CSS - position absolute & document flow

不羁的心 提交于 2019-12-01 08:18:01
Yes, I know doesn't work with position absolute, but is there a way to display elements "below" (after in code) not behind them? Example: <img src="image.jpg" style="width: 500px; height: 400px; position: absolute; top: 0;" /> <h2 style="padding: 15px" >This text is behind not below the image</h2> Is there a way of displaying the h2 below the image excepting positioning it absolutely too? Example: http://jsfiddle.net/fDGHU/1/ (yes, I have to use absolute in my case, and dynamic margined content below, and I'm lost :D) JCOC611 The only way I was able to do what you are asking is setting the top

详解css中position属性

最近画富瑞的界面,很多元素的定位都是个问题(在我没有很详细的知道position属性之前) 后来上网查了下关于position的一些相关的属性和用法,遂整理了一下 position:属性:固定元素的定位类型。即元素脱离文档的布局流,在元素的任意位置显示。 关于position的属性值,有四种: 1、static:默认布局(默认值) 2、fixed:固定定位,顾名思义是固定的意思,和absolute定位类似,但是比absolute更”定“!(不随滚动条的滚动而滚动) 3、relative:相对定位,脱离文档的布局流,但是会在文档的原先位置留下空白 4、absolute:绝对定位,脱离文档的布局流,在文档中不会留下位置 下面简答的说下这几种定位方式: 一、static 这个布局为默认的布局,所以可说可不说,大家都比较熟悉了 这就是意味元素没有被定位,而且在文档出现在它应该出现的位置上 二、fixed fixed定位的对象是以body为定位的对象,简而言之就是根据整个窗口(page)进行定位,通过(t,r,b,l)来进行定位, 如果你的scroll设置为false的话,这个定位就很吊了!,很多网站的广告就是这个鬼 其实感觉网上都说得很麻烦,在我的理解,fixed就是把这个元素钉死在屏幕的这个点上,别的都不管(简单粗暴) 三、absolute 绝对定位

项目用到的技术 transaction,过度动画 translate3d改变z坐标值,来实现图片切换 touchStart touchMove touchEnd 用到的基础知识 vertical-align 属性设置元素的垂直对齐方式(相对于父元素) display:table-cell实现大小不固定的图片在父元素中垂直居中的效果,但是需要注意ie67不支持 遇到的问题 在设置元素的height元素宽度是屏幕高度的时候,其dom结构是这样的body>div>ul>li>img,img中已经加载了一张宽度为457的图片.设置body的高度为100%,然后却发现未能生效,在这里需要设置body的position属性为absoulte才行,但是为什么,说的很模糊.这里需要复习一下relative,fixed和absolute的相关知识 fixed 设置absolute:fixed时,元素以top,left,bottom,right进行定位,而定位的参考对象就是body或者说是浏览器窗口.显而易见的,元素也就脱离了标准文档流 absolute:以最近的一个设置了position:absolute的祖先元素(不是父元素哦,也可能是爷爷,祖爷爷元素),如果没有这样的元素,那么就以body元素为参照.同样适用top等进行定位.同样也脱离了标准文档流 relative:举个例子吧

But i am always having trouble with catching the x and y when the webpage is using margins at the body, or other elements, absolute/relative elements, such like that. Is there a solution wich provides the exact position, no matter what margins or paddings are used. :) 回答1: I use following code to move div box to follow cursor in this Web IME site function xy(x) { o = document.getElementById(x

Django Get Absolute URL

I want to get absolute url in templates. I can't do with url. It gives me a relative URL. I need to get this: http://domain.tld/article/post but Django gives me just /article/post I played with settings.py but it didn't work. (debug=false, allowed hosts vs.) Template code: {% url 'blog:detail' blog.slug %} This is easy to do in a view. For example: from django.core.urlresolvers import reverse def Home(request): posts = Article.objects.filter(published=True).order_by('-publish') site = Site.objects.get_current() c = RequestContext(request, { 'posts': [{'post': post, 'url': request.build

Bash: retrieve absolute path given relative

我的梦境 提交于 2019-11-29 19:29:08
Is there a command to retrieve the absolute path given the relative path? For example I want $line to contain the absolute path of each file in dir ./etc/ find ./ -type f | while read line; do echo $line done use: find $(pwd)/ -type f to get all files or echo $(pwd)/$line to display full path (if relative path matters to) epere4 Try realpath . ~ $ sudo apt-get install realpath # may already be installed ~ $ realpath .bashrc /home/username/.bashrc To avoid expanding symlinks, use realpath -s . The answer comes from " bash/fish command to print absolute path to a file ". If you have the
