[float;drift]∶漂移
如：河心有条鱼向这边浮动 2 [be unsteady]∶非固定 如：浮动工资 1 飘浮移动；流动 宋林逋《山园小梅》诗之一：“疏影横斜水清浅，暗香浮动月黄昏 ”明高明《琵琶记·强就鸾凰》：“烛影摇红，帘幕瑞烟浮动 ”鲁迅《野草·好的故事》：“大红花和斑红花，都在水里面浮动 2 浮躁，不稳重 《北齐书·薛琡传》：“﹝ 薛琡 ﹞天性险忌，情义不笃，外似方格，内实浮动 ”《北史·恩幸传·徐纥》：“﹝ 徐纥 ﹞性浮动，慕权利，外似謇正，内实谄谀 ”蔡元培《工学互助团的大希望》：“因为他的言论，他的举动都质实得很，没有一点浮动与夸张的态度 ”3 动荡不稳定 张难先《日知会始末》：“适 长江 旱灾，人心浮动 ”茅盾《动摇》五：“大概只是小小的误会罢了，然而也可见人心浮动 ”4 不固定，上下波动 李先念《在中央工作会议上的讲话》五：“其他产品由企业根据市场的供求情况自行确定生产数量，允许自产自销，价格有的由国家规定，有的根据市场供求关系允许在一定幅度内浮动 ”5 车辇的一种装饰物 唐苏鹗《杜阳杂编》卷下：“公主乘七宝步辇，四面缀五色香囊……其上仍络以真珠玳瑁，又金丝为流苏，雕轻玉为浮动 ”什么是浮动浮动是css布局非常强大的布局功能，也是理解CSS布局的关键问题所在，在CSSW中，包括div在内的任何元素都可以浮动的方式显示 为什么要使用浮动浮动浮动浮动是一种非常有用的布局方式 它能够改变页面中对象的前后流动顺序 这样做的好处是，使得内容的排版变的简单，具有良好的伸缩性 举个例子，左右分栏的布局，左栏宽度为300px 如果使用一种相对的布局方式，我们可以使右栏显示在距左边300px的位置，这样可以使右栏贴着左栏进行显示 一旦涉及被改变，例如left的宽度由300px变为100px,就意味着right的定位需要重新设定，而使用浮动式布局方式后，当我们指定左栏的浮动为left，意味着其右方的内容将流入左栏的右边，而且能够根据左栏的宽度自动流入并贴进左栏，贴进的程度则靠左栏的右边距或者右栏的左边距来控制，二不依赖于对象本身的宽度值 浮动式布局使页面的大部分内容都可以由游览器自动调节，使我们能够专注于样式设计而非其相互之间的浮动关系，我们只需要简单地设置浮动方向，即可完成对象的布局分布
