Question

我正在使用1140网格系统，并且有一个基本问题：如果你想要一个小于12个宽的元素，你是否需要使用空div作为“间隔符”？

这是我想要实现的模型：

基本上，我想要只在主要区域下面，但在它自己的行中。我能看到这样做的唯一方法是使用div作为“spacer”来将页脚缩进到我想要的位置。这是怎么做到的？

这有点像在表格布局中使用间隔gif吗？

是的，基本上div会创建你想要的空间。使用CSS网格框架时，通常使用具有相应列类的空div，以便相应地分隔内容。当然，你可以提出涉及相对定位等的替代解决方案，但为什么会让事情变得复杂。最后一段代码看起来应该是这样的。

    <footer class="row twelvecol">
        <div class="threecol first"></div>           
        <div class="threecol bottom">A</div>
        <div class="threecol bottom">B</div>
        <div class="threecol bottom last">C</div>
    </footer>
