CSS Question

hover page background change color fade effect (css or jquery)

I have tried to figure out to let the background color fade when changing. But fail to do so. Not sure whether I should use css or jqeury. Please have a look, thank you.

.wrapper {
width: 100%;

.right-col {
width: 50%;
float: left;

a.btn {
background: #fff;
display: inline-block;

a.btn:before {
background-color: transparent;
transition: all 0.5s ease;
-webkit-transition: all 0.5s ease;
-moz-transition: all 0.5s ease;
-ms-transition: all 0.5s ease;
-o-transition: all 0.5s ease;

a.btn:hover:before {
content: '';
position: fixed;
display: block;
top: 0;
bottom: 0;
left: 0;
right: 0;
z-index: -1;

a.btn.btn-1:hover:before {
background-color: red;

a.btn.btn-2:hover:before {
background-color: green;

<div class="wrapper">
<div class="left-col">
<a href="#" class="btn btn-1">Button 1</a>
<div class="right-col">
<a href="#" class="btn btn-2">Button 2</a>

Update the jquery fiddle here:
It's working now, but the place that I hover is not accurate.
It keep on showing green even I didn't hover anything.


background-color is a CSS transitionable/animatable property.

All I did was set the transition, and used JQuery to add/remove some classes causing the background color of that element to change.

Have a look at my CodePen here:


  <h1>Mouse over a color</h1>
  <div class="blue">Blue</div>
  <div class="green">Green</div>


  background-color: red;
  transition: background-color 4s;

  background-color: blue;

  background-color: green;
