[Theme: Neurocity] Remove Menu Bar

Hi there:

I am trying to remove the shadow box Menu that displays in the header of my page https://www.ladywithelectrichair.com

I believe the element I am trying to remove is the following coding in the header.php:

`<div class=”mythemes-topper”>
<a class=”mythemes-nav-btn btn-collapse” href=”javascript:void(null);” data-effect=”mythemes-effect-1″>
<span class=”mythemes-btn-items”>
<span class=”mythemes-btn-item”></span>
<span class=”mythemes-btn-item”></span>
<span class=”mythemes-btn-item”></span>
</span>`

So in my very limited knowledge of HTML & CSS I entered the following code into my stylesheet:

`.mythemes-topper{
display: none;
}`

But that did not work. Any suggestions?
