Any help? 回答1: I had a view that contained a list of camps, and touching one takes users to the camp details.

原则 : 对谁做过渡,过渡效果就加在谁身上. 一、2D变形—移动 translate : 在2D范围内移动可以单独设置X、Y轴,也可以结合使用 transition : 结合translate使用,过渡效果的属性、时间以及何种效果 < !

CSS Transition for only one type of transform?

阅读更多关于 CSS Transition for only one type of transform?

问题 Is it possible to animate (using transitions) only one type of css transform? I have css: cell{ transform: scale(2) translate(100px, 200px); transition: All 0.25s; } Now, I want only scale to be animated. In this case I could use position:absolute and left/right properties but I far as I remember, translate() is much better in performance. I would also like to avoid using additional html elements. Fiddle: http://jsfiddle.net/6UE28/2/ 回答1: Yes! You separate it into two selectors, one of them

过渡 - transition

阅读更多关于过渡 - transition

过渡 - transition 是变形 transfrom 其中一种效果，定义为一种状态过渡到另一种状态的过程，今天学习到css3动画，特此记录下过渡的使用和一些效果。实例1： <div class="box"></div> <p>鼠标移动到 .box 元素上，查看过渡效果。</p> .box{ width: 100px; height: 100px; background: red; margin: 0 auto; transition-duration: 1s; /*花费时间*/ transition-property: all; transition-delay:0s; /* 延迟 */ transition-timing-function: linear; /*匀速*/ } .box:hover{ width:200px; background: #00FFFF; } 效果图：注：当指针移出元素时，它会逐渐变回原来的样式。实例2：在例子中使用所有过渡属性 - 使用简写 .box{ .box{ width: 100px; height: 100px; background: red; margin: 0 auto; transition:1s all 0s linear; } 效果图还是这样： -------------------------------------

纯CSS Material Design风格按钮

阅读更多关于纯CSS Material Design风格按钮

其实Material Design的扁平化icon按钮，这类型的按钮往往只利用几何色块的变化，就能抓住使用者的眼光，并且从几何形状中明白按钮的含意，这也是Material Design非常强调的设计理念和精髓。应用重点与原理在这篇我纯粹利用CSS，就做出了Material Design风格的按钮，其实没有很难，比较需要知道的重点如下：伪元素before和after的应用伪元素在里头扮演相当重要的角色，利用伪元素我们可以产生两个不在HTML里头的类div，可以大幅降低代码的复杂程度。 div的自身宽度与边框由于我们要进行三角形与矩形之间的形变，虽然三角形可由边框产生，但却无法做出漂亮的形变效果（用背景色的话就会有淡入淡出的现象），所以必须要用边框宽度和矩形大小去搭配，当边框变细的时候，矩形变大，如此一来就可以做出三角形与矩形互相变换的效果啰，下图的红色是纯粹用颜色变换，蓝色则是用边框宽度与div宽度变换，效果应该很明显吧！ transform的应用 CSS里所有的形变都是藉由transform来完成（必要时请加各个浏览器的前坠字），示例里头会用到scale与rotate这两个变形属性。实现Material Design风格按钮了解原理之后，先来看一下HTML代码，代码里面有两个主要的div分别是a和b，a的话是利用伪元素来进行变换，b的内容还有三个小i分别是b1

问题 I am trying to create a real time graph using nvd3.js which would be updated periodically and with the impression that the data is processed in real time. For now I have been able to create a function which would update the graph periodically but I cannot manage to have a smooth transition between "states" like the line doing a transition to the left. Here is what I did using nvd3.js , here the interesting code is: d3.select('#chart svg') .datum(data) .transition().duration(duration) .call

问题 I'm trying to achieve a view transition like the new iOS7 weather app transition, using a collapsing/expanding view. Does anyone know if a lib already exist for that ? Thanks 回答1: User antol put some effort into replicating the behavior: https://github.com/Antol/APPaginalTableView But note that APPaginalTableView doesn't have a separate controller for the expanded pages. You can see it in action here: https://www.youtube.com/watch?v=X1YvxDMr0yA 回答2: EDIT Check out this project. It
