Add CSS styled marker to google maps

Question

Can someone please advise how I could add this animated marker to the below google maps API.

The below is the standard google maps api code with option to give imag

Here's a modified version of the pulse animator you mentioned that I'm using that works. Basically you create an overlay (https://developers.google.com/maps/documentation/javascript/customoverlays) that you then position by attaching to a marker point.

To have the pin and animation created from CSS I believe you'll need to set the pin image blank and to the correct size with something like this if you'd like it to be clickable through the marker.

var image = {
  url: '/images/blank.png',
  size: new google.maps.Size(100, 39),
  origin: new google.maps.Point(0, 0),
  anchor: new google.maps.Point(50, 39),
  };

Then make sure the overlay is drawn on the correct pane

var pane = this.getPanes().overlayImage; (contains the marker foreground images.)

My implementation provided below is slightly different because I decided to use a pin image and only the animation part. I'm going to draw on the overlayShadow so the animation goes behind the image I use for the marker.

JS

var animatedOverlay;

// Define the animated overlay, derived from google.maps.OverlayView
function PinAnimation(opt_options) {
    this.setValues(opt_options);
    var div = this.div_ = document.createElement('div');
    div.id = 'holder';

    var span = this.span_ = document.createElement('span');
    span.className = 'pulse';
    div.appendChild(span);
};

PinAnimation.prototype = new google.maps.OverlayView;

PinAnimation.prototype.onAdd = function() {

     //Overlay shadow puts the animation behind the pin
     var pane = this.getPanes().overlayShadow;
     pane.appendChild(this.div_);

     // Ensures the PinAnimation is redrawn if the text or position is changed.
     var me = this;
     this.listeners_ = [
          google.maps.event.addListener(this, 'position_changed',
               function() { me.draw(); }),
     ];
};

// Implement onRemove
PinAnimation.prototype.onRemove = function() {
     this.div_.parentNode.removeChild(this.div_);

     // PinAnimation is removed from the map, stop updating its position/any other listeners added.
     for (var i = 0, I = this.listeners_.length; i < I; ++i) {
          google.maps.event.removeListener(this.listeners_[i]);
     }
};

// Set the visibility to 'hidden' or 'visible'.
PinAnimation.prototype.hide = function() {
    if (this.div_) {
        this.div_.style.visibility = 'hidden';
    }
};
PinAnimation.prototype.show = function() {
    if (this.div_) {
        this.div_.style.visibility = 'visible';
    }
};

// Implement draw
PinAnimation.prototype.draw = function() {
    var topPadding = 0;
    var sizeHeight = 50
    var sizeWidth = sizeHeight;
    var centerX = sizeWidth/2;
    var centerY = sizeHeight/2;

     var projection = this.getProjection();
     var position = projection.fromLatLngToDivPixel(this.get('position'));
     var div = this.div_;
//Adjust overlay position to be centered over the point
     div.style.left = position.x-centerX + 'px';
     div.style.top = position.y-topPadding-centerY + 'px';
     div.style.display = 'block';
};

//Set marker and draw overlay
function setMarker(location) {

    var maps_location = new google.maps.LatLng(location.latitude, location.longitude);

    var marker = new google.maps.Marker({
        position: map_location,
        map: map,
        icon: marker.png,
        title: 'Hello World!'
        });

    animatedOverlay = new PinAnimation({
        map: map
    });
    animatedOverlay.bindTo('position', marker, 'position');
    animatedOverlay.show();
}
