How Can I Customize HTML5 Form Validation Popups?

Customizing HTML5 Form Validation Popups

When utilizing HTML5 forms, the default validation popups can sometimes be unsatisfactory. However, it's crucial to note that it's impossible to alter the validation style using only HTML and CSS.

The default popup is an inherent part of the browser itself. The only attribute you can modify is the error message, which can be set using:

document.getElementById("name").setCustomValidity("Lorum Ipsum");

For an alternative solution, consider using jQuery. The Webshims library (https://github.com/jquery/webshim) provides a method for overriding the panel style through CSS.

This ingenious approach allows you to customize the error panel UI, as demonstrated in this example: http://jsfiddle.net/trixta/qTV3g/.
