问题一：如何实现浏览器兼容版的inline-block显示
display:inline-block;在ie6、ie7下只有设置在默认显示方式为inline的元素上才会生效，请实现兼容ie6、ie7的通用的方式。
使用display:inline-block属性:可以使行内元素或块元素能够变成行内块元素，简单直白点讲就是不加float属性就可以定义自身的宽、高，同时又能使该元素轻松在父元素居中显示！
如果是内联元素使用了inline-block，那所有的浏览器显示都是正常的。注：使用inline-block属性在IE下会触发layout，因此元素上设置的width、height是能生效的，所以也就有了同其它浏览器一致的显示效果 , 而不能说IE6/7支持 display:inline-block！
如果是块级元素使用了inline-block，那在ie6和ie7中是有问题的。ie6/ie7中块元素仅仅是被display:inline-block触发了layout，而它本身就是行布局，所以触发后，块元素依然还是行布局，而不会像火狐等其他浏览器块元素呈递为内联对象。
实际有效的方法共有2种：
div {display:inline-block;*display:inline; *zoom:1;...} ，如果先定义了 display:inline-block，然后再将 display 设回 inline 或 block，layout
不会消失）。代码如下（…为省略的其他属性内容）：
div {display:inline-block;...}div {*display:inline;} 问题二：实现一个自适应布局
已知HTML结构和效果图如下：
<div class="parent"> <div class="side">侧栏</div> <div class="main">主栏</div></body>
要求如效果图中标注，两栏间距为10px，请写出这个两列布局的CSS。
