position: fixed with background image?

问题 When I add the <!DOCTYPE HTML> on the page I am finding that I have to add position: fixed; into the CSS in order for the image to show up as the background on the "div" otherwise I get a blank, white background. Why does this require that position = fixed in this case? .background_image{ position: fixed; <-----Why is this needed & Why doesn't static work? background: #000 url(../Images/Image.jpg) center center; width: 100%; height: 100%; min-height:100%; background-size: cover; overflow:

问题 I use the BackgroundMediaPlayer for my App to play Audio in the Background. Now i see these buttons: How can i activate them? 回答1: In order to make the media controls from the taskbar to work, you need to load and configure the SystemMediaTransportControls from the foreground application AND the background task. If you are doing it only from the background task, the controls will be displayed but they will remain disabled. In your foreground application, you should have the following code:

How can I smoothly transition CSS background images?

问题 The main solution out there is: "Just throw a loading screen up until the page is loaded". But my goal is to build pages that present the basics very quickly, without a loading screen, and then transition in the images and fancy features when they're ready. So I'll wait till it's loaded, and then fade it in. Or I'll load in a very low res version and then fade in the high res when it's ready. The one aspect of this practice that I have not yet figured out is how to do it with background

Have a transparent background in a plot exported from Octave

问题 I am using portable Octave 5.1.0 under Win 10. I mean to write a plot to png with transparent background. Disclaimer: This question is similar to the two linked below. I opted asking the present different question since I am adding further relevant information (by the same token, question #2 below was not a dupe of #1). This is what I found: print(gcf,'-dpngalpha', 'myplot.png'); , suggested in Saving a plot in Octave with transparent background, does not work for me. It is remarkable that I

Check if window is in background Tkinter

由 ≡放荡痞女 提交于 2021-02-05 09:20:10
问题 So, I'm trying to make an app on tkinter . I've just started learning how this module works. In my app, I have a root window and a child (top leveled) window, and I set the child to be always on top. When I minimize my root window, the child window also minimizes, because I have defined that condition. My problem is when I select other window. When I do it, the child window still stays on top and I want to know if there is a way to know if my root window is in background, a.k.a.: I'm not

问题 Speaking of mobile devices, whats the difference between those two methods? If I press the home key both are called. Is there any situation when one is called and not the other? 回答1: Since this UnityAnswer is one of the first (if not the first) to be returned on a search for OnApplicationFocus/Pause & iOS, an important update in Unity 4.6.1 has changed the behavior for iOS. As of 4.6.1, both OnApplicationFocus and OnApplicationPause will be called in iOS. The order is : App initially starts:
