Consider using CSSOM to manage styles

[davletovalmir]

Currently, styles are not on par with CSSOM standards. The test below would fail:

const node = document.createElement('div');
node.style.backgroundColor = "#ffa015";
expect(node.style.backgroundColor).toEqual("rgb(255, 160, 21)"); // <-- will fail here

Though it sounds like node.style.backgroundColor should return "#ffa015", according to the specs, it must convert hexadecimal values to rgb format.
