_ducksinarow, yesterday. It will show you how to achieve a flat look for a layout with square components [tutorial].In your user layer [or your theme layer if you don't use the general customizations interface at all], you'll need to place the following code snippet:
===
set header_bgcolor = "#hexcode";===
Replace hexcode with an actual hex code.
Then, in your stylesheet [tutorial], place the following CSS:
===
.dkLine {
background-color: #hexcode;
}
.ltLine {
background-color: $*header_bgcolor;
}
.medLine {
background-color: $*header_bgcolor;
}
.divLine {
background-color: $*header_bgcolor;
}
.tabBg {
background-color: $*header_bgcolor;
}===
.dkline is the color of the component border. Be sure to replace hexcode with an actual hex code.
The rest of the properties are all inside the header, as well as in your links list, page summary, and navigational component.
