我有两个单选按钮和两张地图。我想在每张地图下方显示每个单选按钮。地图应该并排显示。我试过但没有成功。单选按钮出现在不相关的位置。请你帮助我好吗 ?

                var mapOptions = {
                    zoom: 10,
                    center: fenway,

                var map= new google.maps.Map(document.getElementById("map_canvas"),mapOptions);
              var map2= new google.maps.Map(document.getElementById("map_canvas2"),mapOptions);
            }

    <body onload="initialize()">
      <form >
        <div class="left-div" id="map_canvas" style="width: 500px; height: 500px;"></div>
        <input type="radio" name="A" id="choice1" value="c1" >A:
        <label for="choice1" >
        </label><br>
     <label for="choice2" >
          <input type="radio" name="B" id="choice2" value="c2" >B:
          <div class="right-div" id="map_canvas2" style="width: 500px; height: 500px;"></div>
        </label><br>
    </form>
这是CSS
.left-div {
    float: left;
    margin-right: 8px;
}
.right-div {
    margin-left: 508px;
}
