通过阅读和学习书籍《CSS3实战》总结
《CSS3实战》/成林著.—北京机械工业出版社2011.5
多列布局适合纯文字版式设计，如报纸内和杂志类网页布局，不适合做网页结构布局。灵活使用多列布局特性，可以实现在多列中显示文字和图片，从而节省大量的网页空间。如果网页上的文字很长，多列布局特性就能够发挥它的用武之地。

columns属性–定义多列布局
columns是多列布局特性的基本属性，类似边框特性中的border属性，该属性可以同时定义多列的数目和每列的宽度。基本语法如下：
columns ： <column-width> || <column-count>
取值简单说明：
<column-width>:定义每列的宽度。<column-count>:定义列数。
column-width属性：定义列宽度
column-count属性：定义列数
column-width:<length> | auto column-count:<integer> | auto
取值简单说明：
auto：根据浏览器计算值自动设置。
column-gap属性–定义列间距
column-gap：normal | <length>
取值简单说明：
normal：根据浏览器默认设置进行解析，一般为1em。
column-rule属性–定义列边框样式
column-rule：<length> | <style> | <color> | <transparent>
取值简单说明：
column-span属性–定义跨列显示
column-span：1 | all
取值简单说明：
1：只在本栏中显示。
all：将横跨所有列，并定位在列的Z轴之上。
column-fill属性–定义栏目高度
column-fill ： auto | balance
简单取值说明：
auto：各列的高度随其内容的变化而自动变化。
balance：各列的高度将会根据内容最多的那一列的高度进行统一。

HTML代码：
<body><h1 id="故都的秋-选段">故都的秋（选段）</h1><h2 id="郁达夫">郁达夫</h2><p> 秋天，无论在什么地方的秋天，总是好的；可是啊，北国的秋，却特别 地来得清，来得静，来得悲凉。我的不远千里，要从杭州赶上青岛，更要从青岛赶上北平来的理由，也不过想饱尝一尝这"秋"，这故都的秋味。 </p><p>江南，秋当然也是有的；但草木雕得慢，空气来得润，天的颜色显得淡，并且又时常多雨而少风；一个人夹在苏州上海杭州，或厦门香港广州的市民中间，浑沌沌地过去，只能感到一点点清凉，秋的味，秋的色，秋的意境与姿态，总看不饱，尝不透，赏玩不到十足。秋并不是名花，也并不是美酒，那一种半开，半醉的状态，在领略秋的过程上，是不合适的。 </p><p>不逢北国之秋，已将近十余年了。在南方每年到了秋天，总要想起陶然亭的芦花，钓鱼台的柳影，西山的虫唱，玉泉的夜月，潭柘寺的钟声。在北平即使不出门去罢，就是在皇城人海之中，租人家一椽破屋来住着，早晨起来，泡一碗浓茶，向院子一坐，你也能看到很高很高的碧绿的天色，听得到青天下驯鸽的飞声。从槐树叶底，朝东细数着一丝一丝漏下来的日光，或在破壁腰中，静对着像喇叭似的牵牛花（朝荣）的蓝朵，自然而然地也能够感觉到十分的秋意。说到了牵牛花，我以为以蓝色或白色者为佳，紫黑色次之，淡红色最下。最好，还要在牵牛花底，教长着几根疏疏落落的尖细且长的秋草，使作陪衬。 </p><p> 北国的槐树，也是一种能使人联想起秋来的点缀。象花而又不是花的那一种落蕊，早晨起来，会铺得满地。脚踏上去，声音也没有，气味也没有，只能感出一点点极微细极柔软的触觉。扫街的在树影下一阵扫后，灰土上留下来的一条条扫帚的丝纹，看起来既觉得细腻，又觉得清闲，潜意识下并且还觉得有点儿落寞，古人所说的梧桐一叶而天下知秋的遥想，大约也就在这些深沉的地方。 </p><p>秋蝉的衰弱的残声，更是北国的特产；因为北平处处全长着树，屋子又低，所以无论在什么地方，都听得见它的啼唱。在南方是非要上郊外或山上去才听得到的。这秋蝉的嘶叫，在北平和蟋蟀耗子一样，简直像是家家户户都养在家里的家虫。 </p><p> 还有秋雨哩，北方的秋雨，她似乎比南方的下得奇，下得有味，下得更像样。 </p></body>
