Sud*_*han 5 css linear-gradients css3 css-transitions css-animations
我正在使用CSS3开发日出和日落动画,请检查运行时jsFiddle输出.
正如预期的那样,太阳从一种颜色转变为另一种颜色





问题在于Sky从一种模式转换到另一种模式,颜色变化是突然的并且不是线性的

请检查JsFiddle代码(带注释).
有什么我想念的吗?如果有人可以给我一些参考或任何指示,我会感激不尽.
我要做的是将整个渐变,从头到尾应用到单个元素上(对于我的例子,我将使用#sky),然后设置该元素的位置动画,使其看起来像颜色渐渐变淡.Twitter的Bootstrap使用这个技巧来动画按钮悬停的背景.
使用这种方法查看我的JSFiddle的分支:http://jsfiddle.net/jakebellacera/6Zabx/
这是我添加的CSS:
#sky {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 900%; /* This must be in a factor of three */
background-image: -webkit-linear-gradient(top, rgba(30,152,209,1) 0%, rgb(202, 229, 243) 11%, rgba(125, 185, 232, 0.82) 22%,
rgb(240, 231, 26) 33%, rgb(245, 86, 12) 44%, rgba(197, 127, 81, 0.82) 55%,
rgba(5, 5, 5, 1) 66%, rgb(54, 55, 56) 77%, rgb(3, 3, 3) 100%);
background-image: -moz-linear-gradient(top, rgba(30,152,209,1) 0%, rgb(202, 229, 243) 11%, rgba(125, 185, 232, 0.82) 22%,
