Usage

A label must appear preceding every slider. Values depicted in the label do not update as the slider is manipulated, to remain consistent with all other component labels.

Sliders default to a horizontal orientation to leverage the landscape orientation of most screens.

The current value is persistent and updates as the user interacts with a handle:

For a standard slider with a single handle, the current value updates at the right end of the slider.
For a double handle slider that defines a range, the current lower value updates at the left end of the slider and the current upper value updates at the right end.

The current value is also displayed as a tooltip above a handle while it's being manipulated.

When the slider has two handles, they are unable to pass one another or move close enough to equal the same value.

The default step value = 1 for a slider. This causes its handle to move smoothly along the linear scale by stepping one value at a time.

To create a slider with handle(s) that snap to preset values (e.g. 10, 20, 30, etc.), increase the slider's step value.

‍

Vertical Orientation

Sliders may also be vertically oriented:

The lower value of the range is on the bottom and the upper value is on the top.
The tooltip appears to the left of a handle if there's room, otherwise to the right.

‍

Keyboard Interaction

Right Arrow: Increase the value of the slider by one step.
Up Arrow: Increase the value of the slider by one step.
Left Arrow: Decrease the value of the slider by one step.
Down Arrow: Decrease the value of the slider by one step.
Home: Set the slider to the first allowed value in its range.
End: Set the slider to the last allowed value in its range.
Page Up (Optional): Increment the slider by an amount larger than the step change made by Up Arrow.
Page Down (Optional): Decrement the slider by an amount larger than the step change made by Down Arrow.

Common Button Labels and Usage

Title case, 2-3 words maximum.
Do not combine actions in a label (exception: "Customize & Buy").
If standard labels don't fit the button's purpose, align label with the task the user is attempting.
