Popover

Overview

Show lightweight contextual controls. It raises contextual work above the current page and returns focus to the invoking control.

When to use

Use HE/Popover when you need to show lightweight contextual controls. Keep its role distinct from transport freshness, animal-health severity and model confidence.

Example

<div class="he-popover" style="position:relative;display:block">Evidence captured at 14:32:09 from RGB channel 2.</div>

Anatomy

Anatomy stays identical in Pasture and Atlantic. A responsive layout may wrap or stack parts, but reading order and focus order remain equivalent.

Variants and states

Accessibility

Move focus only for interactive content and close on Escape and outside interaction.

• Maintain a visible keyboard focus indicator and a logical focus sequence.
