I am trying to generate a random number for the css opacity.

This is what I tried so far.

CSS

.test{
    position : absolute;
    width : 15px;
    height : 15px;
    border-radius:15px;
    background-color : black; 
}?

Script

$(function() {
    for (var i = 0; i < 300; i++) {
        $("<div>", {
            class: "test",
            css: {
                opacity: randomOpacity
            }
        }).appendTo("body");
    }

    function randomOpacity() {
        var opac = 0;
        opac = Math.random() < 1;
        console.log(opac);
    }

    randomize();
});?
