Question

我正在制作地图应用程序，我希望谷歌地图DIV填充标题下方的剩余高度。代码如下。

  <!DOCTYPE html>
  <head>
    <title>Map Application</title>

    <style type="text/css">
    html {
        height: 100%;
    }
    body {
        height: 100%;
        margin: 0;
        padding: 0;
    }
    #map_canvas {
        margin: 0;
        padding: 0;
        height: 95%;
        width: 100%;
    }
    @media (max-width: 767px) {
        #start_lat, #start_lng, #dest_lat{
          margin-bottom: 0.5em;
      }
  }
</style>

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

我尝试过绝对定位，但似乎Google Map覆盖了相对定位，请提供建议。

谢谢。

Answer 1

你可以给<nav>一个固定的高度，并使用calc（）来计算#map_canvas的高度：

.navbar {
    height:150px;
}

#map_canvas {
    height:calc(100vh - 150px);
}

否则你可以使用flexbox：

body {
    display:flex;
    flex-direction:column;
    min-height:100vh;
}

.navbar {
    flex-grow:0;
}

#map_canvas {
    flex-grow:1;
}

Answer 2

试试这个：

#map_canvas {
position: absolute;
top: 0px;
}

尝试为#map_canvas提供绝对位置和顶部：0px。这应该做。
