Plus Sign Icon - Clean Blue Cross Symbol for UI and Web Design #4381 (License: Personal Use)

This vector-style plus sign features a gradient blue fill with layered borders creating a subtle 3D effect, set against a clean white background. A solid black elliptical shadow grounds the symbol, giving it depth and making it suitable for interactive elements like add buttons or expand controls. The design balances simplicity with visual interest for modern web and app interfaces.

Used in user interfaces as an “add,” “expand,” or “positive action” button; commonly appears in dashboards, forms, mobile apps, and CMS tools where clear, scalable icons improve usability and accessibility.
