我正在尝试为个人网站制作带有一些文字的简介动画。 如何添加这样的文本简介:https://codepen.io/nathanlong/pen/MyYqNd 在此CSS动画上:https://codepen.io/gvrban/pen/rzNGpW
我试图复制/粘贴并合并两支笔,但是不起作用
我希望文本出现在动画上
这是动画的代码

我已将两个密码笔合并为一个。
我只是改变了班级
.intro {
position: absolute;
top: 0;
right: 0;
left: 0;
bottom: 0;
width: 100%;
height: 100%;
background-color: black;
}
到
.intro {
position: absolute;
top: 0;
right: 0;
left: 0;
bottom: 0;
width: 100%;
height: 100%;
background-color: transparent;
z-index: 2;
}
使用绝对位置时,z-index
用于使对象/元素彼此重叠(想象一个分层结构)。具有最高z-index
的元素将显示在所有位置设置为绝对值的元素的顶部。
Here是有关z-index的更多信息。
看看this。希望这是理想的输出。
