Question

我有一些div，其中有一个小差距或空白。我尝试过更改上下边距，但是没有用。我认为它与图像有关，但我还没有找到解决方案。

Answer 1

html中有一个`字符，这会产生额外的空间。

Answer 2

你有一个`在这些div之间

用这个替换这些div

    <div id = "header-bg">
        <div id = "header-wrapper">

        </div>
    </div>

   <div class = "details-wrapper">

    </div>

Answer 3

从height删除#header-bg。您为高度设置了590px。

Answer 4

Poistioning和display：flex不能很好地结合在一起。

如果你想在flexed容器上使用position：absolute，在＃header-bg上应用position：absolute，那是因为你有空白
