z-index

问题 I am using PDFsharp to generate a PDF document from scratch. I am trying to write text on top of a gradient filled rectangle. After generating the document, the gradient appears on top of the text rendering the text completely hidden. using (var document = new PdfDocument()) { var page = document.AddPage(); var graphics = XGraphics.FromPdfPage(page, XGraphicsPdfPageOptions.Append); graphics.SmoothingMode = XSmoothingMode.HighQuality; var bounds = new XRect(graphics.PageOrigin, graphics

问题 OK guys, here's a tricky one (perhaps): is there any to get a sort of "global z-index" of an element? here is an example of what i'd like to do: given two element references, how would you determine which one is hiher in the z order (given that they may not have assigned z-indices or are in separated containers) Elaborate hacks welcome! Not-so elaborate methods more than welcome. 回答1: This was an interesting problem. The following code may not be bug free. I just put it together right now and

问题 I did setup an HTML page where I use z-index to set the elements "visual" order. It works as expected; but breaks when I use transform: scale() . #blocks-both{ transform: scale(0.9); } I make a simplified example here : http://codepen.io/anon/pen/LNYrar I read a lot of messages regarding this particular problem, but I can't find a solution to make my design work. I guess I don't understand something regarding this. Could someone help ? Thanks ! 回答1: This is a known issue: css z-index lost

问题 I'm trying to get a view to "slide behind" another view. Consider a set of cards as an example: if I put card A behind card B, card A is still there but it is being blocked because card B is OVER or IN-FRONT-OF card A. I am well aware of setInvisibilty() but that is not the effect I'm looking for. I have an animation that animates a Google-Now-card-like view onto the screen. The card passes over some text that is shown in front of the card (whereas I want the card to slide above the text)

问题 In a webpage I need to show a div layer over the flash banner which is not using wmode=transparent setting. How to solve it? 回答1: From what I remember you can shove the div into an <iframe> (perhaps using Javascript so you don't make a mess of your HTML). Iframes are window objects like flash so they're able to overlay each other. 来源： https://stackoverflow.com/questions/1470166/how-to-solve-zindex-issue-with-flash

问题 I'm creating a prototype of a CSS/XHTML tables-based calendar that eventually will be generated with PHP for the Simple Updates content management system. I've run into a problem with using absolute positioning to create a popup that would show all the events in a day when there are more than will fit in a cell. The problem can be seen here: http://sutest.bravehost.com/ As you can see, the popup pops under the multi-day event and date in both IE7 and IE6. Putting a z-index on the popup fixed

问题 The z-index style allows you to control what order boxes are painted in. For example, you can make a child element be painted below its parent element: #parent { background: rgba(33, 33, 33, 0.7); } #child { width: 100px; height: 100px; background: yellow; position: relative; z-index: -1; } <div id="parent"><div id="child"></div></div> However, when the parent element is the <body> tag, this no longer behaves as expected: body { background: rgba(33, 33, 33, 0.7); } #child { width: 100px;
