Since it is not possible to recurse when using a regular expression it is also not possible to create a truly accurate regex for doing email address validation.The value, clicking 'down' with the input blank will result in a very large number. The examples posted in these responses are vastly oversimplified when compared against reality.We have a separate article with details on validating passwords using HTML5, including Java Script code for customising the browser generated alert messages.

In this article we intend to present only a number of simple examples to get you started, covering the basic form elements.There's no need to copy any images and, especially if your style-sheets are gzip-compressed, there will be next to no impact on load times. The main problem is that if the user doesn't enter a new value, the placeholder text will be submitted along with the form.In a few minutes you could have your whole website updated. I would highly recommend using one the various placeholder polyfill scripts if you want to support the placeholder attribute in older browsers: e.g.The simplest change you can make to your forms is to mark a text input field as 'required': This informs the (HTML5-aware) web browser that the field is to be considered mandatory.Different browsers may mark the input box in some way (Firefox 4 Beta adds a red box-shadow by default), display a warning (Opera) or even prevent the form from being submitted if this field has no value.
