The features and amenities section from property page is displayed using the function estate_listing_features(). This function is in listings.php at line 102.

In this function there is a if around line 116

if($show_no_features!='no'){

Here we check if the theme is set to show also the features that are NOT present on that property.

The code that actual  display an items is

$return_string .= '<div class="listing_detail col-md-4"><i class="fa fa-check"></i>' . trim($value) . '</div>';

If you want to select via css the “Features and amenities” area on property page you an select it by id

#accordion_prop_features{

}
