transitions

问题 I'm really struggling trying to create smooth CSS transitions in Safari. I'm trying to hide/show divs by changing their height with a JavaScript onclick event. The resulting transitions are nice and smooth with Chrome, Firefox, and Edge. However with Safari it just looks bad and must be around 15 fps when rendering. A basic JSFiddle is here: https://jsfiddle.net/q5a9b62s/6/ The website I'm working on is here: http://www.allinimages.ch/ Thanks. 回答1: You could try using JavaScript to add a

问题 I'm pushing ViewControllers on NavigationController by segues. I have my own subclassed NavigationController which has inserted UIImageView at index 0 - it's a background for my entire application. The problem is that I can see that when new view controller is coming to the screen from the right side, in the beginning it's like having some light dark overlay which is disappearing when just after viewDidApear is called. Every view controller has a self.view.backgroundColor = [UIColor

问题 I'm making a graph with interactive markers. Each marker begins along the side axis, and when clicked moves to its place along the line and grows in size. I got the icons to move and grow, but am having trouble resetting the graph. I can make the icons go back to their original location with a second click, but the icons won't respond to anymore clicks after they've been clicked a second time. I suspect it's something simple, but I'm not seeing it. var coal = svg.append("svg:image") .attr(

问题 In Webkit, the following fiddle works as expected. That is to say, #navigation's left padding is transitioned properly from 0 to 100px. In Firefox, the identical code somehow prevents the transition from occuring. http://jsfiddle.net/threehz/JEMN6/27/ my css: #navigation { background: #ccc; -webkit-transition: padding-left 0.125s ease; -moz-transition: padding-left 0.125s ease; transition: padding-left 0.125s ease; margin: 0; padding-left: 0; width: 100%; } .fixed #navigation { padding-left:

问题 What I'm trying to do... I'm toying with D3 to make a compound animation. I have the following final state: Essentially I want to animation connecting the dots - add the first circle . Then draw the line to the second circle. Once the line is drawn, the second circle is added. To add some visual appeal, I perform other transitions, such as changing circle radius for the first and second circle as the line is draw. What I've tried... I can add the circles and draw the line individually,

问题 This works great: <style type="text/css"> div { width:100px; height:100px; background:red; transition:width 2s; -moz-transition:width 2s; /* Firefox 4 */ -webkit-transition:width 2s; /* Safari and Chrome */ -o-transition:width 2s; /* Opera */ } div:hover { width:300px; } </style> But does anyone know of a way to do this using click instead of hover? And not involving JQuery? Thanks! 回答1: You can write like this: CSS input{display:none} .ani { width:100px; height:100px; background:red;

问题 In Objective-C, using Sprite-Kit, I would successfully use something like the following code in Objective-C to bring up a new scene if ([touchedNode.name isEqual: @"Game Button"]) { SKTransition *reveal = [SKTransition revealWithDirection:SKTransitionDirectionDown duration:1.0]; GameScene *newGameScene = [[GameScene alloc] initWithSize: self.size]; // Optionally, insert code to configure the new scene. newGameScene.scaleMode = SKSceneScaleModeAspectFill; [self.scene.view presentScene:

问题 I have an UITabBarController, when initial run, I want to overlay a login view controller but received error. Unbalanced calls to begin/end appearance transitions for < UITabBarController: 0x863ae00 >. Below is the code. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; //

问题 I'm developing my own website, and one of the 'features' it has is that when I go with my mouse over the header, it slides down. This works well and good on all major browsers. However, with IE 10, it doesn't. Here's the page source: <?php echo "<html> <head> <title>memodesigns</title> <link rel='stylesheet' href='style/stylesheet.css'> </head> <body>"; include_once('modules/header.php'); echo " </body> </html>"; ?> This is the header file which is included: <?php echo "<div id =

问题 I have an example animated line chart located here: http://www.animatedcreations.net/d3/animatedLineChart.html Everything is working as I would like it to, except that the redraw on the graph line is not smooth as in the example at the bottom of this page: http://bost.ocks.org/mike/path/. Another problem is that the line and x axis are slightly out of sync. I am pretty sure the problem with code lies in how .attr("d", line) is updated. Any help would be very much appreciated - I've been stuck
