Php 如何将openlayers映射精确地放入自定义div标记中？

我不熟悉web映射，并尝试使用一些代码将openlayers映射包含到div中，其中包括来自php的openlayers代码。它将显示div，但地图将沿着地图向下移动。如何更正我的代码？php包含在map div中

        <?php  include_once("gps_track.php") ;  ?>


        #map{
            clear:both;
            float:left;

            width:70%;

        }

我应该为css使用openlayes中的额外div吗

    var lat=27.6167
    var lon=85.5500
    var zoom=13

    var map;

    function init() {

js代码是：

你的问题我不太清楚，你没有展示初始化OpenLayers的javascript代码。如果使用var map=new OpenLayers.map'map'；初始化OpenLayers；，id映射为的div将被映射填充。因此，您应该只使用CSS来设置保存映射的div的正确大小，并且映射将具有相同的大小。如果这不是你问题的答案，也许你可以添加一个jsfiddle jsfiddle.net来澄清你的问题。我现在已经附加了openlayers代码，并保存在.php中。当我在索引页上加载函数init时，它运行良好，并在我的map div中进行了调整。但是这些问题中的错误原因是什么，以便我将来会注意到。我看不到您在哪里调用init函数。如果您想说清楚，请将您的代码放在jsfiddle.net中，并在关于这个问题的新评论中发布您的小提琴的url。
