Hello, Yes, I know it''s off-topic and nuby question, but I really don''t know anything about graphic, I''m all a coder who lives in his text editor, so sorry at first! I need to create round corner box for my web app, I know how to form a box using CSS, I just dunno how to create those rounded corners. Is there an easy to use tool for creating them, out there? Thank you
