You want to add a background color to a few specific sidebars in your blog – but not all of them. Headway makes this easy with a Live CSS editor that allows you to instantly see changes as you’re writing CSS code which in this case, is very simple:

body.custom#leaf-[leaf ID] {background: #HexNumber;}

The title says it all:

1. Select “leaf” element.
2. Change background color to “none”
3. Click save
4. Smile

Note: This will also work with footers and text headers.
