标签:alt cond ora padding style 效果 使用 onload count()
思路:先写出简单的数字计时,根据时分秒的数值转换成度数,使用CSS3的transform进行div倾斜。
知识点:transform可以对div进行倾斜或旋转等效果。但是根据浏览器不同代码也不同,本代码只能根据chorme浏览器或safari使用
div
{
transform:rotate(7deg);
-ms-transform:rotate(7deg); 	/* IE 9 */
-moz-transform:rotate(7deg); 	/* Firefox */
-webkit-transform:rotate(7deg); /* Safari 和 Chrome */
-o-transform:rotate(7deg); 	/* Opera */
}
