Question

我设计了带有左侧导航的页面，该页面在全屏上看起来不错，但是，当我将其调整为移动尺寸时，我的主要内容停留在一列中，并且没有填满整个视口-留下了相当大的空白在左边。

我相信媒体查询中的某些原因可能会导致这种情况。

让我知道您是否可以看到它和CSS：

Answer 1

您的#main-doc有margin-left: 310px;。在您关于(max-width: 815px)的媒体查询中删除此内容，就可以了！

Answer 2

在 @media only屏幕的＃main-doc 中添加左边距：0; ，并且（最大宽度：815px） 宽度媒体查询如下

左边缘反射：310px；＃main-doc即使在内容的移动宽度处也向右移动。

@media only screen and (max-width: 815px)
#main-doc {
    position: relative;
    margin-left: 0;    /* *** add this *** */
    margin-top: 270px;
}

添加后，您的网站在移动设备宽度上将如下所示
