所有设备的引导列布局

我对bootstrap列布局有疑问。是否有必要为每个设备宽度指定列布局?例如,我想要一些项目细节,它将占据中心的一半屏幕。所以我使用类divcol-*-6创建了一个包装器col-*-offset-3(因此需要六列并将其偏移3列)。

然后,在这个元素中,我将有一些子项,它将占用3列,其中一列将使用9来填充容器的整个宽度。

<div class="col-md-6  col-md-offset-3 toppad">
   <table>
   <tr><td class="col-md-3">Project ID:</td><td class="col-md-9">{$project['name']}</td></tr> 
   </table>
</div>

这是对的吗?是否有可能使其适用于所有设备而无需对每个设备进行编码?

LubošSuk,你好。

你的主要问题(需要所有课程)......是的 如果您想控制在所有设备上查看的方式,则需要使用所有col-xx-xx类...
选择正确的单班,就像我在演示中为您展示的那样 如果您使用col-xs-xx而不是col-md-xx,这种方式也可以。

您只选择使用一个col-md-xx课程的红色和灰色块的选项将无法像您想要的那样工作,因为它们可以并排存在。

您会看到红色和灰色块仅使用您的col-md-xx,并且它们都松散到需要的位置。他们开始堆叠

将主要区块放在中间位置的方法是正确的......但...... 当您使用col-xx-offset-x并且您希望/需要div块在小型设备上全屏显示时,您必须在此视图中将此类归零。

演示中的第二个块显示何时可以控制偏移以获得全宽。

如果您想要更多地控制row 宽度,请查看此演示中的底部选项。

以下是 Fiddle
