I am trying to make a slide down using CSS transitions. The starts off at height: 0;. On hover, the height is set to height:auto;. However, this is causing it to simply appear, not transition, If I do it from height: 40px; to height: auto;, then it will slide up to...
打开时再设置{visibility:visible} .faq_sub_content li .container{ width:100%; transition:all 0.3s cubic-bezier(0.4, 0, 1, 1); -webkit-transition:all 0.3s cubic-bezier(0.4, 0, 1, 1); -webkit-opacity:0; opacity:0; height:0; overflow: hidden;} .faq_sub_content li .detai...
通过js计算 auto的高度,然后设置height具体值。 css代码: .block{width:200px;height:100px;border:1px solid red;padding:20px;overflow:hidden;transition:all ease 0.8s; } js代码: $('button').click(function() {varBlock = $('.block');varheight =Block.height(); console.info(height);if(heigh...
需求是有一些动态内容折叠起来的，点击后弹开 js定时器的动画过渡暂不考虑，于是就想到transition过渡 一开始就想着用trasition动画过渡就搞定啦，试了一下后，发现有问题 折叠的元素的高度height必须得设置一个值才可以有过渡的效果，要不就过渡不了 折中一下，就用js动态获取子元素的高度，然后给值到...
从MDN的可以查到 CSS 支持动画的属性中的 height 属性如下: 当height 的值是 length,百分比或 calc() 时支持 CSS3 过渡。 所以当元素 height : auto 时,是不支持 CSS3 动画的。 除了通过 JS 获取精确的 height 值的方法外,其实我们可以使用 max-height 代替 height。
This is the relevant CSS: .invite-panel{height:0;overflow-y:clip;transition:height0.25sease-in;} On click, JavaScript sets auto height on the element as an inline style to override the CSS: Thetransitionproperty in CSS lets the browser know that...
(Edited: current resolved-on proposal is at #626 (comment)) https://drafts.csswg.org/css-transitions/#animtype-rect It would be incredibly useful to be able to transition to (or from) height: auto. As it stands now, you need to jump thro...
其实解决方式也很简单,对于动态内容,元素的高度应设置为 auto。这样,任何增加或减少的元素高度都将自适应。但也会出现另一个问题:当元素的高度设置为 auto 时,CSS transition 将不起作用。 好消息是,有一种方法可以解决此问题,而不必求助于更多的 JavaScript。
这个在Using CSS transitions文档中有专门的解释: The auto value is often a very complex case. The specification recommends not animating from and to auto. Some user agents, like those based on Gecko, implement this requirement and others, like those based on WebKit, are less strict. Using anima...
