In the post Using Modernizr, Polyfills, YepNope, you learned how you can support browsers that might not have the capabilities that you need. But at some point you may not be able to support really old browsers. At that point, you may just want to recommend the user update. Even for enterprise apps, you will want to remind users to use a current browser rather than have your app fail because your app is expecting something that does not exist.>p>You can use the following code to help your users get up to date browsers.

HTML5 Tutorial – HTML Forms Tags


One of the cool features of HTML5 is the support offered in forms. You’ve probably worked with HTML form tag, which is how you collect customer responses and add interactivity to your website.
