如何动画定位固定？

Question

我尝试动画一个在1秒后修复的DIV.但我无法完成它.我希望在一秒之后,div称为"homepage-hero-module"从右向左滑动.正如您在FIDDLE中看到的那样,它会在一秒后变为固定.那么如何动画呢？

我试过用css,但没有运气.

-webkit-transition: left 1s;
  -moz-transition: left 1s;
  -o-transition: left 1s;
  transition: left 1s;

和

-webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;

的jsfiddle

HTML代码:

<div class="container-fluid">
    <div class="homepage-hero-module">
        Container with data
    </div>
</div>

CSS代码:

    body, html {
  margin: 0px;
  padding: 0px;
  width: 100%;
  height: 100%;
}
.container-fluid {
  width: 100%;
  height: 100%;
  position: relative;
}
.homepage-hero-module {
  background: #DDD;
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0px;
  left: 0px;
}
.fixed {
    position: fixed;
    top: 0px;
    left: 0px;
    width: 20px;
    height: 100%;
    background: red;
}
img {
  height: 100%;
  width: auto;
}

JS代码:

$(document).ready(function() {
    setTimeout( function(){
              $('.homepage-hero-module').addClass('fixed');
    },1000);
});

您需要在位置仍然是绝对的情况下为宽度设置动画，然后将位置设置为固定

<div class="container-fluid">
    <div class="homepage-hero-module">
        Container with data
    </div>
</div>

body, html {
  margin: 0px;
  padding: 0px;
  width: 100%;
  height: 100%;
}
.container-fluid {
  width: 100%;
  height: 100%;
  position: relative;
}
.homepage-hero-module {
  background: #DDD;
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0px;
  left: 0px;
  transition:all .2s ease;
}
.fixed {
    top: 0px;
    left: 0px;
    width: 20px;
    height: 100%;
    background: red;
}
img {
  height: 100%;
  width: auto;
}

$(document).ready(function() {
setTimeout( function(){
    $('.homepage-hero-module').addClass('fixed');
},1000);
    $('.homepage-hero-module').css('position','fixed');
});
