浏览器默认样式

1.页边距
IE默认为10px，通过body的margin属性设置
FF默认为8px，通过body的padding属性设置
要清除页边距一定要清除这两个属性值

复制代码

代码如下:

body {
margin:0;
padding:0;
}

2.段间距
IE默认为19px，通过p的margin-top属性设置
FF默认为1.12em，通过p的margin-bottom属性设
p默认为块状显示，要清除段间距，一般可以设置

复制代码

代码如下:

p {
margin-top:0;
margin-bottom:0;
}

3.标题样式
h1~h6默认加粗显示：font-weight:bold;。
默认大小请参上表
还有是这样的写的

复制代码

代码如下:

h1 {font-size:xx-large;}
h2 {font-size:x-large;}
h3 {font-size:large;}
h4 {font-size:medium;}
h5 {font-size:small;}
h6 {font-size:x-small;}

个大浏览器默认字体大小为16px，即等于medium，h1~h6元素默认以块状显示字体显示为粗体，
要清除标题样式，一般可以设置
