嵌入的google地图未显示我在地图中可供选择的图层

Question

I have a share: https://drive.google.com/open?id=1pPt91pmN97vXiq2bNUAJ-CXXqus&usp=sharing This works wonderful if you are signed into google. I would like the same to occur when not signed in. When I use the Embed this map:

<iframe src="https://www.google.com/maps/d/embed?mid=1pPt91pmN97vXiq2bNUAJ-CXXqus" width="640" height="480"></iframe>

I get only the map title and nothing else works. I want them to be able to check the places I have categorized.
They aren't even showing up.

Answer 1

add in your css for iframe: display:block; I know that is strange but it work

as I have

html code:
<div class="flexible-container">
<iframe src="https://www.google.com/maps/d/embed?mid=1mEwMw6znzNq_kMcG7xmkqfuPDrI" frameborder="0" allowfullscreen></iframe>
</div>

css code:
.flexible-container{
    position:relative;
    float:left;
    width:855px;
    height:480px;
    padding:7px 0 20px 0;
    background:#4d6a79;
    box-shadow: 1px 2px 3px 0px rgba(0,0,0,0.80), 0px -1px 1px #fff;
    border-radius:7px;
}
.flexible-container iframe{
    width:855px;
    height:480px;
    border:0;
    display: block;
    }
