您可以使用justify-content在内容之前和之后添加其他列，而不是1fr将内容置于中心位置。
然后将div之后的div和.line置于第二列的开头。
* {
box-sizing: border-box;
}
.outer {
width: 80%;
margin: 0 auto;
}
.wrapper {
border: 2px solid #f76707;
border-radius: 5px;
background-color: #fff4e6;
display: grid;
grid-template-columns: 1fr repeat(3, auto) 1fr;
}
.wrapper>div:not(.line) {
border: 2px solid #ffa94d;
border-radius: 5px;
background-color: #ffd8a8;
padding: 1em;
color: #d9480f;
}
.wrapper > div:first-of-type,
.line + div {
grid-column: 2;
}
.line {
grid-column: 1 / -1;
height: 1px;
background: black;
}

这是一个响应式解决方案，它可以处理variable个项目，并且无需添加愚蠢的硬编码div。基本上每个项目下面都有一行，复杂的部分是确定最后一行中不能有一行的项目。该示例使用flex-box(和LESS)，但是此处不相关，它也适用于grid。
.grid {
display: flex;
}
.grid-item{
position: relative;
.one-col{
flex-basis: 100%/1;
&:nth-last-child(1){
&:after{ border-bottom: 0; }
}
}
.two-cols{
flex-basis: 100%/2;
&:nth-last-child(1),
&:nth-last-child(2):nth-child(odd){
&:after{ border-bottom: 0; }
}
}
.three-cols{
flex-basis: 100%/3;
&:nth-last-child(1),
&:nth-last-child(2):nth-child(3n+1),
&:nth-last-child(2):nth-child(3n+2),
&:nth-last-child(3):nth-child(3n+1){
&:after{ border-bottom: 0; }
}
}
.four-cols{
flex-basis: 100%/4;
&:nth-last-child(1),
&:nth-last-child(2):nth-child(4n+1),
&:nth-last-child(2):nth-child(4n+2),
&:nth-last-child(2):nth-child(4n+3),
&:nth-last-child(3):nth-child(4n+1),
&:nth-last-child(3):nth-child(4n+2),
&:nth-last-child(4):nth-child(4n+1){
&:after{ border-bottom: 0; }
}
}
@media screen and (max-width: @screen__sm) {
.grid-item .one-col;
}
@media screen and (min-width: @screen__sm) and (max-width: (@screen__md - 1)) {
.grid-item .two-cols;
}
@media screen and (min-width: @screen__md) and (max-width: (@screen__lg - 1)) {
.grid-item .three-cols;
}
@media screen and (min-width: @screen__lg) {
.grid-item .four-cols;
}
&:after{
content: "";
display: block;
position: absolute;
left: 0;
right: 0;
bottom: 0;
border-bottom: solid 1px black;
}

我使用nth-of-type并将该行切换为其他类型()取得了一些成功。
我还为行跨越添加了第一和第六列，
而其他项只占据第2-5列。
