Many developers build custom form controls, either to provide controls that aren't built in to the browser, or to customize the look and feel beyond what's possible with the built-in form controls. However, it can be difficult to replicate the features of built-in HTML form controls. Consider some of the features an <input> element gets automatically when you add it to a form: The input is automatically added to the form's list of controls. The input's value is automatically submitted with the form. The input participates in form validation. You can style the input using the :valid and :invalid pseudoclasses. The input is notified when the form is reset, when the form is reloaded, or when the browser tries to autofill form entries. Custom form controls typically have few of these features. Developers can work around some of the limitations in JavaScript, like adding a hidden <input> to a form to participate in form submission. But other features just can't be replicated in JavaScript alone. Two new web features make it easier to build custom form controls, and remove the limitations of current custom controls: The formdata event lets an arbitrary JavaScript object participate in form submission, so you can add form data without using a hidden <input>. The Form-associated custom elements API lets custom elements act more like built-in form controls. These two features can be used to create new kinds of controls that work better.",
