本文介绍了如何延迟一个过渡但不延迟另一个过渡？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！问题描述

我为 #circle 设置了两个过渡。

我只希望不透明

我的全部目标是在圆处于中间旋转时使不透明度发生变化（因此正好在90度）。

My full goal is to make the opacity change when the circle is mid spin (so at exactly 90deg).

但是我自己会计算出时间，我只想知道如何将延迟仅用于一次过渡

But I will work out the timing myself, I just want to know how to give the delay to only one transition.

#circle { background-color:black; background-image:url('rain.img'); height:300px; width:300px; border-radius:100%; margin:0 auto; perspective:1000; transition:transform 2s, opacity .1s; } #circle:hover { perspective:1000px; transform:rotateY(180deg); opacity:.25; }

我想您只需要查看CSS，但是如果您认为需要查看完整代码 ===> jsfiddle/z49kd9qk /

I imagine you will only need to see the CSS, but if you think you need to see the full code go here ===> jsfiddle/z49kd9qk/

任何帮助将不胜感激！

推荐答案

解决方案

转换延迟函数只能解析为第二个计时值。

Solution

The transition-delay function can only be parsed as the second timing value.

取而代之的是：

transition: transform 2s, opacity .1s;

与此工作：

transition: transform 2s 0s, opacity 0s 2s;

说明

使用 transition 速记属性时，组件的顺序和存在很重要。基本顺序和组成如下：

Explanation

When working with the transition shorthand property, the order and presence of components matter. Here's the basic order and composition:

<transition-property> <transition-duration> <transition-timing-function> <transition-delay>

如果剩余转换属性组件则，简写属性适用于 all 。

If the transition-property component is left out, the shorthand property applies all.

如果 transition-timing-function-函数组件被省略，速记适用 ease 。

If the transition-timing-function component is left out, the shorthand applies ease.

（均为初始值

因此您可以将声明最小化：

So you can minimize the declaration to this:

<transition-duration> <transition-delay>

如果仅声明一个值（如您的代码中一样），它将始终应用于过渡时间。

If only one value is declared (like in your code), it will always be applied to transition-duration.

因此：

transition: transform 2s, opacity .1s;

...您要将计时持续时间应用于这两个属性。

... you're applying a timing duration to both properties.

转换延迟函数只能解析为第二个计时值。

The transition-delay function can only be parsed as the second timing value.

根据您的问题：

我只希望不透明性有延迟，但我只能将其设为

I want only the opacity to have a delay but I can only make it where both of the transitions do.

然后执行以下操作：

transition: transform 2s 0s, opacity 0s 2s;
