background image position fixed to parent element

由 ♀尐吖头ヾ 提交于 2019-12-23 10:54:38
问题 I have a div somewhere on the page and I need to give it a background image that does not move when you scroll your browser window. This is my code so far: #mydiv { float:left; width:540px; margin:40px 0px 0px 20px; background:url(/images/myimage.jpg) no-repeat fixed 0px 0px transparent; } The problem is that my background image is positioned relative to canvas and I need it to be positioned relative to #mydiv and still not scroll. To illustrate the problem please see here http://jsfiddle.net

Fixed DIV next to 5 fluid DIVs

问题 I require a fairly complex layout. I've been trying for a few hours to figure this out but still no luck. I require a fixed div next to 5 fluid DIVs. All the fluid DIVs need to be different percentages, but all 6 DIVs combined (1 fixed + 5 fluid) must equal to the width of the parent DIV. The height of the parent div will be fixed. Here's what I want: http://i.imgur.com/u0L6hrz.png But here's what I have right now: http://jsfiddle.net/mnNzR/ I need to eliminate the whitespace so all the DIVs

Fixed position element inheriting width of flex item

由 喜欢而已 提交于 2019-12-22 08:59:36
问题 I'm building out a UI that requires a fixed position/sticky element at the bottom of the viewport with a width constrained by a main content area. The main content area is optionally flanked by (sibling) left and/or right sidebars with fixed widths, so I'm using Flexbox to build the three column structure with flex-grow: 1 on the main content. I've learned from @Marc Audet's accepted answer at How can I make a fixed positioned div inherit width of parent? that setting width: inherit on the

Java fixed memory map

由 生来就可爱ヽ(ⅴ＜●) 提交于 2019-12-22 02:20:55
问题 Is there a simple, efficient Map implementation that allows a limit on the memory to be used by the map. My use case is that I want to allocate dynamically most of the memory available at the time of its creation but I don't want OutOFMemoryError at any time in future. Basically, I want to use this map as a cache, but but I wanna avoid heavy cache implementations like EHCache . My need is simple (at most an LRU algorithm) I should further clarify that objects in my cache are char[] or similar

What are the implications of using unsafe code

由 独自空忆成欢 提交于 2019-12-22 01:24:24
问题 Aside from the fact that the code itself can access memory directly. What are the other implications of using the "/unsafe" compiler flag and the "fixed" keyword? Are there any knock on effects related to code signing and deployment of my .exe (my app is desktop only)? (This isn't about whether or not I should be doing this, the why is covered in my question here) 回答1: Unsafe code is not verifiable, so you have to be aware of that. In a Full Trust environment, that's not a big deal, but if

CSS垂直居中和水平居中

由 China☆狼群 提交于 2019-12-21 09:24:59
前言 CSS居中一直是一个比较敏感的话题，为了以后开发的方便，楼主觉得确实需要总结一下了，总的来说，居中问题分为垂直居中和水平居中，实际上水平居中是很简单的，但垂直居中的方式和方法就千奇百怪了。 内联元素居中方案 水平居中设置： 行内元素 设置 text-align:center； Flex布局 设置display:flex;justify- content:center ;(灵活运用) 垂直居中设置： 父元素高度确定的单行文本（内联元素） 设置 height = line-height； 父元素高度确定的多行文本（内联元素） a:插入 table （插入方法和水平居中一样），然后设置 vertical-align:middle； b:先设置 display:table-cell 再设置 vertical-align:middle； 块级元素居中方案 水平居中设置： 定宽块状元素 设置 左右 margin 值为 auto； 不定宽块状元素 a:在元素外加入 table 标签（完整的，包括 table、tbody、tr、td），该元素写在 td 内，然后设置 margin 的值为 auto； b:给该元素设置 displa:inine 方法； c:父元素设置 position:relative 和 left:50%，子元素设置 position:relative 和 left:50%

问题 position:fixed that doesn't work for Internet explorer 6. I can't really understand the fixes found on google. I need it to work in IE6, IE7, IE8 & FireFox 3.0. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"> <head> <meta http-equiv="Content-type" content="text/html; charset=iso-8859-1" /> <title>Sidebar fixed</title> <style type="text/css"> #wrapper {

解决IE6不支持position:fixed问题

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 很少的时候，界面上需要一个固定位置的块，不论页面怎么滚动，始终停在它的位置，比如“返回顶部”、“给建议”、“分享按钮”、“广告”等等。css中有position: fixed;可以直接用，很方便，但是万恶的IE6却不支持，下面讲两种方法解决这个问题。 方法一： *html {/* 只有IE6支持 */ background-image: url(about:blank); /* 使用空背景 */ background-attachment: fixed; /* 固定背景 */ } #box { /* 非IE6浏览器使用固定元素 */ position: fixed; top: 0; left: 0; /* IE6改为绝对定位，并通过css表达式根据滚动位置更改top的值 */ _position: absolute; _top: expression(eval(document.documentElement.scrollTop)); } 这个方法要注意的是，*html使用固定位置空背景目的是解决滚动的时候抖动的问题，原理是这样，滚动页面浏览器重新计算出网页，然后执行css，所以固定元素产生延迟的抖动，使用固定背景之后，在滚动的时候先执行了css，再重新计算网页，所以没有抖动问题了。 document
