Sidebar too wide

I thought the sidebar (right) was too wide, so I added this custom css to the “Customize” => “Custom Css” It works – so I figured I’d share – it was a question here – but the comments are closed on that question.

.sidebar-right .sidebar-area.col-md-4{
width: 25%;
margin-top: 10px;
}

.sidebar-right .content-area.col-md-8 {
width: 75%;
}

The page I need help with: [log in to see the link]
