Why is line 5 in the following code block giving me a Invalid value

Why is line 5 in the following code block giving me a “Invalid value for property: zoom” error? I am running it in Opera 11.62 and catching the error in Dragonfly.

    Internet Explorer 5.5 and above support the non-standard zoom CSS property. It sets the magnification scale of an element.

    There’s no CSS3 equivalent to this property yet.

    So you have an error in Opera because it doesn’t know about such property. This property is for IE only.

    In your case this Opera console error is produced by jQuery library – jQuery knows about zoom property and tries to use it.

    Here you can find more detailed description of this problem and also browsers compatibility table for zoom property.
