CSS 31 💻 any-hover and any-pointer media features - KandZ

These two media features let you detect the input capabilities of a user’s device — whether they have a mouse that can hover, a touch screen, or both. This is crucial for creating interfaces that work well across all device types.

Overview of Features

Feature	Description	Values
`any-hover`	Detects if any pointing device can hover	`none`, `hover`
`any-pointer`	Detects the accuracy of any pointing device	`none`, `coarse`, `fine`

1. any-hover

The any-hover media feature detects whether any available pointing device can hover over elements.

@media (any-hover: none) {
    .container {
        background-color: lightcoral;
    }
}

Values

Value	Description
`none`	No pointing device can hover
`hover`	At least one pointing device can hover

Key Points:

Desktop browsers with a mouse → any-hover: hover
Mobile browsers with touch input → any-hover: none
Devices with both mouse and touch → any-hover: hover (because the mouse can hover)

2. any-pointer

The any-pointer media feature detects the accuracy of any available pointing device.

@media (any-pointer: none) {
    .container {
        background-color: lightcoral;
    }
}

Values

Value	Description
`none`	No pointing device available
`coarse`	Pointing device with limited accuracy (e.g., touch, stylus)
`fine`	Pointing device with fine accuracy (e.g., mouse, trackpad)

Key Points:

Desktop with mouse → any-pointer: fine
Mobile with touch → any-pointer: coarse
Devices with both → any-pointer: fine (because at least one device is fine)

any-hover vs hover

Feature	Description
`hover`	Detects the primary pointing device’s hover capability
`any-hover`	Detects if any pointing device can hover

Example:

A laptop with a touchscreen and a mouse:
hover: hover (primary device is mouse)
any-hover: hover (at least one device can hover)
A tablet with a Bluetooth mouse:
hover: none (primary device is touch)
any-hover: hover (mouse can hover)

any-pointer vs pointer

Feature	Description
`pointer`	Detects the primary pointing device’s accuracy
`any-pointer`	Detects the best accuracy among all pointing devices

Example:

A laptop with a touchscreen and a mouse:
pointer: fine (primary device is mouse)
any-pointer: fine (at least one device is fine)
A tablet with a Bluetooth mouse:
pointer: coarse (primary device is touch)
any-pointer: fine (mouse is fine)

Tablet with Bluetooth mouse	`none`	`hover`	`coarse`	`fine`

Best Practices

✅ Do This:

/* Hide hover-only elements on touch devices */
@media (any-hover: none) {
    .hover-only {
        display: none;
    }
}

/* Provide tap-friendly alternatives */
@media (any-hover: hover) {
    .tooltip:hover .tooltip-text {
        display: block;
    }
}

/* Detect fine pointers for precision UI */
@media (any-pointer: fine) {
    .color-picker {
        display: block;
    }
}

@media (any-pointer: coarse) {
    .color-picker {
        display: none; /* Hide precision UI on touch */
    }
}

❌ Don’t Do This:

/* Don't rely on hover for critical functionality */
.delete-btn {
    display: none; /* Only visible on hover — bad for touch! */
}
.item:hover .delete-btn {
    display: block;
}

/* Don't confuse hover with any-hover */
@media (hover: none) {
    /* Only checks primary device — may miss secondary devices */
}

/* Don't assume all desktops have a mouse */
@media (min-width: 1024px) {
    .hover-effect { /* May fail on touchscreen laptops */ }
}

Pro Tip: Use any-hover and any-pointer to create input-aware interfaces. The key insight is that hover/pointer check the primary input device, while any-hover/any-pointer check all available devices. For example, a tablet with a Bluetooth mouse has hover: none (primary is touch) but any-hover: hover (mouse can hover). Use any-hover to detect if hover effects are possible at all, and any-pointer to detect if precise input is available. Always provide tap-friendly alternatives for touch devices!
