- /**
- * @name Range
- * @description
- * The Range slider lets users select from a range of values by moving
- * the slider knob. It can accept dual knobs, but by default one knob
- * controls the value of the range.
- *
- * ### Range Labels
- * Labels can be placed on either side of the range by adding the
- * `range-left` or `range-right` property to the element. The element
- * doesn't have to be an `ion-label`, it can be added to any element
- * to place it to the left or right of the range. See [usage](#usage)
- * below for examples.
- *
- *
- * ### Minimum and Maximum Values
- * Minimum and maximum values can be passed to the range through the `min`
- * and `max` properties, respectively. By default, the range sets the `min`
- * to `0` and the `max` to `100`.
- *
- *
- * ### Steps and Snaps
- * The `step` property specifies the value granularity of the range's value.
- * It can be useful to set the `step` when the value isn't in increments of `1`.
- * Setting the `step` property will show tick marks on the range for each step.
- * The `snaps` property can be set to automatically move the knob to the nearest
- * tick mark based on the step property value.
- *
- *
- * ### Dual Knobs
- * Setting the `dualKnobs` property to `true` on the range component will
- * enable two knobs on the range. If the range has two knobs, the value will
- * be an object containing two properties: `lower` and `upper`.
- *
- *
- * @usage
- * ```html
