HTML Concepts: Form Owners

Post from December 18, 2021, filed under .

Today in “HTML Concepts”: form owners. It’s not what you are when you put a form on a page.

What are form owners? In essence, form elements that so-called form-associated elements are tied to.

Form-associated elements are the following:

button, fieldset, input, object, output, select, textarea, img, as well as form-associated custom elements.

(These fall into certain categories, namely listed, submittable, resettable, and autocapitalize-inheriting elements.)

Form ownership is straightforward, as the connection of a form-associated element with a form owner is simple:

The element is associated with its nearest ancestor form element—unless it is a form-associated listed element (anything not img) and has a form attribute that overrides this association. (One can construct scenarios in which neither is the case.)

In many cases one can say that each form element has a form owner, its parent form element. (And you, if you own a web form, can still call yourself a form owner, too.)
