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">
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>
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">
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">
