javascript - AngularJs 过渡水平菜单与 ng-show

Question

我尝试在 AngularJs 中制作水平菜单。我想通过单击按钮淡出菜单。我想通过 css3 过渡实现淡出，但它不起作用。

这是实际代码:

<div class="header-title" ng-bind="pageTitle">
</div>
<div class="content-container" ng-controller="AboutCtrl">
    <div class="navigation-container"  ng-show="checked">
        <li ui-route="/services" ng-class="{active:$uiRoute}" class="navigation-item"><a
                href="#/services">Services</a>
        </li>
        <li ui-route="/services" ng-class="{active:$uiRoute}" class="navigation-item"><a
                href="#/services">Services 1</a>
        </li>
        <li ui-route="/services" ng-class="{active:$uiRoute}" class="navigation-item"><a
                href="#/services">Services 2</a>
        </li>
    </div>
<div class="navbar navbar-inverse">
    <div class="navbar-inner">
        <button ng-init="checked=false" ng-click="checked=!checked" type="button" class="btn btn-navbar">
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
        </button>
    </div>
</div>

<div>content</div>

</div>

实际上我的 CSS 是这样的:

.navigation-container{
max-height:600px;
-webkit-transition: all 0.3s ease-out;
-moz-transition: all 0.3s ease-out;
-ms-transition: all 0.3s ease-out;
-o-transition: all 0.3s ease-out;
transition: all 0.3s ease-out;
}

.header-title{
background-color: #dddddd;
padding: 15px 20px;
text-align: center;
color: #333333;
font-weight: bold;
font-size: 20px;
}

.navigation-item{
list-style:none;
background-color: white;
text-align: center;
color: #777777;
font-size: 12px;
font-weight: normal;
line-height: 1.4;
border-bottom:dotted 1px #dddddd;
}

.navigation-item > a {
padding: 15px;
display: block;
-webkit-transition: all 0.3s ease-out;
    -moz-transition: all 0.3s ease-out;
    -ms-transition: all 0.3s ease-out;
    -o-transition: all 0.3s ease-out;
    transition: all 0.3s ease-out;
}

.navigation-item > a:hover{
background-color: #eeeeee;
text-decoration:none;
}

我想通过单击按钮淡出类“navigation-container”。任何人都可以帮我为此做 css 吗？
