IE8 screenshot (error): 
Google Chrome Screenshot (how it should look): 
The current checkbox was created using CSS3, is there any way to make it compatible?
Checking the box We did in JSFiddle, this is part of the CSS3 technique, so the lower browser cannot display some of them, why. Please check the form on IE Tester (which you can download and test a lower version of IE if you are using Windows) and you will see what I mean.

<p> <label></label> <input type="checkbox" id="checkbox" name="checkbox" class="regular-checkbox big-checkbox" value="Yes" checked="checked"> <label for="checkbox" style="margin-right:10px;"></label>Subscribe me to your mailing list for upcoming events, hot offers and deals </p>
Note. We also used Dropkick (jQuery), which selects only styles but does not check the box.
