Adjusting the Width of the Sidebar

I am trying to run advertisements on my site and when I inserted an ad size of 300x250, the right sidebar is not wide enough to accommodate the ad and it hangs off the edge. I have looked through the Stylesheet and can't figure how to increase the width.

My site: www.MyEyeshadowConsultant.com

Can you please assist?
Thank you for your time.

 

Paste the following code in your custom css
Appearance -> Theme Options -> Styling Options -> Custom CSS

Code:

.content_wrapper .sidebar_wrapper .sidebar {
padding-left: 0px;
width: 320px;
}
.sidebar .wrap_sidebar {
width: 310px;
}
html > body div.bsap_1283437 a.adhere {
width: 307px;
}

This will solve your issue.

 

That worked like a charm; thank you, Piyush!
