[SOLVED] code from center column style appears on the site

Hi, I try to help a friend who has a strange problem appearing on his website. Don't know exactly what he has been doing, said he only edited the code in ATO Center Column style with border-right: solid 5px #a1a1a1; - he also coded border-top and border-bottom. Now I logged on his WP panel and try to fix it, I delete the code in Center Column style, save but it is still there.
