使用 HTML 创建标记

您可以使用自定义 HTML 和 CSS 来创建具有丰富视觉效果的标记，这些标记具有交互功能和动画效果。所有 Marker3DElement 实例都会作为 HTML 元素添加到 DOM 中；您可以使用 Marker3DElement 属性访问这些元素，还能像操控任何其他 DOM 元素一样来操控它们。

CSS

@keyframes marker-bounce {
    0% {
        transform: translateY(0);
    }
    30% {
        transform: translateY(-12px);
    }
    55% {
        transform: translateY(-5px);
    }
    75% {
        transform: translateY(-10px);
    }
    100% {
        transform: translateY(-8px);
    }
}

简单的 HTML 标记

以下示例展示了如何创建基本的自定义标记：

<html>
<head>
    <title>3D Map - Declarative</title>
    <style>
        html,
        body {
            height: 100%;
            margin: 0;
            padding: 0;
        }
        gmp-map-3d {
            height: 100%;
        }
    </style>
</head>
<body>
    <gmp-map-3d center="37.4239163, -122.0947209, 0" tilt="67.5" range="1000" mode="hybrid">
        <gmp-marker-3d position="37.4239163, -122.0947209,50" altitude-mode="absolute" extruded="true" label="Basic Marker"></gmp-marker-3d>
    </gmp-map-3d>
    <script async
        src="https://maps.googleapis.com/maps/api/js?key=YOUR_KEY&v=beta&libraries=maps3d"></script>
</body>
</html>

交互式标记

此示例展示了如何使用 HTML 创建交互式标记。

<html>
  <head>
    <title>Pure HTML Interactive Marker Demo</title>
    <style>
      html,
      body {
        height:100%;
