Hover detail overlay timing
hover-detail-overlay-timing
Hover detail overlay timing — 0.5 s delay on mouseover; close immediately on mouse-out.
Description
Hover detail overlays should appear after a 0.5 second mouseover delay and close immediately on mouse-out. Instant open causes flicker as the pointer crosses the target; delayed close leaves stale overlays hanging over content. The half-second delay filters accidental passes while still feeling responsive for intentional hover. Apply this timing to hover detail layers; click-triggered popovers follow different open and close rules.
When to use
Hover detail overlays that enrich content without leaving the page.
Not when
Click-driven popovers or menus that are not hover detail overlays.
Agent hint
Delay overlay open 0.5 s on hover; close immediately when the pointer leaves.
Detail overlay appears after 0.5 s hover; closes immediately on mouse-out.
Instant open, delayed close, or no 0.5 s delay.
