Question

我希望在主要部分，1个列表组，1个Twitter时间线和1个Facebook时间线中放置3列。

当全屏显示时，我希望所有3个在同一条线上，当它们不能将它们全部放在同一条线上时，我希望它们全部一个在页面中间的另一个下方（居中）（移动方案）。

在我的情况下，它们开始重叠，最后，当页面缩小时，它们会相互吼叫，但它们会留在左侧，并在右侧留下一些空白。

这是我的代码：

有什么建议吗？

谢谢！

Answer 1

只需将这些类添加到您的父div，它就会自动调整所有屏幕中心的iframe和列表项。

使用 col-sm-4 col-xs-12文本中心取消 col ，它会将您的网格变为一个低于另一个并且居中对齐但 text-center 会将内容对齐到所有设备的中心。

如果您想仅针对移动设备调整中心内容，则可以使用 css媒体查询和css属性 text-align：center; 用于小型设备。

您还可以在调整窗口宽度时使用jquery添加类文本中心

Jquery代码

$(window).resize(function(){
    if($(window).width() <= width_where_you_want_to_add_class){
       $('selector id or class').addClass('text-center');
    }    
});

Answer 2

您可以通过将col-xs-offset-2 col-xs-8 col-md-offset-0 col-md-4添加到3个部分来获得所需的布局。

为了获得更好的输出，请看一下这个小提琴。您可以随意调整其大小，并查看您的部分如何更改布局。 https://jsfiddle.net/qsy0nong/1/
