Question

我正在尝试添加转换，但它不起作用我添加了转换到我的链接并期望更改悬停状态我使用过渡很多，但有时这发生在我身上，我不知道为什么这个属性不起作用

我更喜欢知道为什么它不起作用

这是我的代码

<div class="subNavigation">
                        <ul>
                            <li>درباره بانک مهر</li>
                            <li><a href="javascript:void(0)">درباره بانک مهر 1</a></li>
                            <li><a href="javascript:void(0)">درباره بانک مهر 2</a></li>
                            <li><a href="javascript:void(0)">درباره بانک مهر 3</a></li>
                            <li><a href="javascript:void(0)">درباره بانک مهر 4</a></li>
                        </ul>
                    </div>

和css

.subNavigation {
 width: 900px;
 height: 274px;
 position: absolute;
 top: 40px;
 right: 0;
 padding: 30px 60px 0 0;
 }
 /* line 126, ../sass/style.scss */
 .subNavigation ul {
 float: right;
 }
 /* line 130, ../sass/style.scss */
 .subNavigation li {
 width: 153px;
 *zoom: 1;
 margin-top: 4px;
 padding-right: 2px;
 padding-bottom: 4px;
 border-bottom: 1px dotted #b4b4b4;
 }
 /* line 38, D:/Ruby193/lib/ruby/gems/1.9.1/gems/compass-      0.12.2/frameworks/compass/stylesheets/compass/utilities/general/_clearfix.scss */
.subNavigation li:after {
 content: "";
 display: table;
 clear: both;
 }
/* line 138, ../sass/style.scss */
.subNavigation li:first-child {
width: 155px;
height: 24px;
margin-top: 0;
margin-bottom: 14px;
color: #f7931e;
border-bottom: 1px solid #dddddd;
padding-right: 0;
font-size: 16px;
line-height: 24px;
}
/* line 151, ../sass/style.scss */
 .subNavigation a {
  float: right;
  font-size: 13px;
   height: 24px;
   line-height: 24px;
   padding-right: 2px;
  color: #222;
  -webkit-transition: all, 0.2s, ease-in;
  -moz-transition: all, 0.2s, ease-in;
  -o-transition: all, 0.2s, ease-in;
   transition: all, 0.2s, ease-in;
   }
  /* line 160, ../sass/style.scss */
 .subNavigation a.eng {
  font-family: tahoma;
  }
 /* line 164, ../sass/style.scss */
 .subNavigation a:hover {
  padding-right: 10px;
  border-right: 4px solid #f7941d;
  color: #19ae61;
  }

The Fiddle

Answer 1

一个简单的错误：

-webkit-transition: all, 0.2s, ease-in;
-moz-transition: all, 0.2s, ease-in;
-o-transition: all, 0.2s, ease-in;
transition: all, 0.2s, ease-in;

更改为：

-webkit-transition: all 0.2s ease-in;
-moz-transition: all 0.2s ease-in;
-o-transition: all 0.2s ease-in;
transition: all 0.2s ease-in;

演示：http://jsfiddle.net/X5UBF/1/

转换值不以逗号分隔。它们是一个单一的声明。如果你想声明多个转换，那么你可以用逗号分隔它们。

请参阅W3C Docs或/和CSS3.info

Value: <single-transition> [ ‘,’ <single-transition> ]*

<single-transition>的位置：

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

因此，逗号分隔的示例将是：

transition: opacity 0.5s ease-in, width 1.5s ease-out;
/* 0.5s for an opacity transform while 1.5s for a width transform */

Answer 2

过渡宣言不正确：

 -webkit-transition: all 0.2s ease-in;  /* Chrome 1-25, Safari 3.2+ */
 -moz-transition: all 0.2s ease-in;  /* Firefox 4-15 */
 -o-transition: all 0.2s ease-in;  /* Opera 10.50–12.00 */
 transition: all 0.2s ease-in;  /* Chrome 26, Firefox 16+, IE 10+, Opera 12.10+ */

为什么css过渡不起作用
