HTML5 Canvas camera/viewport - how to actually do it?

阅读更多关于 HTML5 Canvas camera/viewport - how to actually do it?

I'm sure this was solven 1000 times before: I got a canvas in the size of 960*560 and a room in the size of 5000*3000 of which always only 960*560 should be drawn, depending on where the player is. The player should be always in the middle, but when near to borders - then the best view should be calculated). The player can move entirely free with WASD or the arrow keys. And all objects should move themselves - instead of that i move everything else but the player to create the illusion that the player moves. I now found those two quesitons: HTML5 - Creating a viewport for canvas works, but

Mobile overflow:scroll and overflow-scrolling: touch // prevent viewport “bounce”

阅读更多关于 Mobile overflow:scroll and overflow-scrolling: touch // prevent viewport “bounce”

问题 On a mobile (safari, webviews, wherever), overflow:scroll and overflow-scrolling: touch give a pretty smooth scroll, wich is cool. But, it makes the page "bounce" (area circled below), which is not the case when you are not using it, but which makes the experience a little less "native" (and more simply, as far as I can have an opinion about it, is absolutely unuseful) Is there a way to prevent it to happen ? Thanks a lot for your help/hints/replies 回答1: I've managed to find a CSS workaround

Check if element is between 30% and 60% of the viewport

阅读更多关于 Check if element is between 30% and 60% of the viewport

I am trying to change the color of <li> elements when they are between 30% and 60% of the viewport. So I have this grid of elements stacking side by side like this: I ran into few plugins like Waypoints, Viewport Checker and few others but nothing good. Any idea? I am using a pretty simple structure : JSFIDDLE HTML <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <title></title> <meta name="description" content=""> <meta name="author" content=""> <link rel="stylesheet" href="css/reset.css"> <link rel="stylesheet" href="css/styles.css"> <script src="http://code.jquery.com/jquery
