谷歌地图与页脚之间的小差距

Question

刚刚实现了谷歌地图到网站，但有一个很小的差距，可能是1-2px之间的地图和页脚。我想知道有没有办法让他们坐在一起，而不是有一个很小的差距。谢谢你的帮助或建议。不知道我怎么能解决这个问题！

Answer 1

只需加上

<style>iframe { display:block; } </style>

或

#maps {
    display: block;
}

在你的案子里。

iframe的默认显示属性是内联的。这意味着它们将放在文本基线上。你所看到的差距是文字行中字母的空格。因此，它与谷歌地图没有任何关系。

Answer 2

可能有一些或多个原因，比如在其他地方设置了填充和边距。

通过将margin-top设置为负值，您可以将页脚向上移动一点。

不过，请尝试添加以下内容：

#myFooter {
    background-color: #3d280c;
    color: white;
    padding-top: 30px;
    margin-top: -5px;
}
