Template repeated dotted line problem

Hi,

I have encountered a strange problem with the world news template when Joomla is setup to display articles in Catagory/Blog format. The problem is with repeat dotted lines that appear at the bottom of the page - seemingly one for each article - as shown in the attached screenshot.

Please can you give any suggestions on which part of code to edit/modify to fix this issue?

Thanks

I managed to fix this, incase anyone else has this issue - the line to comment out is in the 'Joomla.css' file:

/* border-bottom: 1px #c8c8c8 dotted; */
