实体化网格，在2列之间放置多余的空间

Question

我对CSS框架有点不满意，我试图做一些简单的事情：2列用于移动设备和平板电脑的大小不同，但是，这2列之间有一个烦人的空间，我无法理解正在发生。

如果您要谈论的是我在所附图像上用红色括号标记的间隙，则该间隙不是两列之间的间隙。我用蓝色背景色标记了您的第一列。

您的侧面导航具有300px的固定宽度，只是没有填充第一列。

materialize.min.css

.sidenav {
    position: fixed;
    width: 300px;
    left: 0;
    top: 0;
    margin: 0;
    -webkit-transform: translateX(-100%);
    transform: translateX(-100%);
    height: 100%;
    height: calc(100% + 60px);
    height: -moz-calc(100%);
    padding-bottom: 60px;
    background-color: #cf303000;
    z-index: 999;
    overflow-y: auto;
    will-change: transform;
    -webkit-backface-visibility: hidden;
    backface-visibility: hidden;
    -webkit-transform: translateX(-105%);
    transform: translateX(-105%);

}
