The Bottom Border Styling feature in Sticky Header Effects adds a clean, modern line beneath your header that appears as users scroll. This subtle yet impactful design element helps distinguish the header from the content below, improving visual structure and focus.

Whether you're designing a professional site, blog, or eCommerce layout, this feature adds polish without clutter. It’s responsive, lightweight, and seamlessly blends with your sticky header setup, offering a refined and user-friendly navigation experience across all devices.
