Fancybox full width

Question

I'm new to coding and I'm trying to have every fancybox ONLY in my homepage full width and responsive (eg) but non of these options have done the job (fitToView, autoSize or aspectRatio).

jQuery

jQuery(document).ready(function() {
jQuery( "#site-logo" ).click(function( e ) {
    alert( "As you can see, the link no longer took you to jquery.com" );
    jQuery.scrollTo( 0 , 1000, { easing:'easeInOutExpo' });
$(".fancybox").fancybox({
    helpers : {
        media: true 
        },
        width: 1600,
        height: 870,
        aspectRatio: true,
        scrolling: no,
        });
    });
});

Answer 1

Try adding an autoSize false, removing the aspectRatio and changing the width to "100%":

jQuery(document).ready(function() {
    jQuery( "#site-logo" ).click(function( e ) {
    alert( "As you can see, the link no longer took you to jquery.com" );
    jQuery.scrollTo( 0 , 1000, { easing:'easeInOutExpo' });
    $(".fancybox").fancybox({
        helpers : {
            media: true 
        },
        width: "100%",
        height: 870,
        autoSize: false,
        scrolling: false
        });
    });
});

For anyone else looking in future searches I had the same problem where I needed the image (pop up) to be full width, even if the image has overflow height so I wanted it to be scrollable. Anyways I hope this helps someone in the future.

<script type="text/javascript">
jQuery(document).ready(function($) {
    $(".fancybox").fancybox({
        autoSize : true,
        scrolling : 'auto',
        fitToView : false,
        width : 'auto',
        maxWidth : '100%',
    });
});
</script>
