有人知道为什么我的滑块在头上而不是在身体上吗？

Question

我不知道为什么我的滑块在顶部而不是底部。我尝试过更改标题的宽度和高度，但这似乎并没有改变错误。见图：

这是我的CSS代码：

Answer 1

如果您想要使您的标题在页面底部:只需将top: 0替换为bottom: 0，它将出现在底部。

为什么？因为您使用绝对(固定)位置，它将使0从底部，而不是顶部。

nav {
   position: fixed;
   z-index: 10;
   left: 0;
   right: 0;
   bottom: 0;
   padding: 0 5%;
   height: 50px;
   background-color: #E94B3CFF;
}

或者您想要更改滑块的位置，只需将顶部更改为85%或更高。

.text {
   width: 40%;
   position: absolute;
   top: 85%;
   left: 2%;
   transform: translate(0%, -50%);
   color: #fff;
   opacity: 0.6;
   animation: text-left 5s linear infinite;
}
