DOM manipulating CSS

1 inline-style operations
Syntax for DOM manipulation of a style property:
CSS Style Properties DOM notation
Background-color Node.style.backgroundColor
Color Node.style.color
Font Node.style.font
Font-family node.style.fontFamily
For browser compatibility, the following is the wording:
Node.style.webkitTransform = ""; More important common
Node.style.MozTransform = "";
Node.style.msTransform = "";
Node.style.OTransform = "";
Node.style.transform = "";

2 Working with style sheets
Get the code for the style sheet as follows:
var cssrules = Document.stylesheets[0].cssrules | | Document.stylesheets[0].rules;
Note: IE is a collection of rules, whereas a browser that follows the DOM specification is the cssrules used.

3 Getting the final style
3.1 Get the final style under IE browser
var Divele = document.getElementById ("divID");
var backgroundcolor = DivEle.currentStyle.backgroundColor;
3.2 Getting the final style under a DOM-compliant browser
var Divele = document.getElementById ("divID");
var backgroundcolor = Document.defaultView.getComputedStyle (Divele, null). BackgroundColor;
Of course I can write that.
window.getComputedStyle (Divele, NULL);//Obviously this is more convenient because window can not write
