HTML5 and older browser support using a polyfill

I know most people want to get into using HTML5 and reap the massive benefits it has to offer but most people dont have the choice to migrate to HTML5 because of the restrictions of older browsers, I found an interesting article of stackoverflow that others may want to read before setting out using a polyfill: http://stackoverflow.com/questions/9067536/html5-forms-with-polyfills-is-it-worth-it.

You can easily mimic the support of HTML5 using javascript and a small polyfill called webshims, you can find it here:

Once you've downloaded webshims and added it into your website, you'll be able to use all the featured of HTML5 without worrying about older browsers and their unrelenting need for effort in your part and if you need help implementing webshims then take a look at the source of the page above, it'll show you everything you need to know.
