How to style content in jQuery Facebox

Question

I'm using jQuery Facebox plugin to create some modal windows. One situation is to display errors that might occur. If JS is disabled, I do this by displaying any errors in a normal div that is styled by CSS using a class selector. If the user does have JS enabled however, that div is hidden and the info is displayed in a facebox. The problem I have is that all the CSS styling is lost when the data is displayed within a facebox window. I understand that you can attach extra classes if you're calling facebox from a rel attribute in an anchor tag, but I'm using it programatically. Is there a way I can bind something to the facebox method?

Here's my js code (the HTML should be self-explanatory):

$(document).ready(function() {
    $(".errors").hide(); // hides the non-js error div
    $.errors = $(".errors").html(); // get the html from the error div
    if($.errors!==''){
        $.facebox($.errors); // if there are any errors, display them in facebox
    }
});
