网格模板列 - 项目不在中心

Question

我正在尝试使用“grid-template-columns”创建我自己的网格，结果是当我调整视图项目时未居中。

我使用这个文档https://developer.mozilla.org/en-US/docs/Web/CSS/grid-template-columns

我被困住了，需要一些建议，我做错了什么。

P.S 在普通桌面视图中看起来不错，但在移动设备中... 下面我附上了截图和我的代码示例。

这里是我正在使用的代码示例：

Answer 2

justify-items 沿行（内联）轴对齐网格项目。具体来说，此属性允许您在特定位置为网格容器（而非网格本身）内的项目设置对齐方式。
