interacting through svg-mask not possible

Question

I want to cover my whole website despite a small circle that follows the cursor. So I made a svg with a circle-mask that updates it's position via jquery. But now all my elements below are not clickable, because the svg lays in front of them. Is there a solution how to solve this?

<svg viewbox="0 0 100 50" width="500%" height="500%" id="mouseoverlay" class="mouseoverlay" style="position:fixed;">
<defs>
    <filter id="gauss">
        <feGaussianBlur in="SourceGraphic" stdDeviation="0.4"/>
    </filter>
    <mask id="mask" x="0" y="0" width="100" height="30">
      <rect x="0" y="0" width="100" height="100" fill="#fff"/>
     <circle cx="50" cy="25" r="4.5" filter="url(#gauss)" />
    </mask>
</defs>
<rect x="0" y="0" width="100" height="100" mask="url(#mask)" fill="#bbb" fill-opacity="1"/>    

$(document).mousemove(function (e) {
        var bodyOffsets = document.body.getBoundingClientRect();
        var fensterhoehe = window.innerHeight;
        var fensterbreite = window.innerWidth;
        tempX = e.pageX - (fensterbreite*2.5);
        tempY = e.pageY - (fensterhoehe*2.5);
        $('#mouseoverlay').css({'top':(tempY - scrollY),'left':tempX}).fadeIn("3000");
}

Answer 1

You can take a look at pointer-events.

ex

var tempX;
var tempY;

$(document).mousemove(function (e) {

        var bodyOffsets = document.body.getBoundingClientRect();
        var fensterhoehe = window.innerHeight;
        var fensterbreite = window.innerWidth;
        tempX = e.pageX - (fensterbreite*2.5);
        tempY = e.pageY - (fensterhoehe*2.5);
        $('#mouseoverlay').css({'top':(tempY - scrollY),'left':tempX}).fadeIn("3000");
});

#mouseoverlay {pointer-events:none;}
