The CSS panel mentioned in the Settings section can be used to style outline text by level. For example:
.concord-level-1-text {
font-family: Arial !important;
font-weight: bold !important;
}
.concord-level-1 {
margin-bottom: 8px !important;
}
Will make the top level heads bold and in Arial font and will add 8 pixels after every level.
Another example, if you wanted to provide a background image to "skin" the Fargo app, you would add this bit to the CSS text.
body {
background-image:url('https://dl.dropbox.com/u/36518280/images/niagara.jpg');
}
