如何为固定位置设置动画？ [英] How to animate to position fixed?

问题描述

我尝试为DIV制作动画，该动画在1秒后会固定。但是我做不到。我希望一秒钟后，名为 homepage-hero-module的div从右向左滑动。正如您在FIDDLE中看到的那样，它在一秒钟后变为固定状态。那么如何制作动画呢？

I try to animate a DIV that gets fixed after 1 second. But I can't make it done. I want after one second the div called "homepage-hero-module" to slide from right to left. As you can see in the FIDDLE it changes to fixed after one second. So How to animate this?

我尝试使用CSS，但是没有运气。

I tried with css, but no luck.

-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;

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);
});    

推荐答案

在位置仍然是绝对值时，需要设置宽度的动画，然后将位置设置为固定

You need to animate the width while position is still absolute, and then set the position to fixed

<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');
});
