How do I remove the dotted lines on a page?

I want to remove all the dotted lines, like under the category heading, on all pages. http://koras.mesitahousepublishing.com/category/koras-for-sale/

 

Hello,

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

Code:

.main-content .page-info {
border-bottom: none;
}

Thanks & Regards
