Bootstrap's .pull-leftand .pull-right, work using css-float.
Bootstrap 的.pull-leftand .pull-right，使用 css-float 工作。
The way float works is by flowing following inline elements around the floated element.
浮动的工作方式是跟随内联元素围绕浮动元素流动。
css-float support: left, right, none. There is no center option. Therefore, there is no .pull-center.
css-float 支持：left, right, none. 没有中心选项。因此，没有.pull-center.
You can align all inline elements within a block element by applying the css: text-align: centerto the parent.
您可以通过将 css:text-align: center应用于父元素来对齐块元素中的所有内联元素。
If the element is you're trying to center should be inline AND block-like, you should set it to have display: inline-block.
如果您想要居中的元素应该是内联和块状的，您应该将其设置为具有display: inline-block.
You can see some text-alignment options in bootstrap here:
http://getbootstrap.com/css/#type-alignmentNote that the <p>is a block-type element, and the text within has an implicit text-node which is display: inline.
您可以在此处的引导程序中看到一些文本对齐选项：http:
//getbootstrap.com/css/#type-alignment请注意，这<p>是一个块类型元素，其中的文本具有一个隐式文本节点，即display: inline.
