I added a header and footer by clicking the "Add HTML/CSS Insert" tab for the Atahualpa theme and I see a code in my source code near the top that looks like this:
{margin-top:10px;margin-bottom:10px;padding-top:0;padding-bottom:0}
This causes padding in the table I created for the header and footer which makes the table larger. Does anyone know how to remove or delete this code?
