悬停div在另一个图标中触发动画效果。

I need to set CSS animation effects in icon when I hover my div.

当我悬停div时，我需要在图标中设置CSS动画效果。

.animated-div {
    -webkit-animation-name: flipInX;
    animation-name: flipInX;
    -webkit-animation-duration:1s;
    animation-duration: 1s;

There is no previous sibling selector in CSS and hence the effect you need cannot be achieved using pure CSS alone without changing your markup.

CSS中没有之前的同级选择器，因此，如果不更改标记，仅使用纯CSS就无法实现所需的效果。

CSS Approach:

CSS的方法:

If you can change your markup to something like below (basically move the div above the icon's container):

如果可以将标记更改为如下所示(基本上将div移动到图标容器之上):

<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 trigger the animation while hovering the div.

然后，您可以使用下面的CSS来触发动画，同时在div中悬停。

.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;
}

Selector explanation:

选择器的解释:

.newsline:hover + .box-head > .animated-div

• Select the element with class='animated-div'
• 选择class='animated-div'的元素
• which is a child of another element with class='box-head'
• 它是另一个元素的子元素class='box-head'
• which is in-turn the adjacent sibling of the element with class='animated-div'
• 也就是元素的邻边元素class='animated-div'
• when the element with class = 'animated-div' is being hovered on.
• 当class = 'animated-div'的元素悬置时。

jQuery Approach:

jQuery的方法:

If you cannot modify your structure for whatever reasons, then you need to create a separate onhover class like given below:

如果由于任何原因无法修改结构，则需要创建一个单独的onhover类，如下所示:

.onhover {
    -webkit-animation-name: flipInX;
    animation-name: flipInX;
    -webkit-animation-duration:1s;
    animation-duration: 1s;
    -webkit-animation-fill-mode: both;
    animation-fill-mode: both;
}

and use jQuery (or JavaScript) to add the class to the .animated-div while hovering on .newsline.

并使用jQuery(或JavaScript)在.newsline上悬停时将类添加到.animated-div。

$(document).ready(function(){
    $('.newsline').hover(function(){
        $(this).prev('.box-head').children('.animated-div').addClass('onhover');
    }, function(){
        $(this).prev('.box-head').children('.animated-div').removeClass('onhover');
    });
});

$(document).ready(function(){
    $('.newsline').hover(function(){
        $(this).prev('.box-head').children('.animated-div').addClass('onhover');
    }, function(){
        $(this).prev('.box-head').children('.animated-div').removeClass('onhover');
    });
});

<div class="newsline">test3</div>

Selector explanation:

选择器的解释:

$(this).prev('.box-head').children('.animated-div')

• Select the element with class='animated-div'
• 选择class='animated-div'的元素
• which is a child of an element with class='box-head'
• 它是具有class='box-head'的元素的子元素
• which is in-turn the previous sibling of the element that is being hovered on (that is, the element with class='newsline')
• 它反过来是被悬空的元素的前一个兄弟元素(即具有class='newsline'的元素)

If you have any extra elements in between the element with class='newsline' and the container (with class='box-head') of the icon, the use the below jQuery selector instead.

如果在具有class='newsline'的元素和图标的容器(具有class='box-head')之间有任何额外的元素，可以使用下面的jQuery选择器。

$(this).prevAll('.box-head:first').children('.animated-div')

I have taken hover as a sample for both CSS and jQuery approaches but the same can be applied to the other pseudo-selectors like active, focus also.

我已经将鼠标悬停作为CSS和jQuery方法的示例，但同样也可以应用于其他伪选择器，比如active, focus。
