How can I delete the boder line of block

Dear all, I insepet the webpage but have no idea how can I delete the border line of block, it is ugly.


You need to determine which element does that and how it is done. There is more than one way todo such thing in HTML/CSS.

The best way is examine the code and use Ctrl+Shift+C and hover on the line. It will show what element you are hovering on in both the page and the source.
