<a-toaster> — a viewport-anchored notification region. One instance hosts all
six placement zones; each <a-toast> routes to a corner/edge by its slot
attribute (slot="bottom-right", …). The <Toaster> wrapper keeps it mounted
and renders its <a-toast> children through the reconciler; this element only
lays them out — it touches its own shadow and reads its children, never a host
or light-DOM write.
Shadow structure:
← top-layer, viewport-covering, click-through
… ← one flex column per zone, pinned to its edge
…
The region is a popover so it renders in the top layer and escapes any
transformed / clipping ancestor of wherever <Toaster> is mounted. It's shown
only while it holds at least one toast (showPopover) and hidden when empty
(hidePopover), so it never sits in the top layer for nothing. Natural
top-layer ordering stands: a dialog or menu opened afterward can cover it (by
design — toasts don't force themselves above modals).
The Element.attributes property returns a live collection of all attribute nodes registered to the specified node. It is a NamedNodeMap, not an Array, so it has no Array methods and the Attr nodes' indexes may differ among browsers. To be more specific, attributes is a key/value pair of strings that represents any information regarding that attribute.
The clientHeight read-only property of the Element interface is zero for elements with no CSS or inline layout boxes; otherwise, it's the inner height of an element in pixels. It includes padding but excludes borders, margins, and horizontal scrollbars (if present).
The clientLeft read-only property of the Element interface returns the width of the left border of an element in pixels. It includes the width of the vertical scrollbar if the text direction of the element is right-to-left and if there is an overflow causing a left vertical scrollbar to be rendered. clientLeft does not include the left margin or the left padding.
The clientWidth read-only property of the Element interface is zero for inline elements and elements with no CSS; otherwise, it's the inner width of an element in pixels. It includes padding but excludes borders, margins, and vertical scrollbars (if present).
The currentCSSZoom read-only property of the Element interface provides the "effective" CSS zoom of an element, taking into account the zoom applied to the element and all its parent elements.
The innerHTML property of the Element interface gets or sets the HTML or XML markup contained within the element, omitting any shadow roots in both cases.
The outerHTML attribute of the Element interface gets or sets the HTML or XML markup of the element and its descendants, omitting any shadow roots in both cases.
The scrollHeight read-only property of the Element interface is a measurement of the height of an element's content, including content not visible on the screen due to overflow.
The scrollLeft property of the Element interface gets or sets the number of pixels by which an element's content is scrolled from its left edge. This value is subpixel precise in modern browsers, meaning that it isn't necessarily a whole number.
The scrollTop property of the Element interface gets or sets the number of pixels by which an element's content is scrolled from its top edge. This value is subpixel precise in modern browsers, meaning that it isn't necessarily a whole number.
The scrollWidth read-only property of the Element interface is a measurement of the width of an element's content, including content not visible on the screen due to overflow.
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.
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:
The autocorrect property of the HTMLElement interface controls whether or not autocorrection of editable text is enabled for spelling and/or punctuation errors.
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.
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.
The offsetHeight read-only property of the HTMLElement interface returns the height of an element, including vertical padding and borders, as an integer.
The offsetLeft read-only property of the HTMLElement interface returns the number of pixels that the upper left corner of the current element is offset to the left within the HTMLElement.offsetParent node.
The HTMLElement.offsetParent read-only property returns a reference to the element which is the closest (nearest in the containment hierarchy) positioned ancestor element.
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.
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).
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.
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.
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.

The read-only nodeType property of a Node interface is an integer that identifies what the node is. It distinguishes different kinds of nodes from each other, such as elements, text, and comments.
The read-only parentElement property of Node interface returns the DOM node's parent Element, or null if the node either has no parent, or its parent isn't a DOM Element. Node.parentNode on the other hand returns any kind of parent, regardless of its type.
The read-only previousSibling property of the Node interface returns the node immediately preceding the specified one in its parent's childNodes list, or null if the specified node is the first in that list.
This element's own window (the iframe's window when nested).
Returns Window&typeofglobalThis
Protecteddoc
getdoc():Document
This element's own document (the iframe's document when nested).
Returns Document
classList
getclassList():DOMTokenList
The read-only classList property of the Element interface contains a live DOMTokenList collection representing the class attribute of the element. This can then be used to manipulate the class list.
The read-only part property of the Element interface contains a DOMTokenList object representing the part identifier(s) of the element. It reflects the element's part content attribute. These can be used to style parts of a shadow DOM, via the ::part pseudo-element.
The closest() method of the Element interface traverses the element and its parents (heading toward the document root) until it finds a node that matches the specified CSS selector.
The computedStyleMap() method of the Element interface returns a StylePropertyMapReadOnly interface which provides a read-only representation of a CSS declaration block that is an alternative to CSSStyleDeclaration.
The getAttributeNS() method of the Element interface returns the string value of the attribute with the specified namespace and name. If the named attribute does not exist, the value returned will either be null or "" (the empty string); see Notes for details.
The getAttributeNames() method of the Element interface returns the attribute names of the element as an Array of strings. If the element has no attributes it returns an empty array.

The getClientRects() method of the Element interface returns a collection of DOMRect objects that indicate the bounding rectangles for each CSS border box in a client.
The Element method getElementsByClassName() returns a live HTMLCollection which contains every descendant element which has the specified class name or names.
The Element.getElementsByTagNameNS() method returns a live HTMLCollection of elements with the given tag name belonging to the given namespace. It is similar to Document.getElementsByTagNameNS, except that its search is restricted to descendants of the specified element.
The hasAttributeNS() method of the Element interface returns a boolean value indicating whether the current element has the specified attribute with the specified namespace.
The hasPointerCapture() method of the Element interface checks whether the element on which it is invoked has pointer capture for the pointer identified by the given pointer ID.
The insertAdjacentElement() method of the Element interface inserts a given element node at a given position relative to the element it is invoked upon.
The insertAdjacentHTML() method of the Element interface parses the specified input as HTML or XML and inserts the resulting nodes into the DOM tree at a specified position.
The insertAdjacentText() method of the Element interface, given a relative position and a string, inserts a new text node at the given position relative to the element it is called from.
The releasePointerCapture() method of the Element interface releases (stops) pointer capture that was previously set for a specific (PointerEvent) pointer.
The Element interface's scrollIntoView() method scrolls the element's ancestor containers such that the element on which scrollIntoView() is called is visible to the user.
The setAttribute() method of the Element interface sets the value of an attribute on the specified element. If the attribute already exists, the value is updated; otherwise a new attribute is added with the specified name and value.
The setHTMLUnsafe() method of the Element interface is used to parse HTML input into a DocumentFragment, optionally filtering out unwanted elements and attributes, and those that don't belong in the context, and then using it to replace the element's subtree in the DOM.
The setPointerCapture() method of the Element interface is used to designate a specific element as the capture target of future pointer events. Subsequent events for the pointer will be targeted at the capture element until capture is released (via Element.releasePointerCapture() or the pointerup event is fired).
The toggleAttribute() method of the Element interface toggles a Boolean attribute (removing it if it is present and adding it if it is not present) on the given element.
The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) also apply to events dispatched manually with dispatchEvent().
The HTMLElement.attachInternals() method returns an ElementInternals object. This method allows a custom element to participate in HTML forms. The ElementInternals interface provides utilities for working with these elements in the same way you would work with any standard HTML form element, and also exposes the Accessibility Object Model to the element.
The HTMLElement.click() method simulates a mouse click on an element. When called on an element, the element's click event is fired (unless its disabled attribute is set).
The hidePopover() method of the HTMLElement interface hides a popover element (i.e., one that has a valid popover attribute) by removing it from the top layer and styling it with display: none.
The showPopover() method of the HTMLElement interface shows a popover element (i.e., one that has a valid popover attribute) by adding it to the top layer.
The togglePopover() method of the HTMLElement interface toggles a popover element (i.e., one that has a valid popover attribute) between the hidden and showing states.
The cloneNode() method of the Node interface returns a duplicate of the node on which this method was called. Its parameter controls if the subtree contained in the node is also cloned or not.
The contains() method of the Node interface returns a boolean value indicating whether a node is a descendant of a given node, that is the node itself, one of its direct children (childNodes), one of the children's direct children, and so on.
The isDefaultNamespace() method of the Node interface accepts a namespace URI as an argument. It returns a boolean value that is true if the namespace is the default namespace on the given node and false if not. The default namespace can be retrieved with Node.lookupNamespaceURI() by passing null as the argument.
The isEqualNode() method of the Node interface tests whether two nodes are equal. Two nodes are equal when they have the same type, defining characteristics (for elements, this would be their ID, number of children, and so forth), its attributes match, and so on. The specific set of data points that must match varies depending on the types of the nodes.
The isSameNode() method of the Node interface is a legacy alias the for the === strict equality operator. That is, it tests whether two nodes are the same (in other words, whether they reference the same object).
The lookupNamespaceURI() method of the Node interface takes a prefix as parameter and returns the namespace URI associated with it on the given node if found (and null if not). This method's existence allows Node objects to be passed as a namespace resolver to XPathEvaluator.createExpression() and XPathEvaluator.evaluate().
The lookupPrefix() method of the Node interface returns a string containing the prefix for a given namespace URI, if present, and null if not. When multiple prefixes are possible, the first prefix is returned.
The normalize() method of the Node interface puts the specified node and all of its sub-tree into a normalized form. In a normalized sub-tree, no text nodes in the sub-tree are empty and there are no adjacent text nodes.
