The ShadowRoot interface of the Shadow DOM API is the root node of a DOM subtree that is rendered separately from a document's main DOM tree. You can retrieve a reference to an element's shadow root using its Element.
What you can see below #shadow-root is called “shadow DOM”. We can’t get built-in shadow DOM elements with regular JavaScript calls or selectors. These are not regular children but a strong technique for encapsulation. Shadow Root: A shadow tree is a node tree whose root called as a shadow root.
The shadow root, returned by attachShadow, is like an element: we can use innerHTML or DOM methods, such as append, to populate it. The element with a shadow root is called a “shadow tree host”, and is available as the shadow root host property: Shadow DOM elements are not visible to querySelector from the light DOM.
We can’t get built-in shadow DOM elements with regular JavaScript calls or selectors. These are not regular children but a strong technique for encapsulation. Shadow Root: A shadow tree is a node tree whose root called as a shadow root. A shadow root is always attached through its host to another node tree.
To get elements in shadow tree, we must query from inside the tree. Shadow DOM is mentioned in many other specifications, e.g. DOM Parsing specifies that shadow root has innerHTML. Shadow DOM is a way to create a component-local DOM. shadowRoot = elem.attachShadow ( {mode: open|closed}) – creates shadow DOM for elem.
You cannot access a Shadow DOM created by the browser to display a control, that is called a #shadow-root (user-agent) in the Dev Tools. <input> is one example.
You can only access open custom Shadow DOM (the ones that you create yourself), with the { mode: 'open' } option.
element.attachShadow( { mode: 'open' } )
Update
It's true for most UX standard HTML elements: <input>, <video>, <textarea>, <select>, <audio>, etc.
