The CSS Object Model is a set of APIs allowing the manipulation of CSS from JavaScript. It is much like the DOM, but for the CSS rather than the HTML. It allows users to read and modify CSS style dynamically.


Several other interfaces are also extended by the CSSOM-related specifications: Document, Window, Element, HTMLElement, HTMLImageElement, Range, MouseEvent, and SVGElement.

Browser compatibility notes

All these features have been added little by little over the years to the different browsers: it was a quite complex process that can't be summarized in a simple table. Please refer to the specific interfaces for its availability.
