Pinboard change black lines to white

[Moderated – please see the post below]

#header {
    border-top: #111 3px solid;
}

and change #333 for the footer

#copyright {
    ... some codes go here...

    border-top: #333 1px solid;

    ... some codes go here ...
}

Do not make changes to the theme files – you should use the Custom CSS option in your theme for changes so that they are not overwritten when the theme is updated. Custom CSS is under
Appearance > Theme Options > Layout

Okay so i made the changes works perfect.

I had to change the #footer as well to get rid of the border. Seems the only problem I have is getting the correct css.

Thanks for the help
