Question

我正在使用animate.css为页面加载时的文本设置动画。我正在推迟效果，但它正在显示文本然后动画它看到了吗？

Answer 1

看看你的CSS，我认为这些是我们正在讨论的两个要素：

.imagetextbig { 
    position: absolute; 
    top: 240px; 
    width: 100%;
    color: goldenrod;
    font-size: 90px;
    text-align: center;
    animation: slideInLeft 1s;
    animation-delay: 0.9s;
}
.imgtext2{
    margin-top: 100px;
    animation: slideInRight 1s;
    animation-delay: 0.9s;
}

如果您希望首先隐藏它们然后从页面两侧滑入，则有两种选择。第一个选项是更改CSS，以便它们在屏幕外启动并在屏幕上显示动画。但是，没有一个即插即用的解决方案，您可以直接使用animate.css动画并使其正常工作。

所以我们可以做第二个选项，即在页面加载时隐藏它们，然后在动画开始时显示它们。在页面首次加载时，使用元素的默认样式中的visibility: hidden隐藏它们。

.imagetextbig { 
    position: absolute; 
    top: 240px; 
    width: 100%;
    color: goldenrod;
    font-size: 90px;
    text-align: center;
    animation: slideInLeft 1s;
    animation-delay: 0.9s;
    visibility: hidden; /*add this*/
}
.imgtext2{
    margin-top: 100px;
    animation: slideInRight 1s;
    animation-delay: 0.9s;
    visibility: hidden; /*add this*/
}

然后，在动画中，我们要确保切换到visibility: visible，否则您将为不可见元素设置动画。

如果我们转到animate.css website并查看其源代码，我们可以看到slideInLeft的动画如下所示：

@keyframes slideInLeft {
    0% {
        transform: translate3d(-100%,0,0);
        visibility: visible;
    }

    to {
        transform: translateZ(0);
    }
}

换句话说，在动画开始时将元素设置为可见已经为您完成了。因此，只需在开始时将visibility: hidden添加到默认样式即可。 slideInRight动画类似于slideInLeft动画：它还在开始时设置visibility: visible。所以没有什么可担心的。
