Get actual pixel coordinates of div after CSS3 transform

由 有些话、适合烂在心里 提交于 2019-12-30 01:44:04
问题 Is it possible to get the four actual corner coordinates of a <div /> that has been transformed with CSS3 attributes like scale , skew and rotate ? Example: Before the CSS3 transformation the coordinates are x1y1: 0,0 x1y2: 0,200 x2y1: 200,0 x2yw: 200,200 and the div looks like this: after a little bit of CSS3 magic transform: skew(10deg, 30deg) rotate(30deg) scale(1, 2); it looks like this: How can I get the coordinates (with javascript) of the actual corners (not the bounding box)? Any help

CSS vh units inside an iframe

由 喜夏-厌秋 提交于 2019-12-30 01:37:30
问题 I'm trying to use CSS vh units inside of an iframe. I'm finding that they are scaled to the size of the iframe somehow. In other words, 100vh isn't the windowheight. It's set to the height of the iframe. Does this seem right? Is there a workaround? 回答1: I know this is an old question, but as people move toward the vh unit, this question will become much more common. To clarify, here's an example of the problem. We have an HTML file that loads an iframe : <!DOCTYPE html> <html> <head></head>

Set a CSS3 transition to none

由 ╄→гoц情女王★ 提交于 2019-12-30 00:14:44
问题 How would I make it so a CSS transition doesn't work inside a media-query, or in any other case? For example: @media (min-width: 200px) { element { transition: width 1s; } } @media (min-width: 600px) { element { transition: none; // SET TO NO TRANSITION } } 回答1: You can set the transition-property to none . This way, no transition effect will be applied. Like this: -webkit-transition-property: none; -moz-transition-property: none; -o-transition-property: none; transition-property: none; 回答2:

CSS RGBA border / background alpha double

由 北城以北 提交于 2019-12-29 19:51:04
问题 I'm working on a website that has a lot of transparency involved, and I thought I would try to build it entirely in RGBA and then do fallbacks for IE. I need a "facebox" style border effect, where the outer border is rounded and is less opaque than the background of the box it surrounds. The last example from http://24ways.org/2009/working-with-rgba-colour seems to suggest that it's possible, but I can't seem to get it to work. When I try the following: <!DOCTYPE html PUBLIC "-//W3C//DTD
