I am trying to change the default \'box image\' of the checkbox with CSS, but it is not working. Is there any way around this?

You can use pure css, just add a label to the checkbox like this:

.check_box {
    display:none;
}

.check_box + label{
    background:url('images/check-box.png') no-repeat;
    height: 16px;
    width: 16px;
    display:inline-block;
    padding: 0 0 0 0px;
}

.check_box:checked + label{
    background:url('images/check-box-checked.png') no-repeat;
    height: 16px;
    width: 16px;
    display:inline-block;
    padding: 0 0 0 0px;
}

Example HTML:

    .check_box {
    	display:none;
    }

    .check_box + label{
    	background:url('images/check-box.png') no-repeat;
    	height: 16px;
    	width: 16px;
    	display:inline-block;
        padding: 0 0 0 0px;
    }

    .check_box:checked + label{
        background:url('images/check-box-checked.png') no-repeat;
    	height: 16px;
    	width: 16px;
    	display:inline-block;
        padding: 0 0 0 0px;
    }

<input type="checkbox" class="check_box" id="checkbox1">
<label for="checkbox1">

Try:

<input type="checkbox" class="input_class_checkbox">

jQuery

$('.input_class_checkbox').each(function(){
    $(this).hide().after('<div class="class_checkbox" />');

});

$('.class_checkbox').on('click',function(){
    $(this).toggleClass('checked').prev().prop('checked',$(this).is('.checked'))
});

Fiddle: http://jsfiddle.net/cn6kn/

$('.input_class_checkbox').each(function(){
    $(this).hide().after('<div class="class_checkbox" />');

});

$('.class_checkbox').on('click',function(){
    $(this).toggleClass('checked').prev().prop('checked',$(this).is('.checked'))
});

.class_checkbox {
    width: 20px;  
    height: 20px;
    background-color: red;
}
.class_checkbox.checked {
    background-color: green;
}

<input type="checkbox" class="input_class_checkbox">

I created a Fiddle using pure CSS. The most voted answer doesn't handle click events and won't work well, because the checkbox value won't change.

This is my example:

http://jsfiddle.net/kEHGN/1/

Basically, we need the following html:

<div class="checkbox_wrapper">
    <input type="checkbox" />
    <label></label>
</div>

And the following CSS:

.checkbox_wrapper{
    position: relative;
    height: 16px;
    width: 17px;
}

input[type="checkbox"] {
    opacity:0;
    height: 16px;
    width: 17px;
    position: absolute;
    top: 0;
    left: 0;
    z-index: 2;
}

input[type="checkbox"] + label{
    background:url('../images/unchecked.png') no-repeat;
    height: 16px;
    width: 17px;
    display:inline-block;
    padding: 0 0 0 0px;
    position: absolute;
    top: 0;
    left: 0;
    z-index: 1;
}

input[type="checkbox"]:checked + label{
    background:url('../images/checked.png') no-repeat;
    height: 16px;
    width: 17px;
    display:inline-block;
    padding: 0 0 0 0px;
}

Just check the routes of the images, and the widths and heights should be equal to the width and height of the images. On the fiddler I am using base64 encoded images.

I hope it can be useful.

I found another way, without using adjacent labels or surrounding divs.

My usecase was that I had a markdown parser that generates those nifty TODO lists and I wanted to style them. Changing the generated HTML wasn't a option, so I came up with this solution:

given a checkbox like this:
```
<input type="checkbox" id="cb">
```
You can style it with visibility: hidden on checkbox and visibility: visible on ::after, like this:
```
#cb {
  visibility: hidden;
}

input#cb::after {
  visibility: visible;
  content: "F";
  color: red;
  background: green;
  padding: 8px;
}

input#cb:checked::after {
  content: " T ";
  color: green;
  background: red;
}
```
```
<!doctype html>
<html>

<body>
  <input type="checkbox" id="cb">
</body>

</html>
```
EDIT:

@connexo in a comment pointed out that input elements cannot have content. It could be easly done using label element, for example like so (please someone correct me if this is wrong, I don't have non-webkit browser handy to test it).
```
#cb-span * {
  visibility: hidden;
}

input#cb + label::after {
  visibility: visible;
  content: "F";
  color: red;
  background: green;
  padding: 8px;
}

input#cb:checked + label::after {
  content: " T ";
  color: green;
  background: red;
}
```
```
<!doctype html>
<html>

<body>
  <span id="cb-span">
    <input type="checkbox" id="cb">
    <label for="cb"></label>
  </span>
</body>

</html>
```
The checkbox works just like normal one and you can style it anyway you like.

Maybe it'll help someody (and I can bookmark it, because I haven't found anything like this on the web)

Maybe will be useful my sample with LESS.

<div class="custom-checkbox">
    <input component="input" type="checkbox"/>
    <label>Here is caption right to checkbox</label>
</div>

    @imgsize: 25px;
    .custom-checkbox{
        position: relative;

        > input[type="checkbox"] {

        display:none;
        position: absolute;
        top: 0;
        left: 0;

            + label{

                background:url('../img/unchecked.png') no-repeat 0 0;
                background-size:@imgsize;
                height: @imgsize;
                padding: 4px 0 5px 35px;
                display: inline-block;
                -webkit-transition-duration: 0.3s;
                -moz-transition-duration: 0.3s;
                transition-duration: 0.3s;        
            }
        }
        > input[type="checkbox"]:checked + label{

            background:url('../img/checked.png') no-repeat;
            background-size:@imgsize @imgsize;
        }
    }
