How to make modal close on click outside

Answer 1

This is working for me: I have an image inside of the modal window, so if someone click outside the image (centered):

html code:

ccs code:

#modal_div {
        display: none;
          position: fixed; 
        z-index: 1; 
        left: 0;
        top: 0;
        width: 100%; 
        height: 100%; 
        overflow: auto; 
          background-color: transparent;
}

#image_in_modal_div {
       left: 50%;
       top: 30%;
       position: absolute;
}

mixed jquery and javascript code:

$( document ).ready(function() {

    $("#element_that_opens_modal").click(function(){
        $("#modal_div").show();
    });

    window.onclick = function(event) {
       if (event.target.id != "image_in_modal_div") {
          $("#modal_div").hide();
       }
    }

});
