Google Maps api v3 tools: visual distortions?

StackOverflow https://stackoverflow.com/questions/13962398

Question

I just noticed that the gMap view tools are displaying…rather unusually. Their regions still seem to be properly defined—I can interact with them just fine, it's just their appearance that looks messed up.

I haven't applied any CSS to any of the map pieces, and the only css I've applied to the map container is width:100%; height:100%; z-index:0; (which I normally do).

I do have other elements on the page which have position:absolute; and position:fixed; and some high z-indexs (500 & 1000). Is it possible they are causing the visual distortion of the Map's tools?

I see the same weird visual distortion in the latest versions of Chrome, Chrome Canary, Ffx, Safari, and Opera (on Mac OSX).

I checked dev tools / firebug, and no unexpected CSS is being applied to the map's container or directly to its tools.

Google Maps Api v3: Map interface tools

Here is the exact HTML (I stripped out the other elements and css and the weirdness still happens):

<html style="width:100%;height:100%;">
    <head>
        <link rel="stylesheet" href="shared/bootstrap/css/foundation.min.css">
        <link rel="stylesheet" href="shared/bootstrap/css/v2.2.2.min.css">
        <script
            type="text/javascript"
            src="http://maps.googleapis.com/maps/api/js?key=...">
        </script>
        <script type="text/javascript">
            function ginit() {
                var vancouver = new google.maps.LatLng(49.285415,-123.114982);
                var mapOptions = {
                    center: vancouver,
                    zoom: 15,
                    mapTypeId: google.maps.MapTypeId.ROADMAP
                };
                var map = new google.maps.Map(
                    document.getElementById("map"),
                    mapOptions
                );
                var infowindow = new google.maps.InfoWindow(),
                    marker;
            }//ginit()
        </script>
    </head>
    <body onload="ginit();" style="width:100%;height:100%;">
        <div id="map" style="width:100%;height:100%;"></div>
    </body>
</html>

EDIT: It appears the issue is coming from the combination of Foundation and Bootstrap: removing either one fixes the issue. Also it doesn't matter that no elements on the page reference classes from the libs, it causes the distortion all the same.

I tried to put this up in a fiddle, but I couldn't get jsfiddle.net to load.

Was it helpful?

Solution

For the future users who face same problem, here is the fix.

#map img{max-width: inherit;}

Like other answers said it is problem with max-width.

OTHER TIPS

Bootstrap and Foundation set { img max-width:100% } for Google Maps canvases. This causes the Maps controls to appear distored. Alter the css to be max-width:none;. [source]

Caveat: Apparently img { max-width: 100% … } is integral for images auto-resizes for responsive layouts, so use with caution. [source]

Foundation 5 no only breaks gmap, it also breaks MapQuest. Luckily both Goomap & Quest have class to allow us to overload F5 behavious only for maps display.

.google-map {
  height: 400px;  // no default height
  color: #191970; // default color for both text and background is white !!!
}

.quest-map {
  height:400px; 
  color: #191970;
}

// Fix Foundation bug with MapQuest
.mqa-display {
  img {max-width: none;}
  label { width: auto; display: inline; }
}

// Fix Foundation bug with GoogleMap
.gm-style {
  img { max-width: none; }
  label { width: auto; display: inline; }
}
