guideline: Input Modalities
Support input methods beyond a keyboard and mouse.
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.
2.5.3 Label in Name
The visible text of a form field, button, or link matches the text in the underlying code.
2.5.4 Motion Actuation
There is no reliance on device motion, like shaking or tilting, to carry out an action.

Anything clickable should 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.
