`位置：固定'在`< body>`有问题吗？ [英] Is `position: fixed` on `<body>` problematic?
问题描述
在移动设备和桌面浏览器的SPA上，我需要在< body> 上设置 position：fixed 以避免iOS溢出/橡皮筋滚动。
On a SPA for mobile devices and desktop browsers I need to set position: fixed on <body> to avoid iOS' overflow/rubberband scrolling.
位置：固定以及对< body>
position: fixed and modifications on the <body> are always somewhat hacky and risky to cause problems.
这就是为什么我想澄清：
This is why I wanted to clarify:
有任何已知问题/注意事项注意（即堆叠上下文，z索引上下文，静态/相对/绝对/固定定位在子项上）/ ...当添加 position：fixed 到< body>
Are there any known problems / caveats / things to watch out for (i.e. stacking context, z-indexing context, static/relative/absolute/fixed positioning on children) / ... when adding position: fixed to <body>
推荐答案
涉及相对于浏览器窗口定位的元素。网页浏览器缩放受其影响。
The "position: fixed" relates to an "element" positioned relative to the browser window. Webpage browser zooming is affected by it. IE6 and below will also break with it.
也许会更好：
html, body { height: 100%; overflow: auto; }
body .element { position:fixed; bottom: 0; }
然后对于html：
<body>
<div class="element">
(everything else inside here)
</div>
</body>
