background-image

问题 I just launched a website the other day and thought it was free of weird CSS mistakes, but apparently it's not. What I am trying to do here is stretching an image to fit the page in height and width. The problem: I have the following markup: <img src="images/night_sky7.jpg" class="stretch" /> and the following CSS applied to it: img.stretch { left: 0px; position: absolute; top: 0px; width: 100%; z-index: 0; } This is working fine on my 17.1' laptop with 1440x900 resolution, but I noticed it

问题 So prior to iOS 7.1 I was setting the background image in my app UINavigation Bar via UI Appearance like so. [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"image-name"] forBarMetrics:UIBarMetricsDefault]; It was working fine and the content was getting blurred properly when behind it. Now the content is not blurred at all the navigation bar is just transparent. If I remove the image and set just the navigation bar tintColor it will blur the content correctly. Anyone

问题 I am wanting to construct navigation items from three (background) images, with the first and last a fixed width, and the central a variable width, depending on the width of the text in the nav item. I have been led to believe that using the pseudo elements before and after would be the best method. When I try this though, the main (central) background image for the nav item is overlapping with the before and after background images. You can see what I mean on this page. Here is the CSS: .box

问题 I have a div that contains an image element set up as such: <div id="container"> <img src="cat.jpg"/> </div> And CSS: #container { width: 150px; height: 200px; } #container img { width: 200px; height: 200px; overflow: none; } Currently the container width is smaller then the img width meaning that right part of the image is cropped out which is what I want. However, I would like the left part of the image to be cut out instead. I've tried experimenting with background positioning but haven't

问题 Since I faced an issue with the background image beeing too short for the content at different resolutions, I tried to split the background into 3 parts and stretching the middle one automatically to fill the space between the top and bottom image accordingly. Unfortunately I didn't manage to realize this in CSS. How to do this exactly? content_background_top.png: 1024 x 68px content_background_middle.png: 1024 x 6px (Stretched) content_background_bottom.png: 1024 x 71px Something like this:

问题 I found this script to change the body's background image when you click a link. It works, great except the only problem is is that I cannot have a pre-defined bg image in the css or else it won't change. So I remove the css for the background image and it switches the images fine, but I want an image to be default to start with. Script: <script language="JavaScript"> <!-- var backImage = new Array(); // don't change this backImage[0] = "images/bg0.png"; backImage[1] = "images/bg1.png";
