We also recommend you to use a Java Script library to extend and enhance the default form validation functionalities for better user experiences on modern web design.
In this post, you’ll find a list of 7 best and most downloaded Java Script Form Validation libraries (without any 3rd dependencies such as j Query) to validate your HTML form with custom error messages, CSS styles, validation rules and more.
