RatingWidget’s core ratings script is supported on all modern browsers like Chrome, FireFox 3.0 and Higher, Safari, Opera and Internet Explore 7.0 and Higher.
But in order to make sure the ratings will work correctly on IE7, IE8 & IE9, please verify your HTML’s DOCTYPE declaration is set to XHTML 1.0 Strict. This directive instructs the browser to use the correct version of HTML RatingWidget should be render with.
If you already have a DOCTYPE declaration at your HTML document, simply replace it with:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
If you don’t have any DOCTYPE in your document, just add it before the <html> tag.
