Interruption of a CSS transition does not work for same attribute value

阅读更多关于 Interruption of a CSS transition does not work for same attribute value

I've answered a question on how to start an animation when hovering the child element and then preserve the applied style until un-hovering the parent. However, I discovered a behaviour in my proposed solution that I can't explain and that I would like to understand. Reading the relevant parts of the specification didn't help me. Here is a minimal example showing the expected behaviour. It works but the properties with comments behind have to be different for some reasons. Otherwise (e.g. both having 10px as value) un-hovering of the parent won't do anything to the width of the child. JSFiddle

Browser-specific prefixes with a CSS transition on transform

阅读更多关于 Browser-specific prefixes with a CSS transition on transform

问题 According to caniuse.com, for those browsers that support both CSS transition and CSS transform , combinatorically there are at least three different types: Those that require the -webkit- prefix on both transition and transform (e.g. Safari 6, Android browser < 4.4). Those that only require the -webkit- prefix on transform (e.g. Chrome 3x). Those that require prefixes on neither (e.g. FF and IE10/11). How can I safely write my transition styles so that they are parsed correctly in each type?

Why does IE10 require the presence of a p:hover {} rule for transitions to work on a pseudo element?

阅读更多关于 Why does IE10 require the presence of a p:hover {} rule for transitions to work on a pseudo element?

HTML: <p>Hover</p> CSS: p::after { content: " here"; transition: all 1s; } p:hover::after { font-size: 200%; color: red; } Live demo: http://jsfiddle.net/SPHzj/13/ (works in Firefox and Chrome) As you can see, I've set up CSS transitions on the ::after pseudo-element of the paragraph. Then, when the paragraph is hovered, two new styles apply for the pseudo-element which are transitioned. This works in Firefox and Chrome, but not in IE10. My reasoning was that IE doesn't understand the p:hover::after selector, as it works in IE if you set the hover on an ancestor element, e.g. div:hover p:

CSS Filter on Retina Display: Fuzzy Images

阅读更多关于 CSS Filter on Retina Display: Fuzzy Images

问题 When you apply a -webkit-filter and a -webkit-transition to an Image and change the filter on hover, the image transition does well, but then the image gets really fuzzy. Note: This only happens on Retina-Displays — no problem at all with 'normal' ppi-displays, but fuzzy on for example a new MacBook Pro with Retina Display. My CSS (without vendor-prefixes): img {filter:grayscale(1);filter:saturate(0%);transition:2s ease;width:200px;height:200px} img:hover {filter:grayscale(0)} Note: to see

collapse transition not working with angular's UI Bootstrap

阅读更多关于 collapse transition not working with angular's UI Bootstrap

I'm trying to create a div which will show / hide when a button is clicked. The UI Bootstrap page shows a nice simple example that uses a css transition. Here's my fiddle where I copy their code, almost exactly (slight change to make html syntax highlighting work, and a line to declare my "app" in the js). As you can see, it doesn't work as in the example -- there is no transition. Why not? Maybe a css transition rule is needed -- but isn't that part of what bootstrap.css provides? for posterity, the equivalent html file from the fiddle would be: <html> <head> <link rel="stylesheet" type="text

Using CSS3 transforms/animations with font-face produces “wobbly” spinner gif-like

阅读更多关于 Using CSS3 transforms/animations with font-face produces “wobbly” spinner gif-like

I'm using CSS transforms/animations with font-face ( twitter bootstrap/font-awesome ) to produce a spinner gif-like icon. The problem is that the icon wobbles as it revolves around 360degrees. See this JSFiddle to see what I mean. Does anyone know how to make it not wobble? Or at least make it rotate a little more smoothly? Here's the code for that below: CSS: i.icon-repeat { -webkit-animation: Rotate 500ms infinite linear; -moz-animation: Rotate 500ms infinite linear; -ms-animation: Rotate 500ms infinite linear; -o-animation: Rotate 500ms infinite linear; animation: Rotate 500ms infinite

I am missing something obvious. But the transition on only one element isn't working here.
