HTML基础

1. inline 标签的宽高设置
inline属性的标签有<span><a><strong>和<em>，Block标签包括< div><p><h1><form> 和<li>。由于内联标签的inline属性，无法设置高度，宽度，<span><a>< strong>和<em>可以通过加入display:block成为块元素来设置宽度和高度。2. 除水平滚动条
可以在body中插入overflow-x:hidden属性: body {overflow-x: hidden;}3. 在IE6中使用透明PNG图片
IE6的一个很难处理的BUG就是它不支持透明PNG图片，可以用CSS的滤镜来解决这个问题：
*html #image-style {
background-image: none;
filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src=”filename.png”, sizingMethod=”scale”);
