Change Google Maps Infowindow Close Icon - graphics

Question

How can I change the default graphic for the Infowindow close button?

Answer 1

You can do it with CSS, like this:
img[src="http://maps.gstatic.com/intl/en_us/mapfiles/iw_close.gif"]
{ content:url("/img/own_close_button.png"); }
Works on:
Chrome 14.0.835.163
Safari 4.0.5
Opera 10.6
Most mobile devices (default browser)
Does not work on:
FireFox 27.0
IE 11.0

If you're using google maps API V3, then you might want to use the official add on infobox.

Answer 3

First you need to hide the default close icon:
.gm-style-iw button.gm-ui-hover-effect img {
display: none !important;
}
Second, force the default button (that holds the image) to have full opacity:
.gm-style-iw button.gm-ui-hover-effect {
opacity: 1 !important;
}
Third, set your own image and position it:
.gm-style-iw button.gm-ui-hover-effect:before {
display: block;
content: "";
background: url('assets/close-red.svg') center center no-repeat;
background-size: cover;
width: 8px;
height: 8px;
right: -19px;
position: relative;
}
Result:

With jQuery you can change the image file location. If I have an image button_close.png that is 16px in size:
jQuery('img[src="http://maps.gstatic.com/intl/en_us/mapfiles/iw_close.gif"]').livequery(function() {
jQuery(this).attr('width', 16).attr('height', 16).css({
width: '16px',
height: '16px'
}).attr('src', 'button_close.png');
});
Of course this only works as long as Google uses this file location.

Answer 5

button.gm-ui-hover-effect {
background: url(your-img.png) !important;
background-size: contain !important;
}
button.gm-ui-hover-effect img {
display: none !important;
}

Answer 6

Using what Dimitrije Djekanovic and Grant suggested, here is a working version for the current API version 3.49 (Mid-May of 2022):
/* hides the x image */
button.gm-ui-hover-effect > span {
display: none !important;
}
/* inserts the customized and clickable image instead */
button.gm-ui-hover-effect {
opacity: 1 !important;
background: url('close.svg') center center !important;
background-repeat: no-repeat !important;
background-size: 16px 16px !important;
/* above is a good size or uncomment the next line */
/* background-size: contain !important; */
}
To test this, go to the StackBlitz demo provided by the official documentation and paste the style.css file while having background changed to:
background: url('https://upload.wikimedia.org/wikipedia/commons/thumb/5/51/Mr._Smiley_Face.svg/414px-Mr._Smiley_Face.svg.png')
center center !important;

Answer 7

There isn't really a way to do this. Your best bet would probably be to use a third-party or custom Infowindow.

Answer 8

To replace with (or whatever image you might like), after
infowindow.open(map, marker);
you can try to add these lines
$('img[src="http://maps.gstatic.com/intl/en_us/mapfiles/iw_close.gif"]').each(function() {
$(this).attr('width', 14);
$(this).attr('height', 13);
$(this).css({width: '14px',height: '13px'});
$(this).attr('src','http://www.google.com/intl/en_us/mapfiles/close.gif');
});
