I have this CSS3 code:

#box2 {
    position: relative;
    width: 500px;
    border: 1px solid black;
    box-shadow: -3px 8px 34px #808080;
    border-radius: 20px;
    box-shadow: -8px 5px 5px #888888;
    right: 300px;
    top: 113px;
    text-align: justify;
    -webkit-transition: all 1s;
    font-size: large;
    color: Black;
    padding: 10px;
    background: #D0D0D0;
    opacity: 0;
}


@-webkit-keyframes mySecond {
    0% {
        right: 300px;
        top: 13px;
        background: #D0D0D0;
        opacity: 0;
    }

    100% {
        background: #909090;
        right: 300px;
        top: 63px;
        opacity: 1;

.littlebox2sentence {
    font-size: large;
    padding-bottom: 15px;
    padding-top: 15px;
    padding-left: 25px;
    padding-right: 10px;
    background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#9CCEDA), to(#58A8D8));
    border-top-right-radius: 10px;
    border-bottom-right-radius: 10px;

    -webkit-transition-duration: .25s, .25s;
    -webkit-transition-timing-function: linear, ease-in-out;
    color: #164ad7;

我如何做渐变色的动画?如果颜色是例如蓝色和红色的它工作正常(背景颜色过渡),但是当我用渐变色代替它,它不工作。我发现了一些教程,但他们并不真正帮助了我。

How can I do an animation with gradient color? If the colors were for example blue and red it works fine (the background color transition) but when I replace it with gradient color it doesn't work. I found some tutorials but they don't really helped me.

推荐答案

在使用渐变作为背景,你不定义背景色。渐变是一个背景图像。
背景图像是不是可以得到动画的属性。所以,你的做法是行不通的。

When using a gradient as background, you don't define a background-color. A gradient is a background-image. Background-image isn't a property that can get animated. So your approach can not work.
