Intent to Prototype: highlightsFromPoint API

Spec is in progress and being written.

The highlightsFromPoint API enables developers to interact with custom highlights by detecting which highlights exist at a specific point within a document. This interactivity is valuable for complex web features where multiple highlights may overlap or exist within shadow DOM. By providing precise point-based highlight detection, the API empowers developers to manage dynamic interactions with custom highlights more effectively, such as responding to user clicks or hover events on highlighted regions to trigger custom tooltips, context menus, or other interactive features.

Highlights visually differentiate specific ranges within a document, such as comments, search results, or spelling errors. As web features grow more complex, managing custom highlights becomes increasingly challenging, particularly when dealing with overlapping highlights or content within the shadow DOM. Developers need a way to interact with individual highlights at precise points within the document, enabling more efficient control of dynamic and interactive content with custom highlights. This allows for features like displaying custom tooltips, context menus, or other interactive elements based on accurate point-based highlight detection.

Pending

The 'highlightsFromPoint' API is a new feature so there isn’t a compatibility risk. The interoperability risk is limited to the usual risk of limited adoption and/or inconsistent browser support for a new feature.
