abstract class NgElement extends HTMLElement {}
The strategy that controls how a component is transformed in a custom element. A subscription to change, connect, and disconnect events in the custom element. Prototype for a handler that responds to a change in an observed attribute. @paramattrNamestringThe name of the attribute that has changed. @paramoldValuestring | nullThe previous value of the attribute. @paramnewValuestringThe new value of the attribute. @paramnamespacestring | undefinedThe namespace in which the attribute is defined. Prototype for a handler that responds to the insertion of the custom element in the DOM. Prototype for a handler that responds to the deletion of the custom element from the DOM. The HTMLElement.accessKey property sets the keystroke which a user can press to jump to a given element.
MDN Reference The HTMLElement.accessKeyLabel read-only property returns a string containing the element's browser-assigned access key (if any); otherwise it returns an empty string.
MDN Reference The autocapitalize property of the HTMLElement interface represents the element's capitalization behavior for user input. It is available on all HTML elements, though it doesn't affect all of them, including:
MDN Reference The autocorrect property of the HTMLElement interface controls whether or not autocorrection of editable text is enabled for spelling and/or punctuation errors.
MDN Reference The HTMLElement.dir property indicates the text writing directionality of the content of the current element. It reflects the element's dir attribute.
MDN Reference The draggable property of the HTMLElement interface gets and sets a Boolean primitive indicating if the element is draggable.
MDN Reference The HTMLElement property hidden reflects the value of the element's hidden attribute.
MDN Reference The HTMLElement property inert reflects the value of the element's inert attribute. It is a boolean value that, when present, makes the browser "ignore" user input events for the element, including focus events and events from assistive technologies. The browser may also ignore page search and text selection in the element. This can be useful when building UIs such as modals where you would want to "trap" the focus inside the modal when it's visible.
MDN Reference The innerText property of the HTMLElement interface represents the rendered text content of a node and its descendants.
MDN Reference The lang property of the HTMLElement interface indicates the base language of an element's attribute values and text content, in the form of a BCP 47 language tag. It reflects the element's lang attribute; the xml:lang attribute does not affect this property.

MDN Reference The offsetTop read-only property of the HTMLElement interface returns the distance from the outer border of the current element (including its margin) to the top padding edge of the offsetParent, the closest positioned ancestor element.
MDN Reference The offsetWidth read-only property of the HTMLElement interface returns the layout width of an element as an integer.
MDN Reference The outerText property of the HTMLElement interface returns the same value as HTMLElement.innerText. When used as a setter it replaces the whole current node with the given text (this differs from innerText, which replaces the content inside the current node).
MDN Reference The popover property of the HTMLElement interface gets and sets an element's popover state via JavaScript ("auto", "hint", or "manual"), and can be used for feature detection.
MDN Reference The spellcheck property of the HTMLElement interface represents a boolean value that controls the spell-checking hint. It is available on all HTML elements, though it doesn't affect all of them.

MDN Reference The translate property of the HTMLElement interface indicates whether an element's attribute values and the values of its Text node children are to be translated when the page is localized, or whether to leave them unchanged.
MDN Reference The writingSuggestions property of the HTMLElement interface is a string indicating if browser-provided writing suggestions should be enabled under the scope of the element or not.
MDN Reference The HTMLElement.attachInternals() method returns an ElementInternals object. This method allows a custom element to participate in HTML forms.

MDN Reference The clientTop read-only property of the Element interface returns the width of the top border of an element in pixels.
