CSS3中新出现的多列布局(multi-column)是传统HTML网页中块状布局模式的有力扩充。这种新语法能够让WEB开发人员轻松的让文本呈现多列显示。我们知道，当一行文字太长时，读者读起来就比较费劲，有可能读错行或读串行；人们的视点从文本的一端移到另一端、然后换到下一行的行首，如果眼球移动浮动过大，他们的注意力就会减退，容易读不下去。所以，为了最大效率的使用大屏幕显示器，页面设计中需要限制文本的宽度，让文本按多列呈现，就像报纸上的新闻排版一样。
属性 描述
column-count 指定元素应该被分割的列数。
column-fill 指定如何填充列
column-gap 指定列与列之间的间隙
column-rule 所有 column-rule-* 属性的简写
column-rule-color 指定两列间边框的颜色
column-rule-style 指定两列间边框的样式
column-rule-width 指定两列间边框的厚度
column-span 指定元素要跨越多少列
column-width 指定列的宽度
columns 设置 column-width 和 column-count 的简写
列布局的浏览器完美兼容
对于一些不支持多列布局特征的浏览器，比如IE9/IE8，会把这些属性全部忽略，这样布局就呈现出传统的单块布局。
为了保证浏览器最大的兼容性，我们在使用多列布局属性时，最好添加浏览器引擎前缀，最基本的要加上三种：谷歌浏览器的-webkit-，火狐浏览器的-moz-，IE浏览器的-ms-，最后，别忘了不带前缀的写法。

<p>This module describes multi-column layout in CSS. By using functionality described in this document, style sheets can declare that the content of an element is to be laid out in multiple columns. </p>
<p>On the Web, tables have also been used to describe multi-column layouts. The main benefit of using CSS-based columns is flexibility; content can flow from one column to another, and the number of columns can vary depending on the size of the viewport. Removing presentation table markup from documents allows them to more easily be presented on various output devices including speech synthesizers and small mobile devices.</p>

据俄罗斯《消息报》19日报道称，俄罗斯空军的2架苏-35战斗机近日抵达位于莫斯科近郊的葛罗莫夫试飞院。
根据消息，这2架苏-35将用于中国飞行员在俄进行的苏-35飞行培训。俄方曾表示，首批4架苏-35将于年底前交付中国，
预计届时在俄罗斯完成培训的中国飞行员将直接驾机回国，而且很可能回国就能形成战斗力。
