What does a line beginning with a dot mean?
<p>I was reading through the <a href="http://craftyjs.com/tutorial/bananabomber/create-a-game" rel="nofollow">Crafty tutorial</a> and came across a code snippet that I can't find documentation for. It is so hard to search for punctuation.</p>

<p>The lines in question, 11 and 12, follow the <code>Crafty.e</code> line and begin with <code>.text</code> and <code>.css</code>. What object do those properties belong to?</p>

<pre><code>//the loading screen that will display while our assets load
Crafty.scene("loading", function () {
    //load takes an array of assets and a callback when complete
    Crafty.load(["sprite.png"], function () {
        Crafty.scene("main"); //when everything is loaded, run the main scene
    });

    //black background with some loading text
    Crafty.background("#000");
    Crafty.e("2D, DOM, Text").attr({ w: 100, h: 20, x: 150, y: 120 })
            .text("Loading")
            .css({ "text-align": "center" });
});

//automatically play the loading scene
Crafty.scene("loading");
</code></pre>

<p>Where would this be in the specification?</p>
