Properties
accessKey
The HTMLElement.accessKey property sets the keystroke which a user can press to jump to a given element.
ReadonlyaccessKeyLabel
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.

ReadonlyATTRIBUTE_NODE
Readonlyattributes
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.
ReadonlyattributeStyleMap
autocapitalize
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:
autocorrect
The autocorrect property of the HTMLElement interface controls whether or not autocorrection of editable text is enabled for spelling and/or punctuation errors.
autofocus
ReadonlybaseURI
The read-only baseURI property of the Node interface returns the absolute base URL of the document containing the node.
ReadonlyCDATA_SECTION_NODE
node is a CDATASection node.
ReadonlychildElementCount
ReadonlychildNodes
The read-only childNodes property of the Node interface returns a live NodeList of child nodes of the given element where the first child node is assigned index 0. Child nodes include elements, text and comments.
Readonlychildren
Returns the child elements.
className
The className property of the Element interface gets and sets the value of the class attribute of the specified element.
ReadonlyclientHeight
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).
ReadonlyclientLeft
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.
ReadonlyclientTop
The clientTop read-only property of the Element interface returns the width of the top border of an element in pixels.
ReadonlyclientWidth
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).
ReadonlyCOMMENT_NODE
node is a Comment node.
contentEditable
ReadonlycurrentCSSZoom
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.
ReadonlycustomElementRegistry
Readonlydataset
dir
The HTMLElement.dir property indicates the text writing directionality of the content of the current element. It reflects the element's dir attribute.
disabled
The disabled property of the HTMLFieldSetElement interface is a boolean value that reflects the
ReadonlyDOCUMENT_FRAGMENT_NODE
node is a DocumentFragment node.
ReadonlyDOCUMENT_NODE
node is a document.
ReadonlyDOCUMENT_POSITION_CONTAINED_BY
Set when other is a descendant of node.
ReadonlyDOCUMENT_POSITION_CONTAINS
Set when other is an ancestor of node.
ReadonlyDOCUMENT_POSITION_DISCONNECTED
Set when node and other are not in the same tree.
ReadonlyDOCUMENT_POSITION_FOLLOWING
Set when other is following node.
ReadonlyDOCUMENT_POSITION_IMPLEMENTATION_SPECIFIC
ReadonlyDOCUMENT_POSITION_PRECEDING
Set when other is preceding node.
ReadonlyDOCUMENT_TYPE_NODE
node is a doctype.
draggable
The draggable property of the HTMLElement interface gets and sets a Boolean primitive indicating if the element is draggable.
ReadonlyELEMENT_NODE
node is an element.
Readonlyelements
The elements read-only property of the HTMLFieldSetElement interface returns an HTMLCollection object containing all form control elements (
The
HTMLFieldSetElementinterface provides special properties and methods (beyond the regular HTMLElement interface it also has available to it by inheritance) for manipulating the layout and presentation of
