 An object of this type has dash-named properties for **all** [CSS properties](/en-US/docs/Web/CSS/Properties) supported by the browser, including both [shorthand](/en-US/docs/Web/CSS/CSS_cascade/Shorthand_properties) and longhand properties, and those with `-moz` and `-webkit` prefixes.

+These can accessed using methods inherited from the {{DOMxRef("CSSStyleDeclaration")}} base class, such as {{DOMxRef("CSSStyleDeclaration/getPropertyPriority", "getPropertyValue()")}} and {{DOMxRef("CSSStyleDeclaration/getPropertyPriority", "setPropertyValue()")}}.
 
 In addition, each dash-cased property has a corresponding {{glossary("camel case")}}-named property, where the name is generated by removing the dashes and capitalizing each word after the first one.
 This allows you to, for example, access the `margin-top` CSS property using the syntax `style.marginTop` (where `style` is a `CSSStyleProperties`), instead of the more cumbersome `style.getPropertyValue("margin-top")` or `style["margin-top"]`.
