Position Fixed Not Working for Header
提问by Andrew
I am trying to create a very simple effect where the navigation sticks to the top of the page as you scroll down the page. All I should have to do is set "position: fixed" to the header, which I currently have. For some reason, it's treating it more like a "position: absolute" element vs. fixed. I tried it on other elements on the page with the same effect, so I must have something that in my HTML or CSS code that is causing the issue. Any ideas?
我正在尝试创建一个非常简单的效果，当您向下滚动页面时，导航会固定在页面顶部。我所要做的就是将“位置：固定”设置为我目前拥有的标题。出于某种原因，它更像是“位置：绝对”元素与固定元素。我在页面上的其他元素上尝试过，效果相同，所以我的 HTML 或 CSS 代码中必须有导致问题的内容。有任何想法吗？

Header CSS
标题 CSS
.nav-main {overflow: visible; position: fixed;
top: 0; left: 0; right: 0; height: 60px; width: 100%;}
Note, the site is responsive, so the position: fixedkicks in at 768px.
请注意，该站点是响应式的，因此position: fixed在 768 像素处启动。

At the moment, Chrome cannot render position:fixedon elements under a transformation. Delete the (content-free)
目前，Chrome 无法position:fixed在转换下的元素上呈现。删除（无内容）
-webkit-transform: translate3d(0, 0, 0);
and it will work.
它会起作用。
