Is `position: fixed` on `<body>` problematic?

由 烂漫一生 提交于 2019-12-24 16:29:15
问题 On a SPA for mobile devices and desktop browsers I need to set position: fixed on <body> to avoid iOS' overflow/rubberband scrolling. position: fixed and modifications on the <body> are always somewhat hacky and risky to cause problems. This is why I wanted to clarify: 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> 回答1: The "position

问题 How do I make an absolutely positioned element go to the bottom of the page? I want to create a "cover" over my page. In order to make it cover the whole page, I used "position: absolute" with each of the four directions set to 0. However, when the height of the page content is greater than the height of the client window, the cover height is the client height, not the height of the full page. JS Bin <style> #a { width: 100px; height: 2000px; background: red; } #b { position: absolute; bottom

如何将div放置在其容器的底部？

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 鉴于以下HTML： <div id="container"> <!-- Other elements here --> <div id="copyright"> Copyright Foo web designs </div> </div> 我希望 #copyright 坚持 #container 的底部。 不使用绝对定位就可以实现吗？ 如果float属性支持'bottom'值，那似乎可以解决问题，但不幸的是，事实并非如此。 #1楼 另外，如果有使用 position:absolute; 的规定 position:absolute; 或 position:relative; ，您总是可以尝试 padding 父 div 或放置 margin-top:x; 。 在大多数情况下，这不是一个很好的方法，但在某些情况下可能会派上用场。 #2楼 CSS中没有什么叫做 float:bottom 东西。 最好的方法是在以下情况下使用定位： position:absolute; bottom:0; #3楼 Div样式， position:absolute;bottom:5px;width:100%; 正在工作，但是需要更多向上滚动的情况。 window.onscroll = function() { var v =

1. html:标签 2.CSS： position background text-align margin padding font-size z-index overflow hover opacity float(clear:both) line-height border color display 页面布局： 后台管理布局： position: 　　fixed 　　relative 　　absolute 1. .left{ float:left; 因为float经常用，所以可以给它写一个样式，然后在下面直接应用这个样式就可以了。 2. 父亲定义了高度/宽度以后，里面的div才可以用%的形式来定义高度/宽度，定义的时候是以父亲div为标准的。现在的问题就卡在怎么样设置高度上了。是猜一下页面高度呢，还是设置100%呢（实际上无效）。 <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <style> body{ margin:0; } .pg-header{ height:48px; background-color:#2459a2; color:white; } .pg-content .menu{ width:20%; background-color

问题 I'm trying to automate JPEGmini which is not entirely scriptable - the only way to control it is via the "Open" dialog. Repeatedly calling it once per image is extremely slow. Instead I'm trying to to perform a search for .jpg or .jpeg files in the "Open" dialog, so that within that result set I can select the batch of files I want to process and open them in a single pass. (More detail after the code example) -- later within the search results list I get, I want to select these set

问题 I am facing a problem with my singleton when used across multiple class loaders. E.g Singleton accessed by multiple EJBs. Is there any way to create a singleton which has only one instance across all class loader? I am looking for pure java solution either using custom class loader or some other way. 回答1: The only way would be to make your singleton class be loaded by a single classloader - put that jar file in the bootclasspath, for example. A static variable is inherently tied to the

-webkit-overflow-scrolling breaks absolute positioning

问题 I am building a page that needs to have some elements which stick to the top of the page when they would otherwise be scrolled off the screen. I managed to do this using position:absolute . Everything was working perfectly, but it needed momentum scrolling. I added -webkit-overflow-scrolling: touch to the css of the scrollable area. This broke everything. My sticky elements with position:absolute are now just scrolling with the rest of the content. My question is this: Why does -webkit
