用css 设置页面居左，首先我们需要写好一个div然后设置好它的宽高，然后在使用margin来操作，使它距离浏览器的左边为0就行了，marign的用法如图：
添加一个border方便观察，具体看代码：
<html>
<head>
<style>
.div1{
width:600px;
height:200px;
font-size:13px;
border:1px solid #f00;
margin:0px;
}
</head>
<body>
<div class='div1'>
<p>我是测试文字</p>
</div>
</body>
</html>
/*------全局------*/
body,hr, p, blockquote, dl, dt, dd, ul, ol, li, pre, form, fieldset, legend, button, input, textarea, th, td,label{margin:0; padding:0;}
body{font:12px/1.5 tahoma, arial, \5b8b\4f53;}
h1, h2, h3, h4, h5, h6{ font-size:12px; font-weight:normal;}
ul, ol{list-style:none;}
a{ text-decoration:none;}
fieldset, img {border:none;}
.clear{ clear:both;}
