是否可以使用 Bootstrap 3 网格 CSS 来拥有跨越行和列的更大的嵌套单元格?

不需要bootstrap。您只需要使用 grid-area 设置一个单元格。更多信息请点击这里 https://developer.mozilla.org/en-US/docs/Web/CSS/grid-area

.grid {
display: grid;
grid-template-columns: repeat(6, 1fr);
grid-template-rows: repeat(4, 1fr);
grid-column-gap: 5px;
grid-row-gap: 5px;
min-height: 300px;
}

.grid > div {
background: #ccc;
}

.grid > div.my-big-sell {    
grid-area: 2 / 2 / 4 / 6;
background: #000;
}
<div class="grid">
