Question

我目前正在尝试按照Leaflet页上的分步说明操作，如何设置基本地图，但对我来说不起作用，该地图根本没有显示。我下载了Leaflet稳定版，并将所有这些文件放在一个文件夹中，并在其中创建了index.html文件。

这是我到目前为止的代码，

This is the HTML file

    <!DOCTYPE html>
    <html>
    <head>

    <link rel="stylesheet" href="leaflet.css" />
    <script src="leaflet.js"></script>

///The above part comes from the download page from Leaflet.com. They say that if you download the files, the code above is what you should put in the head section///

    </head>
    <body>


    <div id="mapid"></div>


    </body>
    </html>

这是.css。文件。说明说，我必须在.css文件中添加此“ #mapid {height：180px;}”。我是否可以像这样简单地复制它？

传单随附的原始.css文件。

/* required styles */

.leaflet-pane,
.leaflet-tile,
.leaflet-marker-icon,
.leaflet-marker-shadow,
.leaflet-tile-container,
.leaflet-pane > svg,
.leaflet-pane > canvas,
.leaflet-zoom-box,
.leaflet-image-layer,
.leaflet-layer {
    position: absolute;
    left: 0;
    top: 0;
    }

我的.css文件具有#mapid {高度：180像素； }代码

/* required styles */

#mapid { height: 180px; }

.leaflet-pane,
.leaflet-tile,
.leaflet-marker-icon,
.leaflet-marker-shadow,
.leaflet-tile-container,
.leaflet-pane > svg,
.leaflet-pane > canvas,
.leaflet-zoom-box,
.leaflet-image-layer,
.leaflet-layer {
    position: absolute;
    left: 0;
    top: 0;
    }

我在做什么错了？

我正在尝试通过他们的教程设置Leaflet地图，但是某些方法无法正常工作，任何人都可以看看为什么吗？
