使用css将鼠标悬停在另外两个元素上时动画化元素

Question

i am trying to animate a div when hovering on another div. Ihave following code

html

<div>
</div>
<div class="content">
</div>

css

div {
    height: 100px;
    width: 100px;
    background: red; 
        transition: all 0.4s ease-in-out;
}
.content {
    height: 20px;
    width: 20px;
    background: green;
    display: none;

}
div:hover + .content{
    display: block;
    margin-top: -100px;
    margin-left: 50px;
}

What i am trying to do is, i need to animate .content to margin-top: -100px and margin-left: 50px; from its default position, when the user is hover on one of these elements. But atm with this code it only works when the user hover on the .content and it animate the other way. (from margin-top: -100px and margin-left: 50px; to default position). Please excuse my english

You need to wrap the content in the div and use a child selector. Note I gave the larger div an id as well. Here is the css:

JS Fiddle

#box {
    height: 100px;
    width: 100px;
    background: red;
    position: absolute;
    transition: all 0.4s ease-in-out;
}
#content {
    width: 20px;
    background: green;
    height: 0;
    transition: all 0.4s ease-in-out;
    position: margin-top: -100px;
    margin-left: 50px;
    -webkit-transition: all .8s ease;
    -moz-transition: all .8s ease;
    -ms-transition: all .8s ease;
    -o-transition: all .8s ease;
    transition: all .8s ease;
}
#box:hover > #content {
    height: 20px;
}
