在Sass中，你可以使用下面的代码来实现

@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);

下面的代码允许同时进行多个转换:

-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;

例如:http://jsbin.com/omogaf/2

在所有支持转换的浏览器中，转换属性以逗号分隔:

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

Ease是默认的计时函数，所以您不必指定它。如果你真的想要线性，你需要指定它:

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

这开始变得重复，所以如果你打算在多个属性中使用相同的时间和计时函数，最好继续使用各种过渡-*属性，而不是简写:

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

在Sass中，你可以使用下面的代码来实现

@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);

编辑:我在犹豫是否要删除这篇文章。就理解CSS语法而言，让人们知道所有的声明都存在是件好事，有时这可能比上百万个单独的声明更好，这取决于您的CSS结构。另一方面，它可能会有性能损失，尽管我还没有看到任何数据支持这一假设。现在，我就不谈这个问题了，但我希望人们知道这是一个混合的袋子。

原来的帖子:

你也可以简单地显着:

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

FWIW:如果没有指定，则暗示all，因此transition: .2s;会把你送到相同的地方。

也可以完全避免指定属性。

#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;
 }
