怎么使浮动自适应宽度 改变页面框大小的时候不会往下掉，用position：fixed会不会在不同的分辨率发生错位

<div class="clear"></div>

ccs ：.head-background{
width: 100%;
height: 93px;
background-image: url(../imgs/bulletbg.png);
background-repeat: repeat-x;
}
.logo{
float: left;
margin: 9px 30px;
}
.head-content{
margin: 0 auto;
width: 71%;
height: 100%;
}
.head-middle{
float: left;
margin-left: 3px;
width: 67.6%;
height: 90%;
background-image: url(../imgs/head-ico.png);
}
会下掉的地方在head-middle那里
