一、浮动
left 元素向左浮动
right 元素向右浮动
none 元素不浮动
inherit 从父级继承浮动属性
#fd{
width: 100px;
height: 100px;
background-color: red;
float: left;
}
#sd{
width: 100px;
height: 100px;
background-color: blue;
float: left;
}
#td{
width: 100px;
height: 100px;
background-color: green;
float: left;
}
#container{
width: 400px;
height: 500px;
background-color: darkgray;
}

二、clear属性
去掉浮动属性（包括继承来的属性）
left、right 去掉元素向左、向右浮动
both 左右两侧均去掉浮动
inherit 从父级继承来clear的值
