HTMLMeterElement: low property

The low property of the HTMLMeterElement interface represents the low boundary of the <meter> element as a floating-point number. It reflects the element's low attribute, or the value of min if not defined. The value of low is clamped by the min and max values.

This property can also be set directly, for example to set a default value based on some condition.

<label for="fuel">Current fuel level:</label>
<meter
  id="fuel"
  min="0"
  max="100"
  low="15"
  high="66"
  optimum="80"
  value="50"></meter>

const meterElement = document.getElementById("fuel");
console.log(meterElement.low); // 15
--meterElement.low;
console.log(meterElement.low); // 14
