CSS3 transition on click using pure CSS

由 痞子三分冷 提交于 2019-12-17 04:28:41
问题 I'm trying to get an image (a plus symbol) to rotate 45 degrees to create a cross symbol. I have so far managed to achieve this using the code below but its working on hover, I wanted to have it rotate on click. Is there a simple way of doing so using CSS ? My code is: CSS img { display: block; margin: 20px; } .crossRotate { -webkit-transition-duration: 1s; -moz-transition-duration: 1s; -o-transition-duration: 1s; transition-duration: 1s; -webkit-transition-property: -webkit-transform; -moz

CSS: pure CSS scroll animation

由 左心房为你撑大大i 提交于 2019-12-17 04:13:01
问题 I have been looking for a way to scroll down when clicking on a button that is located on top of a page using CSS3 only. So I've found this tutorial: http://tympanus.net/codrops/2012/06/12/css-only-responsive-layout-with-smooth-transitions/ Demo: http://tympanus.net/Tutorials/SmoothTransitionsResponsiveLayout/ But it's a bit too advanced for my needs since I just want the browser to scroll down on a click on one button located on top of the page, so I was wondering: is it possible to do those

CSS变化、过渡与动画

由 人走茶凉 提交于 2019-12-17 03:29:30
CSS 变换 用于在空间中移动物体，而CSS 过渡 和CSS 关键帧动画 用于控制元素随时间推移的变化。 变换、过渡和关键帧动画的规范仍然在制定中。尽管如此，其中大多数特性已经在常用浏览器中实现了。 1.二维变换 CSS变换支持在页面中平移、旋转、变形和缩放元素。 从技术角度说，变换改变的是元素所在的坐标系统。 任何落在元素渲染空间内的像素都会被 畸变场 捕获，然后再把它们传输到页面上的新位置，或改变大小。元素本身还在页面上原来的位置，但它们畸变之后的“影像”已经变换了。 <div class="box"></div> .box { /* 省略 */ width: 100px; height: 100px; background-color: #eee; outline: 1px solid; transform: rotate(45deg); /* 旋转45度角 */ } 页面上元素原来的位置仍然保留了100像素×100像素的空间，但元素上所有的点都被畸变场给变换到了新位置。 旋转后的矩形不会妨碍页面其他部分的布局，就好像根本没有变换过一样。 1.1 变换原点 默认情况下，变换是以元素边框盒子的中心作为原点的。控制原点的属性叫 transform-origin 。 .box { transform-origin: 10px 10px; transform: rotate

CRF/Seq2Seq/CTC的Loss实现对比

由 本秂侑毒 提交于 2019-12-16 08:05:34
CRF/Seq2Seq/CTC的目标函数对比（CRF Loss解析） 这里基于TensorFlow的实现，对三种序列化的任务的目标函数做一个总结。 1. 序列化任务的定义和训练 输入输出都是序列。 先明确下三个任务的不同： CRF：通常用于序列标注任务，比如：BiLSTM+CRF、IDCNN+CRF，场景的特点是， 输入与输出是一一对应的 。 其中语义模型先根据输入生成每个字的“打分”（后验概率的-log），作为解码时的反向观测概率。 Seq2Seq：通常用于生成式问答、摘要生成、机器翻译等等，一般是一种编码器和解码器的结构，特点是：输入与输出长度不一定相同。 CTC解码：一种语音识别的方法，输入为语音，输出为文字，特点是：一种输出可能对应着多个正确的路径。 CTC可以参考：https://distill.pub/2017/ctc/ 三个问题都是解码问题，因为特点的不同，目标函数也不一样： 对于CRF来说目标函数包含两个部分： loss = unary potential + pairwise potential = ClassifyLoss + TranstionLoss （名字是我自己编的，感觉好理解一些），然后用句子的真实长度做mask。 ClassifyLoss（unary potential）：语义模型会生成每个字的得分，其实就是预测的tag在tags词典中的概率的

a compact way to code chained transitions in D3

由 妖精的绣舞 提交于 2019-12-14 04:19:17
问题 I have to apply two long sequences of chained transitions which differ mainly in the order of transitions on some elements, and I'm looking for a compact way to code. Suppose (only as a toy example) that I have two circles and I have to apply the following colors to the first one: orange -> purple -> blue -> yellow ; and the following colors to the second one: blue -> yellow -> orange -> purple . I've tried with the code below (fiddle here), but it doesn't work. Which is the most compact way

CSS transition only one transform function

由 爷，独闯天下 提交于 2019-12-14 00:33:52
问题 Is there a way to animate only one transform function? For example i only want my transition on scale function. How will i do this .my-class { transition: transform; } .large { transform: scale(2) rotate(90deg); } <div class="my-class"></div> <div class="my-class large"></div> 回答1: I played around with your code a little and YES you can. Just assign the different transform functions to different classes and use only those classes that you want...like so. Importantly DO NOT FORGET to use the

CSS 3 - Scale transition snaps back in google chrome

由 与世无争的帅哥 提交于 2019-12-13 14:28:56
问题 I have an issue , I have the following code I am using for increasing the scale using CSS3 transition , at the end it snaps back to its original scale after increasing. CSS: .big{ transition:all 0.3s ease-in-out; display:inline; } .big:hover{ -webkit-transform:scale(1.4); } HTML : <h1 class = "big">Typo</h1> 回答1: Try using inline-block instead of inline (also, it's recommended to add compatibility to the rest of the browsers as well). CSS: .big { -webkit-transition: all 0.3s ease-in-out; -moz

Receiving elements position in the middle of CSS transition

由 好久不见. 提交于 2019-12-13 14:17:31
问题 I need to receive the elements left and top property in the middle of the CSS transition. Currently I use jQuery position method and it seem to be working to some point. I have made 2 examples to show my problem more clearly: 1) Here is NON -working example where position of element is printed to console. The correct position is received till the elements transition is changed to its original position. After the first change in transform value, the position is not updated anymore. jsFiddle

Flipping UIViews From Top / Bottom

由 佐手、 提交于 2019-12-13 12:05:41
问题 I'm well aware that there are only two available UIView transitions, UIViewAnimationTransitionFlipFromLeft and UIViewAnimationTransitionFlipFromRight. I'm wondering if there is anyway that I can implement / emulate a UIViewAnimationTransitionFlipFromTop or UIViewAnimationTransitionFlipFromBottom. The only way I can think to do this is by flipping the x axis with the y axis, but I've not seen any information about how to do this. Just setting the coordinates of each axis won't fix the issue as

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 3 years ago . I'm using R and need some help. Background: I video-recorded participants in a behavioural study. I then coded different aspects of their behaviour from the videos so that I now have one data frame per participant. The df has many unordered factors, each representing the discrete
