getElementsByTagNameNS(namespaceURI: "http://www.w3.org/2000/svg", localName: string): HTMLCollectionOf<SVGElement>

getElementsByTagNameNS(namespaceURI: string, localName: string): HTMLCollectionOf<Element>

hasAttribute(qualifiedName: string): boolean

Returns true if element has an attribute whose qualified name is qualifiedName, and false otherwise.

hasAttributeNS(namespace: string | null, localName: string): boolean

Returns true if element has an attribute whose namespace is namespace and local name is localName.

hasAttributes(): boolean

Returns true if element has attributes, and false otherwise.

hasPointerCapture(pointerId: number): boolean

insertAdjacentElement(position: InsertPosition, insertedElement: Element): Element | null

insertAdjacentHTML(where: InsertPosition, html: string): void

insertAdjacentText(where: InsertPosition, text: string): void

matches(selectors: string): boolean

requestFullscreen(options?: FullscreenOptions): Promise<void>

Displays element fullscreen and resolves promise when done.

When supplied, options's navigationUI member indicates whether showing navigation UI while in fullscreen is preferred or not. If set to "show", navigation simplicity is preferred over screen space, and if set to "hide", more screen space is preferred. User agents are always free to honor user preference over the application's. The default value "auto" indicates no application preference.

scrollTo(options?: ScrollToOptions): void

scrollTo(x: number, y: number): void

setAttribute(qualifiedName: string, value: string): void

Sets the value of element's first attribute whose qualified name is qualifiedName to value.

setAttributeNS(
