Allow thumbnails links for IE10 and below

You’ve probably noticed that some features of Customizr are not well interpreted by some outdated versions of Internet Explorer. The beloved zoom effects on the thumbnails for the featured pages and posts lists, for example, are not supported by them.  Unfortunately, thumbnails links does not work either. 

Add this snippet to your child theme functions.php  to work around this issue.

add_action('wp_footer', 'ie_thumbnails_links');
function ie_thumbnails_links(){
?>
    <script type="text/javascript">
        jQuery(document).ready(function () {
            !function ($){
                "use strict";
                
                $.ThumbsWithLinks = function() {
                     // grab all a .round-div 
                    var $round_divs = $("a").filter(".round-div");
                    // grab all wrapped thumbnails
                    var $images = $(".thumb-wrapper img");
                    
                    $images.each( function(i) { 
                        // let's wrap the thumb into the round-div link
                        $(this).wrap('<a href="' + $( $round_divs[i] ).attr('href') + '" title="' + $( $round_divs[i] ).attr('title') + '"></a>'); 
                        // let's remove now useless round-div
                        $($round_divs[i]).remove(); 
                    });
                }
            }(window.jQuery);
            
            // detect if the browser is IE
            var ua = window.navigator.userAgent;
            var msie = ua.indexOf ( "MSIE " );

            if ( msie > 0 )
                // call our function for IE versions less than 11
                if ( parseInt( ua.substring ( msie+5, ua.indexOf (".", msie ) ) ) < 11 )
                    jQuery.ThumbsWithLinks();
        });
    </script>
<?php
}
