css-transforms

I'm using this script that claims to implement matrix3d operation as described in the spec , however the script is missing matrix perspective operations, so I "cooked" something I'm not sure is either accurate or correct. // the perspective matrix to multiply with CSSMatrix.Perspective = function(x, y, z){ var m = new CSSMatrix(); m.m13 = x; m.m23 = y; m.m33 = z; return m; }; and the method to use this matrix // myMatrix.perspective(x,y,z); to apply a perspective matrix CSSMatrix.prototype.perspective = function(x, y, z){ if (y == null) y = 0; if (z == null) z = 0; return CSSMatrix.multiply

When I use scale or rotate , the parent element wraps to the size of the pre-translation dimensions of the element. JSFiddle Example Is there any way to wrap the parent container around the bounding box of the transformed element with CSS, or do I need to use Maths to manually position things? Matthew Green Based on this earlier question it sounds like you will need to use some math and javascript to change the wrapper. By using the function in the answer you could then set the wrapper dimensions based on the dimensions you just calculated. 来源： https://stackoverflow.com/questions/14246982/how

How can I flip multiple div 's when I clicked on menus using CSS3? This code is working for only the last two div s : HTML Code <ul class="nav"> <li><a href="#home">home</a></li> <li><a href="#about">about</a></li> <li><a href="#work">work</a></li> <li><a href="#contact">contact</a></li> </ul> <section class="container"> <div id="card"> <div class="front flipper" id="home">home</div> <div class="back flipper" id="about">about</div> <div class="front flipper" id="work">work</div> <div class="back flipper" id="contact">contact</div> </div> </section> CSS Code .container { width: 500px; height:

So the basic idea is 1 - 9 seats at a curved table as though you are looking at them through first person view. I'm trying to get div elements which would be seats to flow on the outside of another div element that has a border radius to make it a semi oblong circle. I've found a few examples with an element being animated to flow across the container in an arc, but I will need the div/seats to be static. I am looking for any ideas or examples that can lead me in the right path. Finding points on ellipse and translating: If your oblong circle resembles an ellipse then you can find points on

I think it is true that when we do a CSS3 transform translate using a percentage value, then that percentage is relative to its own width or height, so (50%, 75%) means 50% of its own width, 75% of its own height, but I can't find any specs that say that. Example: https://jsfiddle.net/cstsyw3s/1/ using: transform: translate(100%, 100%) I looked into http://www.w3.org/TR/css3-transforms but can't find it mentioned there -- I could only find such as for transform-origin , the "percentages: refer to the size of bounding box", and I think the bounding box probably is rectangle with the element's

I've got a cube element being rotated and translated in a 3d space. I want to find out just the rotateY portion of this transform at a given time. Is this possible? I have: var cube = document.getElementById("cube"); var transform = getComputedStyle(cube).webkitTransform; //the value of transform is: // matrix3d(-1, 0, 0.00000000000000012246467991473532, 0, // 0, 1, 0, 0, // -0.00000000000000012246467991473532, 0, -1, 0, // 0, 0, 0, 1) Help? :-) If your object is only being rotated about Y, then yes, the rotation is simple to calculate - it's the arccos of Matrix elements 1,1 or 3,3 or the

i'm a bit lost here, i'm currently testing the IE10 (10.0.9200.16384) that came with the Windows 8 Release Preview, and i'm having a very hard time. One of the things that are bugging me, is that IE doesn't seem to handle nested 3D Transforms corrently. Please see this fiddle: http://jsfiddle.net/uUHdF/1/ There are two colored divs, a red one, and a green one rotated and translated so that it acts as the top of a cuboid, and this cuboid itself is rotated and translated too (note that i can't use transform-origin with rotate only because it is/was buggy in Webkit... just in case that might be

I have an element that needs to animate left and right to the amount of 50% of its full width. I've accomplished this with the following (simplified) markup: <div class="wrapper"> <div class="inner">Inner</div> </div> And style: .wrapper { position: relative; width: 300px; height: 200px; } .inner { position: absolute; top: 0; right: 0; bottom: 0; left: 0; animation: MOVE_AROUND 5s infinite; } With keyframe animation: @keyframes MOVE_AROUND { 0%, 10% { transform: translate3d(0, 0, 0); } 20%, 40% { transform: translate3d(-50%, 0, 0); } 60%, 80% { transform: translate3d(50%, 0, 0); } 90%, 100% {
