fixed

移动端业务开发，iOS 下经常会有 fixed 元素和输入框(input 元素)同时存在的情况。 但是 fixed 元素在有软键盘唤起的情况下，会出现许多莫名其妙的问题。 这篇文章里就提供一个简单的有输入框情况下的 fixed 布局方 http://efe.baidu.com/blog/mobile-fixed-layout/?qq-pf-to=pcqq.group 来源： oschina 链接： https://my.oschina.net/u/270331/blog/601524

I have a collection of fixed width files with a varying number of columns and field sizes. The top of the file starts with a line like: AAAAABBCCCCCCCCCCDDD and so on The change in character denotes the end of one field and the start of another. I am guessing this can someone be used to work out what the field sizes are with code and then apply the same values to the actual data lines below. I then want to output all the read data into a XLS file or even a DataGrid, but my issue is I have no idea how to code this. Any help would be greatly appreciated :) /Edit: I implemented Cuong's solution

Having some issues getting this to work. PLEEEEEEASE help. I would like an element fixed to the top of the viewport, when the user scrolls down the page it remains at the top of the viewport... easy. If the window is narrower then 960px the horizontal scrollbars appear. If the window is scrolled horizontally I would like the content inside this fixed element to scroll with it. Please check out the demo, the two green boxes should always line up. Make your window narrow and scroll horiz, notice how they no longer line up. Is this possible without JavaScript? Should work in IE7+ and not totally

Is there a way a fixed positioned div can inherit the width of a parent? I know fixed width is relative to the window's so this code doesn't work: #wrapper{ position: relative; width:500px; height: 20px; background-color: blue; } #header{ position: fixed; width: 100%; height: 20px; background-color: rgba(255,0,0,0.5); } <div id="wrapper"> #wrapper <div id="header"> #header </div> </div> Use the inherit value for the width property on the #header selector. Why This Works By specifying position: fixed to the #header element, the #header element's position is calculated with respect to the

I have a site with a fixed header and slide-out sidebars. With iOS7 in portrait orientation, the fixed header stays fixed when the sidebar is visible, but on iOS8 the header pushes slightly upward depending on how far down you are scrolled. I need it to stay fixed. See this jsbin: http://jsbin.com/xuyevi/2/ The main pieces are a header, a sidebar, and the main content. The header is fixed to the top of the screen using fixed position and has a z-index that keeps it above the content when you are scrolling. The sidebar is fixed to the left side of the screen, and is initially hidden by being

今日帮同事解决一个问题，发现元素为fixed固定，当父元素滚动时，这个设置了fixed元素居然不会固定在浏览器上，而是跟着滚动了，后来查了一下才知道。原来当fixed元素的父元素有transform属性时，fixed会降级为absolute。 鑫大神总结的非常好： http://www.zhangxinxu.com/wordpress/2015/05/css3-transform-affect/ 来源： oschina 链接： https://my.oschina.net/u/3757195/blog/3134569

I am doing a iPhone app using Phonegap & also using jquery mobile. I want to set background image for data-role=page div. In this height of page is equal to screen & hence background is set to size of screen. But the page content length is much greater than screen & hence gray background is seen after image completes. My question is whether there is a way so that we can keep the background image fixed & scroll or move only content of page & not background image. Just to mention I have tried full size background jquery pluggin . Its working on Android but not on iOS. Can anyone please help?
