note there is no dot before the class.

then add this code in the General Styling ▸ Quick CSS field or in the WordPress ▸ Customize ▸ Additional CSS field:

.custom-image-icon .iconbox_icon {
background-image: url(https://kriesi.at/wp-content/themes/kriesi/images/logo.png);
height: 23px;
background-size: contain;
background-repeat: no-repeat;
background-position: 50% 50%;
}
.custom-image-icon .iconbox_icon:before { display: none; }

the expected results:

To use multiple images use a different class for each image.
After applying the css, please clear your browser cache and check.

Best regards,
Mike
