In web applications, forms are used to gather user input and pass it over to the server for further processing. During the process of user input, you need to validate form fields for the user's convenience.
Validating an HTML form is NOT a simple task as you develop a modern web app.
In general, most develops are using the Native HTML5 Form Validation to validate the HTML form with native browser experience.
But it is NOT enough.
For better user experience, custom styles, error messages and validation rules must be taken into account.
