Google Maps API v3: Custom styles for infowindow

Question

I\'ve tried many of the examples from the google maps reference and from other stackoverflow questions, but I haven\'t been able to get custom styles on my infowindow.

Answer 1

You can style the infoWindow by styling the .gm-style-iw class.

  #map-canvas {
    .gm-style {
      > div:first-child > div + div > div:last-child > div > div {
        &:first-child > div,
        &:first-child > div > div > div,
        &:last-child,
        &:last-child > img {
          display: none !important;
        }
      }
      .gm-style-iw {
        top: 20px !important;
        left: 130px !important;
        background: #fff;
        padding: 10px;
        height: 40px;
      }
    }
  }

How about using the Infobox plugin rather than using the usual Infowindow? I put up a complete example in a jsfiddle example here. The main thing about the infobox is that you can create your infobox within your page's html, giving you complete control over how it looks using css (and some javascript options, if necessary). Here's the html for the infobox:

<div class="infobox-wrapper">
    <div id="infobox1">
        Infobox is very easy to customize because, well, it's your code
    </div>
</div>

The idea here is the "infobox-wrapper" div will be hidden (i.e., display:none in your css) and then in your javascript you will initialize an Infobox object and give it a reference to your "infobox" (inside the hidden wrapper) like so:

infobox = new InfoBox({
    content: document.getElementById("infobox1"),
    disableAutoPan: false,
    maxWidth: 150,
    pixelOffset: new google.maps.Size(-140, 0),
    zIndex: null,
    boxStyle: {
                background: "url('http://google-maps-utility-library-v3.googlecode.com/svn/trunk/infobox/examples/tipbox.gif') no-repeat",
                opacity: 0.75,
                width: "280px"
        },
    closeBoxMargin: "12px 4px 2px 2px",
    closeBoxURL: "http://www.google.com/intl/en_us/mapfiles/close.gif",
    infoBoxClearance: new google.maps.Size(1, 1)
});

This is just an example of some of the available options. The only required key is content - the reference to the infobox.

And to open the info window:

google.maps.event.addListener(marker, 'click', function() {
    infobox.open(map, this);
    map.panTo(loc);
});

And to further demonstrate the flexibility of the InfoBox, this jsfiddle has an image with a css transition as the "info box".

And one final tip: Don't use the class "infobox" in your html. It is rather unfortunately used by the plugin when the infobox is actually generated.

Answer 3

If you can't use infobox and need to customise the infowindow you can access it using css. It's not pretty, relies heavily on first:child/last:child psuedo selectors and obviously on whether google ever decides to change their map html structure.

Hopefully the below css can help someone else out in a bind when they're forced to deal with infowindow.

/* white background and box outline */
.gm-style > div:first-child > div + div > div:last-child > div > div:first-child > div
{
    /* we have to use !important because we are overwritng inline styles */
    background-color: transparent !important;
    box-shadow: none !important;
    width: auto !important;
    height: auto !important;
}

/* arrow colour */
.gm-style > div:first-child > div + div > div:last-child > div > div:first-child > div > div > div
{
    background-color: #003366 !important; 
}

/* close button */
.gm-style > div:first-child > div + div > div:last-child > div > div:last-child
{
    margin-right: 5px;
    margin-top: 5px;
}

/* image icon inside close button */
.gm-style > div:first-child > div + div > div:last-child > div > div:last-child > img
{
    display: none;
}

/* positioning of infowindow */
.gm-style-iw
{
    top: 22px !important;
    left: 22px !important;
}

I wanted to have a transparent contact form popup on google map marker click. I made it finally with the help of infobox plugin and this post. That's what I made.

Anyone can download and use the source from here
