changing image during flip css animation - html

Question

I currently have a rotating image that flips around and has writing on the back using animated css, however what I want is that when the image flips around it changes with another image so it has a solid colour instead of a reversed version of the image.
CSS
.hover-img {
position: relative;
width: 400px;
height: 300px;
-webkit-transition: all 1s ease-in-out;
-moz-transition: all 1s ease-in-out;
-ms-transition: all 1s ease-in-out;
-o-transition: all 1s ease-in-out;
transition: all 1s ease-in-out;
background:url(bbclike/topright.png);
-webkit-transform:rotateY(180deg);
-webkit-transform-style: preserve-3d;
line-height:200px;
text-align:center;
font-size:0;
}
.hover-img:hover{
-webkit-transform:rotateY(0deg);
font-size:14px;
color:white;
background-color:#FF0;
}
HTML
<div class="hover-img">
Text Goes Here
</div>

Answer 1

Just put in hover section whatever you want when user hovers the div... E.g. :
.hover-img:hover{
background:url(---HERE IMAGE 2---);
font-size:14px;
color:white;
background-color:#FF0;
}

change the container class, so that you can manipulate DOM class.
//html
<div>
<i class="icon"></i>
</div>
<br>
<input class="button" type="button" value="flip">
//css
div{
}
.icon {
display: inline-block;
width: 30px;
height: 30px;
transition: all 0.5s;
}
div .icon {
background: url("https://www.w3schools.com/images/compatible_chrome.gif") no-repeat;
}
div.ie .icon{
background: url("https://www.w3schools.com/images/compatible_edge.gif") no-repeat;
transform: scaleX(-1)
}
//javascript
$(".button").click(function() {
$("div").toggleClass("ie");
});
Hope this will find you useful.
