The CSSStyleDeclaration interface represents an object that is a CSS declaration block, and exposes style information and various style-related methods and properties.
A CSSStyleDeclaration object can be exposed using three different APIs:
HTMLElement.style, which deals with the inline styles of a single element (e.g., <div style="â¦">).CSSStyleSheet API. For example, document.styleSheets[0].cssRules[0].style returns a CSSStyleDeclaration object on the first CSS rule in the document's first stylesheet.Window.getComputedStyle(), which exposes the CSSStyleDeclaration object as a read-only interface.CSSStyleDeclaration.cssText
Textual representation of the declaration block, if and only if it is exposed via HTMLElement.style. Setting this attribute changes the inline style. If you want a text representation of a computed declaration block, you can get it with JSON.stringify().

CSSStyleDeclaration.parentRule Read only
