How do I make CSS hover transitions animate on mouse off AND mouse over, and replicate that in jQuery?

Tags: jquery,css3,css-transitions

Problem :

I am using CSS transitions to animate a background colour on mouse hover.

I have the following code:




div {
    width: 100px;
    height: 100px;  
    background: red;

div:hover {
    background: green;
    transition: all 0.5s ease-in-out;

This code only animates the background colour on mouse on. It doesn't reanimate the mouse off. I have 2 questions:

  1. How do I animate the mouse off using CSS?

  2. How do I do this using jQuery only?


Please excuse my bad English.

Solution :

1) You change your css to

div {
    width: 100px;
    height: 100px;  
    background: red;
    transition: background 0.5s ease-in-out;

div:hover {
    background: green;



setting the transition to the element, and not the pseudo class.


With jQuery you'll either need two elements to cross fade, or a color animation plugin. jQuery UI has color animation built in, and then you can do :

    mouseenter: function() {
        $(this).animate({backgroundColor: 'green'},1000)
    mouseleave: function() {
        $(this).animate({backgroundColor: 'red'},1000)


If you're not already using jQuery UI for something else, I'd suggest using one of the much smaller plugins, like this one !!
