theme: Gestures
Interactions like swipes, taps, and device motion.
1.3.4 Orientation
Rotating a device from portrait to landscape doesn’t stop everything being perfectly readable and usable.
1.4.10 Reflow
Content must remain readable and usable without requiring horizontal scrolling when viewed at a width of 320 CSS pixels (typically the width of a mobile viewport). Layouts should adapt responsively, and text should reflow to fit the screen.
1.4.13 Content on Hover or Focus
Tooltips and similar content should stay visible, be easy to dismiss (usually with the Esc key), and let users select and interact with the text.
2.5.1 Pointer Gestures
All actions that are carried out using a gesture (swiping, pinching, and so on) or drawing, can also be done with a button or buttons.
2.5.2 Pointer Cancellation
Actions (like pressing a button) aren’t triggered on mouse-down; rather on mouse-up.
2.5.4 Motion Actuation
There is no reliance on device motion, like shaking or tilting, to carry out an action.
2.5.5 Target Size (Enhanced)
Anything clickable must be at least 44 by 44 pixels, except links within a sentence which are okay to be the size of the text they encompass.
2.5.6 Concurrent Input Mechanisms
The user can happily switch between using a mouse, touchscreen, keyboard, or any other input device.
2.5.7 Dragging Movements
Any action requiring dragging, such as reordering items, must also be possible using buttons or other non-drag methods.
2.5.8 Target Size (Minimum)
Clickable elements must be at least 24 by 24 pixels, except for inline links.
