如何使用Bootstrap在方形网格中指定分隔符的间隙

CSS grid-row-gap属性用于设置网格行元素之间的间隙大小。同样地，CSS grid-column-gap属性用于设置列元素之间的间隙（gutter）的大小。

语法:

CSS grid-column-gap属性

grid-column-gap: none|length|percentage|initial|inherit;

CSS grid-row-gap属性

grid-row-gap: length|percentage|global-values;

方法：它指定了网格线的大小。你可以把它看作是设置列/行之间的沟槽的宽度。

选择包括网格布局的类。
指定该类的grid-gap属性的值。
示例:

.container {
    grid-column-gap: <line-size>;
    grid-row-gap: <line-size>;
}

示例:

<!DOCTYPE html>
<html>
  
<head>
    <style>
        /*  Use grid-row-gap and grid-column-gap
            to specify the gap between the square
            grids the gap between the row is
            specified 10px the gap between the
            row is specified 100px */
        .grid-box {
            display: grid;
            grid-template-columns: auto auto auto auto;
  
            /* Specify the divider gap measurement in a grid */
            grid-row-gap: 10px;
            grid-column-gap: 100px;
            background-color: yellow;
            padding: 5px;
        }
  
        .grid-box div {
            background-color: pink;
            text-align: center;
            padding: 15px 0;
            font-size: 25px;
        }
    </style>
</head>
