Operable 2.5 Input Modalities

Make it easier for users to operate functionality through various inputs beyond a keyboard.

Examples

A slider that can be operated by dragging the thumb can also be operated with a keyboard via buttons or inputs.
A list that can be reordered by dragging and dropping also has button controls.

Depending on which level of compliance your website needs, the following criteria needs to be met.
Criterion	Level	Description
2.5.1	A	Content can be controlled with a range of input types.
2.5.2	A	Prevent accidental pointer input by either not executing functions on down-events, by only completing functions on up-events, or by making sure the action of up-events will reverse the action of the corresponding down-events.
2.5.3	A	Visible text labels and programmatic names of the same control should match.
2.5.4	A	Any function that can be operated by device motion also has a corresponding component control.
2.5.5	AAA	All targets for pointer inputs should be at least 44px by 44px.
2.5.6	AAA	The content on the website does not restrict the type of input modalities that can be used (such as touch screen only interactions).
