CSS3 多列屬性
CSS3中新出現的多列佈局(multi-column)是傳統HTML網頁中塊狀佈局模式的強大擴充。這種新語法能夠讓WEB開發人員輕鬆的讓文字呈現多列顯示。我們知道，當一行文字太長時，讀者讀起來就比較費勁，有可能讀錯行或讀串行；人們的視點從文本的一端移到另一端、然後換到下一行的行首，如果眼球移動浮動過大，他們的注意力就會減退，容易讀不下去。所以，為了最大效率的使用大螢幕顯示器，頁面設計中需要限製文字的寬度，讓文字以多列呈現，就像報紙上的新聞排版一樣。
屬性 #描述上
# #column-count ##說明
# # 列數指定列數指定的列數。
column-fill 指定如何填入列
column-gap 指定列與列之間的間隙
column-rule 指定列與列之間的間隙
column-rule 所有column-rule-
column-rule * 物件的簡寫
column-rule-color 指定兩列間邊框的顏色
column-rule-style 指定兩列間邊框的樣式
column-rule-##column-rule-## width 指定兩列間邊框的厚度 column-span 指定元素要跨越多少列
#column-width count 的簡寫
列佈局的瀏覽器完美相容對於一些不支援多列佈局特徵的瀏覽器，例如IE9/IE8，會把這些屬性全部忽略，這樣佈局就呈現傳統的單塊佈局。 為了確保瀏覽器最大的相容性，我們在使用多列佈局屬性時，最好添加瀏覽器引擎前綴，最基本的要加上三種：Google瀏覽器的-webkit-，火狐瀏覽器的-moz-，IE瀏覽器的-ms-，最後，別忘了不帶前綴的寫法。 <!DOCTYPE html>

<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。
