position

问题 Following up on this post, I made a test, but I still got a bit of problem - the page has two scroll bars when you click to display the image. I don't need the background scrollbar when the image is being displayed, I only need the scrollbar on the image container. How can I hide the background scrollbar without making the page jumpy? the css, #container-image { position: fixed; top: 0; left: 0; width: 100%; height: 100%; overflow-x: auto; overflow-y: scroll; z-index:100; } the html, <p

问题 I got a little problem, I got a code, that reads all pixels and takes the RGB color of the pixel. But before that, I cut the picture into chunks, so I can also calculate larger images, without exceeding memory. Here is the code: Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED); try { decoder_image = BitmapRegionDecoder.newInstance(filePath, false); } catch (IOException e) { e.printStackTrace(); } try { boolean bool_pixel = true; final int width = decoder_image.getWidth(

问题 When converting my App, which has a SpriteKit scene in it, to iOS 10 I have had to convert my scene's original camera position from: cameraNode.position = CGPoint(x: self.size.width/2, y: self.size.height/2) to account for iOS10 with: if #available(iOS 10, *) { cameraNode.position = CGPoint(x: self.size.width/2, y: (self.size.height + voidSize)/2) } else { cameraNode.position = CGPoint(x: self.size.width/2, y: self.size.height/2) } The iOS10 version actually makes more sense as I do have part

问题 I have a series of images that makes a gallery-type of display. I use jQuery to make them round with a random diameter for each. It works perfectly fine, but then I need to place them correctly. The problem is that giving the <div> that contains the image a position:absolute (or any kind of position) turns the <div> back into a square. Is there a fix? Am I doing something wrong? I made a Fiddle to make the code clear. 回答1: Putting a wrapper <div> around each image, seems to solve it... http:/

问题 I have a scrollable div with a fixed height. While scrolling I need to get the element at the top of the visible viewport and the one at the bottom of the viewport. I can get the position of the scrollbar using scrollTop, however I am not sure how to get the element. Update: Formatted question for clarity. 回答1: Get your div's scroll position var scrollY = document.getElementById("yourDiv").scrollTop; Loop through the elements inside and look at their position var divs = document

问题 I am working on a website and I want to style an image like you style a background with background-position: center. Is there an equivalent to this for a regular image? Thanks in advance, Luuk EDIT: The image is responsive and contained in a container. CSS: .img-container { max-height: 300px; overflow: hidden; } .img-container img { max-height: 100%; max-width: 100%; } 回答1: I would do something like this to position the image centered. .img-container { display: flex; justify-content: center;

问题 I have a container div which has content that will sometimes need to be divided by class="top" and class="bottom" . Obviously there is no float:top or float:bottom , so what is the best way to achieve this with html/css alone? Ex: <div class="content"> <div class="left"> <a href="#"><img src="img/home.jpg" alt="salon home"></a> </div><!-- end left --> <div class="center"> <a href="#" class="top"><img src="img/about.jpg" alt="about salon"></a> <a href="#" class="bottom"><img src="img/services

问题 I am assuming I will need Javascript for this, but perhaps there is a CSS trick I'm not aware of. I have a web page based on a square background image. Ideally, the user would always set the browser as a square, but I know that won't happen. Because the image is square, if the image is set to fill the browser at 100%, the width is always the same as where the "bottom" of the page should be. Thus, to position an element dynamically horizontally (so the page can be resized but still hold it's

问题 I'm currently trying to make an object move towards another. I have this code so far to try and achieve it. double angleRad = Math.Atan2(mdlPosition.Z+treeTransform.Translation.Z, mdlPosition.X-treeTransform.Translation.X); enemyPos.X += (float)Math.Cos(angleRad) * 0.2f; enemyPos.Z += (float)Math.Sin(angleRad) * 0.2f; Whenever I move my player character, the object moves, but not towards the characters current position. How can I direct it towards current position? 回答1: Normally you should
