button按钮背景图及隐藏value的值
怎样写button按钮背景图才能让IE6显示？

.goods_buy_info .goods_buy_but .goods_buy_but {background: url(../images/goods20110309_25.gif);background-repeat: no-repeat;background-position: left top;border:0px;}

注意点就在background: url(../images/goods20110309_25.gif);
千万不能写成background-img: url(../images/goods20110309_25.gif);
怎样写css才能使button隐藏value值呢?

.goods_buy_info .goods_buy_but .goods_buy_but {float:left;/*或者float:left|right*/width:138px;height:39px;overflow:hidden;text-indent:-9999px;text-transform:capitalize;border:0px;}

注意点
1.float:left;/*或者float:left|right*/
2.高度与宽度
3.text-indent一定要足够大
4.最好加上text-transform:capitalize;
下面付上按钮代码：

<style>.goods_buy_but {float:left;/*或者float:left|right*/width:138px;height:39px;overflow:hidden;text-indent:-9999px;text-transform:capitalize;background: url(../images/goods20110309_25.gif);background-repeat: no-repeat;background-position: left top;border:0px;}</style><input name="" type="submit" value="提交"/>
