## What it is
A pointer target is the area that reacts to a click or tap. WCAG 2.2 success criterion 2.5.8 Target Size (Minimum), level AA, requires that target to be at least 24 by 24 CSS pixels, with listed exceptions: *spacing* (an undersized target is acceptable if a 24-pixel circle centred on it does not intersect another target or another such circle), *equivalent* (the same function is available through a target on the page that does meet the size), *inline* (targets inside sentences or constrained by the line height of surrounding text), *user agent control* (default-rendered controls not styled by the author) and *essential*. The older 2.5.5 Target Size (Enhanced), level AAA, asks for 44 by 44 CSS pixels with a similar exception list.

CSS can tell what is pointing. The `pointer` media feature reports the primary input's accuracy: `none`, `coarse` (limited accuracy, such as a finger on a touchscreen) or `fine` (an accurate device such as a mouse); `any-pointer` covers all available inputs. The companion `hover` feature reports whether the primary input can conveniently hover.

## Why it matters
Fingers are wide and imprecise, tremor and low vision make small targets hard, and dense toolbars are where mis-taps happen. Hover-only affordances (menus that open on mouseover, tooltips holding required information) are unreachable on a touch screen.

## How to apply
- Give interactive controls a minimum box of 24 by 24 CSS pixels through `min-width`/`min-height` or padding, and aim higher for primary actions; icon-only buttons are the usual offenders.
- Where targets sit in a row (pagination, toolbar icons), either enlarge them or space them so the 24-pixel circles do not overlap, using `gap` rather than margin on the last item.
- Under `@media (pointer: coarse)` increase padding on controls, checkboxes and list rows, and widen sliders' thumbs; under `(pointer: fine)` a denser layout is acceptable.
- Never rely on hover alone: anything shown on hover must also appear on focus and on tap, and `@media (hover: none)` can switch a hover menu to a click-to-open one.
- Make the whole row or card the target when it is the obvious tap area, without letting nested controls overlap it.

## Pitfalls
CSS pixels are not device pixels; the 24-pixel minimum is independent of screen density. The inline exception covers targets inside a sentence or constrained by the line height of surrounding text, not icons in a toolbar or list. Enlarging the clickable area with transparent padding changes layout; a `::before` pseudo-element with negative insets enlarges the hit area without moving neighbours. Devices with both touch and mouse report the primary pointer only; check `any-pointer` if either matters.
