Create custom <input type="range"> controls with .form-range.
Add the disabled boolean attribute on an input to give it a grayed out appearance and remove pointer events.
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.
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".
