Widget for collecting leads

I have JavaScript widget code for collecting leads:



`// Create an immediately invoked functional expression to wrap our code
(function() {

// Define our constructor
this.Widget = function(options) {

this.widgetWrap = null;
this.widgetClose = null;
this.widgetHeaderTitle = null;
this.widgetInput = null;
this.widgetFormInputError = null;
this.widgetFormSubmit = null;
this.titleAnimationInterval = null;
this.overlay = null;
this.formWrap = null;
this.formIframe = null;

this.images = {

Using CSS to setup your styles, and just giving items classes would cut this whole thing down to maybe a couple dozen lines. You can even do all your animation with CSS, thereby letting the browser just do what it's there to do.

Actually, on a further look to see what this is actually doing -- Unless there's some purpose here that I'm completely missing, and you haven't explained -- there's only about 4 or 5 total lines of code here, the rest is all just simulating things you can do purely in CSS/HTML.

You should absolutely re-think how you're approaching this from square 1. A few lines of HTML, a couple dozen lines of CSS, and 4 or 5 lines of Javascript would do this.
