Remove all borders in Thesis 1.5

Re-working the Thesis framework to your own liking?

Well, if your doing a huge overhaul, you might want to get rid of the separator lines the default styling has included. This includes the sidebar lines, the teaser box lines, the comment lines.etc.

To get rid of these lines, while editing the css (you should be using the custom.css located in the custom folder of Thesis) input this code at the top:

.custom #header, .custom .post, .custom .teasers_box, .custom #footer, .custom #footer a, .custom #footer a:active, .custom #archive_info, .custom .prev_next, .custom #comment_list, .custom #comment_list dd, .custom #commentform, .custom #sidebar_1, .custom #sidebar_2, .custom #comment_list dt.comment, .custom #comment_list dd.comment, .custom #comment_list dl .bypostauthor .format_text, .custom #trackback_list {
        border-bottom: 0px;
        border-top: 0px;
        border-right: 0px;
        border-left: 0px;
}
.custom #content_box, .custom #column_wrap {
        background: none;
}

This will effectively get rid of all separators, no matter the framework (page or full-width) or column amount / justification. Also, since you placed this code at the very top of the document, any border you might want to add in later will over-rule the top declarations. Good luck!
