How to style checkbox using CSS?

There is a way to do this using just css. We can (ab)use the label element and style that instead. The caveat is that this will not work for IE8 and lower versions.

CSS:

.myCheckbox input {
    display: none;
}

.myCheckbox span {
    width: 20px;
    height: 20px;
    display: block;
    background: url("link_to_image");
}

.myCheckbox input:checked + span {
    background: url("link_to_another_image");
}

HTML:

<label for="test">Label for my styled "checkbox"</label>
<label class="myCheckbox">
    <input type="checkbox" name="test"/>
    <span></span>
</label>

Warning: the following was true at the time of writing, but in the meantime things have progressed.

AFAIK modern browsers display checkboxes using the native OS control, so there's no way to style them.

I think the easiest way to do it is by styling a label and making the check-box invisible.

HTML

<input type="checkbox" id="first" />
<label for="first">&nbsp;</label>

CSS

checkbox{
display:none;
}

checkbox + label{
/*Style for checkbox normal*/
width:16px;
height:16px;
}

checkbox::checked + label, label.checked{
/*Style for checkbox checked*/
}

the checkbox even though it is hidden will still be accessible and it's value will be sent when a form is submitted. For old browsers you might have to change the class of the label to checked using JavaScript because I don't think old versions of IE understand ::checked on the checkbox

this the checkbox like with iPhone, it it used the pure css3 to create,pls view the tutorial:http://www.w3cplus.com/css3/css3-style-iphone-checkbox

You can achieve quite a cool custom checkbox effect by using the new abilities that come with the :after and :before psuedo classes. The advantage to this, is: You don't need to add anything more to the dom, just the standard checkbox.

Note this will only work for compatible browsers, which unfortunately at the moment appears to be webkit only, but I am sure FF + IE, will work in the future (as no prefixes used) :)
