Question

如何在线上的最后一个元素中删除（仅限CSS）填充？如果使用out＆＃34; no-gutters＆＃34;：https://www.codeply.com/go/p5kwypnNAw 是否有可能制作纯粹的css美容网格？

您可以在那里看到没有排水沟的示例： https://www.codeply.com/go/SM8kOTGbM5 主容器有黄色背景，因此您可以在最右侧元素上看到附加填充。

Answer 1

编辑：您的案例中的解决方案是将mr-2类的所有实例替换为mx-1。

mr-2表示：＆＃34;保证金权利2单位＆＃34;。 mx-1表示：＆＃34; 1个单位水平边距（两边）＆＃34;。

Answer 2

删除填充：只需尝试此类P * -0（* - x，y，l，r）

x- Xaxis

y- yasis

l-左

r - 右

例如：我要删除右边的填充

HTML：

<div class="pr-0">
----
----
----
</div>

或通过css：

div:last-child {
padding-right:0px;
}

将div替换为各自的班级
