Question

这是一个非常直截了当的问题，但我找不到关于CSS过渡属性的非常好的文档。这是CSS片段：

    .nav a
{
    text-transform:uppercase;
    text-decoration:none;
    color:#d3d3d3;
    line-height:1.5 em;
    font-size:.8em;
    display:block;
    text-align:center;
    text-shadow: 0 -1.5em 0 rgba(255, 255, 255, 0.15);
    -webkit-transition: color .2s linear;
    -moz-transition: color .2s linear;
    -o-transition: color .2s linear;
    transition: color .2s linear;
    -webkit-transition: text-shadow .2s linear;
    -moz-transition: text-shadow .2s linear;
    -o-transition: text-shadow .2s linear;
    transition: text-shadow .2s linear;
}

.nav a:hover
{
    color:#F7931E;
    text-shadow: 0 1.5em 0 rgba(247, 147, 30, 0.15);
}

如您所见，过渡属性会相互覆盖。就目前而言，文本阴影将动画，但不是颜色。我怎样让他们同时动画？谢谢你的回答。

Answer 1

转换属性在所有支持转换的浏览器中以逗号分隔：

.nav a {
  transition: color .2s, text-shadow .2s;
}

ease是默认的计时功能，因此您无需指定它。如果您真的想要linear，则需要指定它：

transition: color .2s linear, text-shadow .2s linear;

这开始变得重复，所以如果您要在多个属性中使用相同的时间和计时功能，最好继续使用各种transition-*属性而不是速记：

transition-property: color, text-shadow;
transition-duration: .2s;
transition-timing-function: linear;

Answer 2

您还可以简单地使用：

.nav a {
    -webkit-transition: all .2s;
}

Answer 3

以下内容将允许同时进行多次转换：

-webkit-transition: color .2s linear, text-shadow .2s linear;
   -moz-transition: color .2s linear, text-shadow .2s linear;
     -o-transition: color .2s linear, text-shadow .2s linear;
        transition: color .2s linear, text-shadow .2s linear;

Answer 4

如果您将所有属性设置为相同的动画，则可以单独设置每个属性，这样您就不会重复代码。

 transition: all 2s;
 transition-property: color, text-shadow;

我会避免全部使用属性（transition-property覆盖＆＃39; all＆＃39;），因为最终可能会出现意外行为和意外性能下降。

Answer 5

.nav a {
    transition: color .2s, text-shadow .2s;
}

Answer 6

这是一个LESS mixin，用于同时转换两个属性：

.transition-two(@transition1, @transition1-duration, @transition2, @transition2-duration) {
 -webkit-transition: @transition1 @transition1-duration, @transition2 @transition2-duration;
    -moz-transition: @transition1 @transition1-duration, @transition2 @transition2-duration;
      -o-transition: @transition1 @transition1-duration, @transition2 @transition2-duration;
          transition: @transition1 @transition1-duration, @transition2 @transition2-duration;
}

Answer 7

可以使多个转换设置为持续时间，延迟和定时功能的不同值。要分割不同的转换，请使用,

button{
  transition: background 1s ease-in-out 2s, width 2s linear;
  -webkit-transition: background 1s ease-in-out 2s, width 2s linear; /* Safari */
}

Answer 8

还可以避免完全指定属性。

#box {
  transition: 0.4s;
  position: absolute;
  border: 1px solid darkred;
  bottom: 20px; left: 20px;
  width: 200px; height: 200px;
  opacity: 0;
}

#box.on {
  opacity: 1;
  height: 300px;
  width: 500px;
 }

在 Sass 中，您可以使用以下代码实现

@mixin transition($transitions...) {
  $unfoldedTransitions: ();
  @each $transition in $transitions {
    $unfoldedTransitions: append($unfoldedTransitions, unfoldTransition($transition), comma);
  }
  
  -webkit-transition: $unfoldedTransitions;
  transition: $unfoldedTransitions;
}

@function unfoldTransition ($transition) {
  // Default values
  $property: all;
  $duration: .2s;
  $easing: null; // Browser default is ease, which is what we want
  $delay: null; // Browser default is 0, which is what we want
  $defaultProperties: ($property, $duration, $easing, $delay);

  // Grab transition properties if they exist
  $unfoldedTransition: ();
  @for $i from 1 through length($defaultProperties) {
    $p: null;
    @if $i <= length($transition) {
      $p: nth($transition, $i)
    } @else {
      $p: nth($defaultProperties, $i)
    }
    $unfoldedTransition: append($unfoldedTransition, $p);
  }

  @return $unfoldedTransition;
}

// Usage:   @include transition(width, height 0.3s ease-in-out);
