Answer 1

Add and remove a property named "color":

$(document).ready(function(){
    $("button").click(function(){
        var $x = $("div");
        $x.prop("color", "FF0000");
        $x.append("The color property has the following value: " + $x.prop("color"));
        $x.removeProp("color");
        $x.append("<br>Now the color property has the following value: " + $x.prop("color"));
    });
});
