我有一个矩阵背景的东西功能齐全，但我只想让我的标题随滚动一起移动，每次我将.content部分更改为不同的位置时它会完全取消矩阵（矩阵实际上并不是一个背景，它更像是一个背后的区域。

你的问题有点难以理解，请原谅我，如果这不是你想要的，但这里有一个小提琴，你可以看到如何修改你的标题到顶部/左边，以防止它滚动内容：
.header {
height: 200px;
width: 100%;
background: red;
position: fixed;
top: 0;
left: 0;
}
.content {
height: 1000px;
margin-top: 200px;
background: green;
}
答案 1 :(得分：1)
我不确定你在这里究竟是什么意思，但是如果你想要的是在滚动页面顶部停留的固定标题，那么你应该试试这个。
.header {
height:50px;
background:#000;
border:1px solid #0F0;
width:960px;
position: fixed;
margin-left: auto;
margin-right: auto;
left: 0;
right: 0;
top:0;
}
在codepen上测试它保持固定并在滚动页面顶部居中。
