How do I fix the sidebar so the content doesn't spill out of the content area?

When I use the text widget or java script adder widget, the text spills outside the viewing area. Please see attached image. A link to the page demonstrating this issue is as follows:

If you could provide me with a solution, I would be most appreciative.

Thank you in advance.

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.sidebar {
width: 70%;
}

Adjust its value as per your requirement.

 

Thanks Gourav. That worked perfectly.

Cheers
Laurie
