The special writing _javascript technique of JavaScript css float property

1, for no underlined CSS properties are generally directly using style. Property name.
such as: Obj.style.margin,obj.style.width,obj.style.left,obj.style.position and so on.

2, for the CSS attribute with the underline, remove each underline and capitalize the first character after each underline.
such as: Obj.style.margintop,obj.style.borderleftwidth,obj.style.zindex,obj.style.fontfamily and so on.

This rule I think most front-end developers are also familiar with. There is a special attribute in CSS for its JS use method is very special.
This particular property is: float. We cannot use obj.style.float directly, so the operation is invalid.
The correct way to use it is: (IE, Opera): Obj.style.styleFloat, other browsers (Firefox): obj.style.cssFloat
