I downloaded the rounded corner presets zip (three times) and when it was extracted, it contains only two of the three files that it is supposed to contain.
rounded corner preset 2_column
rounded corner preset 3_column.
The instructions on page 2 of Working with rounded corner layouts in CSS Sculpture call for a file called:
2 Column Fixed, Rounded Corner, Left Sidebar, Header and Footer png
Apart from this being an odd name for a file, it does not exist in the download, so where do I find it? Or am I missing something.
The article is long on instruction and short on explaining what we are supposed to be trying to achieve. I think that it would benefit from a rework.
