Is it possible to get value of multiple CSS properties in single statement?

Well, before jQuery 1.9 release it was not possible but one of the new feature of jQuery 1.9 was .css() multi-property getter.

var propCollection = $("#dvBox").css(["width", "height", "backgroundColor"]);

In this case, the propCollection will be an array and it will look something like this.

{ 
  width: "100px", 
  height: "200px", 
  backgroundColor: "#FF00FF" 
}
