Please see below. And thank you for your response. Please advise, what line on the style sheet are you looking at?

However if you want to hide that box from the css, in the column-left section, add the following code to the bottom:

display: none;

So, it will look like:

#column-left {
background: white;
position: absolute;
width: 130px;
left: -166px;
top: 0;
padding: 10px;
display: none;
