I’m new to using sticky’s so I have no clue how to due this. I found some examples at http://stickyjs.com and have them working as is, but I can’t figure out how to customize it to work on my site.
here is a link to a site that is doing what I’m trying to do:
http://www.thumbtack.com
Here is a link to the page I’m trying to get it to work on:
http://aaronhaas.com/bsi2/index.html
If you looking at the site I’m trying to have the blue sticky start out invisible and appear after the user scrolls down past the banner at the top and then stick just below the nav bar.
i want it to look like this after the user scrolls
I have this in my head tags:
<script type="text/javascript" src="js/jquery.sticky.js"></script>
<script>
$(window).load(function(){
$("#cta-sticky").sticky({ topSpacing: 100 });
});
</script>
here is the sticky div:
<!-- sticky-->
<div id="cta-sticky">
<form class="form-inline center" role="form">
<h4 class="cta-title">This is the sticky</h4>
<div class="form-group">
<label class="sr-only" for="">Zip Code</label>
<input type="text" class="form-control" id="zip" placeholder="Zip Code">
</div>
<button type="submit" class="btn btn-orange">Get Quote</button>
</form>
</div>
here is the query sticky file:

any help would be greatly appreciated
