grid 网格布局详解

网格布局主要的 9 个属性

属性 参考值 定义解释
display grid 声明为 grid 盒子
grid-template-columns/rows 列数/行数 划网格定义例/行数,repeat(重复次数,重复值)
gird-auto-flow column/row 默认行优先,定义交叉轴/主轴方向上排列
grid-auto-rows/columns 宽高大小 定义隐藏网格的宽高,应用场景在项目数量大于网格数量时
grid-area 行列 格式:开始行/开始列/结束行(可 span 指定)/结束列(可 span 指定),用于网格合并操作,span 指定跨越的网格数
gap 行列间距 格式顺序:行间距 列间距,间距相等时可省略一个
place-content start,end,center 父盒子的剩余空间在子盒子中的分配方式,计算好父盒子与子盒子大小(加上 gap)之后,一般用不到
place-items start,end,center 项目在网格中的分布方式,一般采用 center,居中显示
place-self start,end,center 控制单个项目的在网格中的分布方式
