为什么css过渡不起作用

Question

我正在尝试添加转换,但它不起作用我添加转换到我的链接并期望悬停状态的变化我使用转换很多,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

我更愿意知道为什么它不起作用

这是我的代码

<div class="subNavigation">
                        <ul>
                            <li>?????? ???? ???</li>
                            <li><a href="javascript:void(0)">?????? ???? ??? 1</a></li>
                            <li><a href="javascript:void(0)">?????? ???? ??? 2</a></li>
                            <li><a href="javascript:void(0)">?????? ???? ??? 3</a></li>
                            <li><a href="javascript:void(0)">?????? ???? ??? 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;

 .subNavigation a {

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

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;

改成:

-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.如果要声明多个转换,那么您可以用逗号分隔它们.

请参阅W3C Docs或/和CSS3.info

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

在哪里<single-transition>:

<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 */
