这是FIDDLE。

为了改变图像，我使用了CSS动画。 现在我想做的是在图像改变时改变文本在图像上的颜色。

怎么做？ 非常感谢任何帮助。

谢谢！

您可以向h2发送另一个名为textFadeInOut

的动画 
@-webkit-keyframes textFadeInOut {   // add other browser prefixes too
     0% {
         color: green;
     }          
     100% {
         color: yellow;
     }
  }

将此动画添加到figure.effect-lexi h2

答案 1 :(得分：0)

以下是使用JQuery UI的简单解决方案：

为你的h2添加一个id：

<h2 id="yourText">Dark <span>Chocolate Smoothie</span></h2>

使用JQuery UI动画更改文本的颜色：

var timeOffset = 2500;
var changeTime = 2500;

function changeImage() {
    if (red) {
        $("#yourText").animate({
            "color": "#fff"
        }, changeTime, function () {
            setTimeout(function () {
                changeImage();
            }, timeOffset);
        });
    } else {
        $("#yourText").animate({
            "color": "#f00"
        }, changeTime, function () {
            setTimeout(function () {
                changeImage();
            }, timeOffset);
        });
    }
    red = !red;
}

setTimeout(function(){changeImage();}, timeOffset);

注意：设定时间并不完美，您可能需要进行一些实验才能找出正确的时间

答案 2 :(得分：-1)

使用css中的color属性

我在

添加了这一行 
figure.effect-lexi:hover h2, figure.effect-lexi:hover p {
    color: red;
    opacity: 1;
    -webkit-transform: translate3d(0, 0, 0);
    transform: translate3d(0, 0, 0);
}

Here is a demo
