Range
Use our custom range inputs for consistent cross-browser styling and built-in customization.
Übersicht
Create custom <input type="range">
controls with .form-range
. The track (the background) and thumb (the value) are both styled to appear the same across browsers. As only Firefox supports “filling” their track from the left or right of the thumb as a means to visually indicate progress, we do not currently support it.
<label for="customRange1" class="form-label">Example range</label>
<input type="range" class="form-range" id="customRange1">
Disabled
Add the disabled
boolean attribute on an input to give it a grayed out appearance, remove pointer events, and prevent focusing.
<label for="disabledRange" class="form-label">Disabled range</label>
<input type="range" class="form-range" id="disabledRange" disabled>
Min and max
Range inputs have implicit values for min
and max
—0
and 100
, respectively. You may specify new values for those using the min
and max
attributes.
<label for="customRange2" class="form-label">Example range</label>
<input type="range" class="form-range" min="0" max="5" id="customRange2">
Steps
By default, range inputs “snap” to integer values. To change this, you can specify a step
value. In the example below, we double the number of steps by using step="0.5"
.
<label for="customRange3" class="form-label">Example range</label>
<input type="range" class="form-range" min="0" max="5" step="0.5" id="customRange3">
