Hover div to trigger an animation effect in another icon

I need to adjust the CSS animation effects in the icon when I find mine div.

CSS

.animated-div {
    -webkit-animation-name: flipInX;
    animation-name: flipInX;
    -webkit-animation-duration:1s;
    animation-duration: 1s;
    -webkit-animation-fill-mode: both;
    animation-fill-mode: both;
}
.newsline:hover .animated-div, .newsline:focus .animated-div, .newsline:active .animated-div {
    -webkit-animation-name: flipInX;
    animation-name: flipInX;
    -webkit-animation-duration:1s;
    animation-duration: 1s;
    -webkit-animation-fill-mode: both;
    animation-fill-mode: both;
}

HTML

<div class="box-head">
    <i class="fa fa-reorder fa-2x pull-left fa-border animated-div"></i>
</div>
</br></br></br>
<div class="newsline">test</div>

In action, this does not work!

How can i fix it?

There is no previous selector in CSS, so the effect you need cannot be achieved using pure CSS without changing the markup.

CSS approach:

If you can change your markup to something like below (basically move divover the icon container):

<div class="newsline">test</div>
<div class="box-head">
    <i class="fa fa-reorder fa-2x pull-left fa-border animated-div"></i>
</div>

then you can use the below CSS to start the animation when it crashes div.

.newsline:hover + .box-head > .animated-div {
    -webkit-animation-name: flipInX;
    animation-name: flipInX;
    -webkit-animation-duration:1s;
    animation-duration: 1s;
    -webkit-animation-fill-mode: both;
    animation-fill-mode: both;
}
