Version 5.1.1


Sliders allow users to quickly select a value within a range. They should be used when the upper and lower bounds to the range are invariable.


Diagram of a Slider's anatomy, including label, track, handle, fill, and value.


Example of a Slider with a label.


Sliders should always have a label. In rare cases where context is sufficient and an accessibility expert has reviewed the design, the label could be undefined. These sliders should still include an aria-label in HTML (depending on the context, “aria-label” or “aria-labelledby”).

Examples showing both top and side label variants of Slider.

Label position#

Labels can be placed either on top or on the side. Top labels are the default and are recommended because they work better with long copy, localization, and responsive layouts. Side labels are most useful when vertical space is limited.

Example of Sider values with appended unit text.

Value and value unit#

The value is the number selected within the range of the slider. This can have a value unit appended to show the unit of measurement, such as "%" or "px".

Examples of Sliders with varying widths.


The width of a slider can be customized appropriately for its context.

Example of a Slider with a filled track.


The track of the slider can have a fill. By default, the fill originates from the left side of the track.

Example of a Slider with the start point of the fill offset.

Fill start#

If the value represents an offset, the fill start can be set to represent the point of origin. This allows the slider fill to start from inside the track.

Example of a Slider with a gradient track fill.


A gradient can be added to the track of any slider to give more meaning to the range of values. Tracks with a gradient can also have a fill. A gradient track should not be used for choosing a precise color; use a color slider, color area, or color wheel instead.

Example of a Slider with an input field for setting precise values.


In situations where users should be able to precisely input a value, the value can be editable within a text field.

Example of a disabled Slider.


A slider in a disabled state shows that an input exists, but is not available in that circumstance. This can be used to maintain layout continuity and communicate that a slider may become available later.

Table of options#

From the design point of view, each component has a number of options. These options and their names are platform agnostic, and each implementation should adapt these to fit into their framework.

Keyboard focus#

A slider can be navigated using a keyboard. The keyboard focus state takes the slider’s visual hover state and adds a blue ring to the slider handle in focus.

Examples of Sliders with placement of the value following placement of the label.

Value placement#

The value follows the placement of the label: on top when the label is on top, and on the side when the label is on the side. There is an exception to this rule when the value is editable, shown within a text field (standard or quiet style); in this case, the editable input is always placed on the side. This editable input should be labelled using "aria-labelledby" or "aria-label" as well.

Example of a Slider with overflowing label text.

Text overflow#

When the label is too long for the available horizontal space, it wraps to form another line.

Key example of sliders in Windows “high contrast black” theme with label “Slider” and disabled slider with label “Disabled slider” both with value of 0.

Windows high contrast mode#

In Windows high contrast mode, sliders should be displayed using the high contrast theme-specified colors for buttons. By default, track and handle border colors should be the same as the button text color and labels should use default text color. In hover and keyboard focus states, the track and handle border colors should display as the button border color. In the disabled state, border and text color should display as the disabled color.

Usage guidelines#

Include a label#

Every slider should have a label. A slider without a label is ambiguous and not accessible.

Example of a correct Slider that includes a label.
Example of an incorrect Slider which has no label.

Review label-less designs#

In rare cases where context is sufficient and a label could be absent, make sure to have the design reviewed and approved by an accessibility expert. These should still include an aria-label in HTML (depending on the context, “aria-label” or “aria-labelledby”).

Example of a Slider without a label that passed inclusivity review as an exception.

Allow a hot text option when needed#

In addition to dragging the handle, sliders can provide more ways to change the value (known as “hot text”) either by clicking on the value text and dragging up/down, or by scrolling up/down while hovering over the value text.

Example of a Slider with hot text enabled.

Show value units to help provide context#

Slider values can be shown with a unit when it helps provide context (e.g., “%” or “px”). When the value is shown within a text field, the unit disappears on focus.

Example of a Slider with units included for context.
Example of a confusing Slider that does not include units for context.

Prefix positive/negative values#

If the value ranges from negative to positive, prefix the value with a plus (+) or minus (-) sign. When the sign is shown within a text field, it remains visible on focus. When the sign is shown outside the text field, there should be a space between the sign and the numerical value for readability.

Examples of Sliders with correct implementation of positive and negative prefixes.
Example of poorly implemented Sliders that are missing positive and negative prefixes.


Example of Sliders in RTL configuration with mirrored layout.


For RTL (right-to-left) languages, the layout of the slider is mirrored. The label is right-aligned, the value is left-aligned, and the fill progresses from right to left. Keep in mind that the placement of the percent sign differs depending on the locale.
