使用CSS动画应用悬停缓动效果

Question

On this LIVE DEMO you can see how animation works in each div moves its image and gives opacity:1 to text.

When hover-off, naturally all styles get back to their initial state directly, but I want them to do it smoothly(ease), instead of setting all initial styles at the same time with no progress.

Here it is related animation code:

#highlights div[class*="high-"]:hover > p {
    -webkit-animation:downOp 0.3s ease-in 0s forwards;
    -ms-animation:downOp 0.3s ease-in 0s forwards;
    animation:downOp 0.3s ease-in 0s forwards;
}
#highlights div[class*="high-"]:hover > .image {
    -webkit-animation:imgTrans 5s ease-out 0s forwards;
    -ms-animation:imgTrans 5s ease-out 0s forwards;
    animation:imgTrans 5s ease-out 0s forwards;
}
@-webkit-keyframes downOp {
    0% {
        opacity:0.7;
    }
    100% {
        opacity:1;
    }
}
@-ms-keyframes downOp {
    0% {
        opacity:0.7;
    }
    100% {
        opacity:1;
    }
}
@keyframes downOp {
    0% {
        opacity:0.7;
    }
    100% {
        opacity:1;
    }
}
@-webkit-keyframes imgTrans {
    0% {
        margin-right: 0;
    }
    100% {
        margin-right: -50px;
    }
}
@-ms-keyframes imgTrans {
    0% {
        margin-right: 0;
    }
    100% {
        margin-right: -50px;
    }
}
@keyframes imgTrans {
    0% {
        margin-right: 0;
    }
    100% {
        margin-right: -50px;

} }

Answer 1

Everything remains same just add transition to p and image element.

#highlights .image {
    height:100%;
    -webkit-transition: all 0.5s ease; // increase 0.5s to whatever you wish in order to add more smoothness
    -moz-transition: all 0.5s ease;
    -ms-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}

#highlights p {
    background-color: white;
    bottom: 0;
    height: 60px;
    margin-bottom: 0px;
    position: absolute;
    opacity:0.7;
    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -ms-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}

Use css transform instead of css animation ! It will automatically handle hover-out effect!

            <br> <span>Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod</span>

        </p>
    </div>
