# Pure CSS Tooltip Generator With Arrow

> Generate a tooltip from a data attribute — no JavaScript, no extra markup.

A CSS tooltip is a pseudo-element reading its text from a data attribute, so the markup stays one element and there is no JavaScript to load or position. It appears on hover and on :focus-visible, which is what makes it reachable by keyboard rather than mouse-only. The arrow is a second pseudo-element built from a transparent border — a border-only box with three sides transparent renders as a triangle, which is why no image is needed.

## FAQ

### Is a CSS tooltip accessible?

Partly. Including :focus-visible makes it reachable by keyboard, which a hover-only tooltip is not. But a pseudo-element is not announced by every screen reader, so anything essential should also be in an aria-label or visible text — treat this as a visual affordance, not the only copy of the information.

### How does the arrow work with no image?

A zero-size box with a thick border renders its four border sides as triangles meeting at the middle. Make three of them transparent and the fourth is a single triangle pointing away from the visible side.

### Why does my tooltip get cut off?

An ancestor with overflow: hidden clips it, because the tooltip is a child of the trigger. Either remove that overflow on the ancestor or use the Popover API, which escapes the clip by rendering in the top layer.
