Remove < from the formatting in the sidebar

How can I remove the default < from showing up in the side bar. I do not want any type of character or image showing there.

Thank You.

 

Hello,

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

Code:

.sidebar ul li{
background:none;
}
.sidebar ul li:hover{
background:none;
}

 

This worked perfectly. Thank You.
