The Hover Tunnel Simulator

Move your mouse down from the trigger box across the buffer zone into the menu. Toggle modes to experience why non-buffered menus abruptly collapse.

Properties [Hover Trigger]
✓ CONTIGUOUS HIT BRIDGE (padding-top: 14px)
Mega Dropdown Panel
Inside the dropdown. Active state remains locked so long as mouse cursor stays within the bounds or hits the contiguous bridge.

Hit-Test Telemetry HUD

Cursor Coordinates: X: 0, Y: 0
Active Hover Target: none
Menu Visibility State: CLOSED
Bridge Buffer Status: ACTIVE (Contiguous)
Dead-Zone Drop Count: 0 drops
Pro Tip: Using padding-top on the absolute wrapper rather than margin-top creates an unbroken hit-test polygon. The cursor never leaves the :hover boundary.
