aria-valuemax

The aria-valuemax attribute defines the maximum allowed value for a range widget.

The aria-valuemax attribute defines the maximum value allowed for range widgets. It is similar to the max attribute of <progress>, <meter>, and <input> of type range, number and all the date-time types.

When creating a range type role, including meter, scrollbar, slider, and spinbutton on a non-semantic element, the aria-valuemax enables defining a maximum that is more than the minimum value and is a required attribute of slider, scrollbar and spinbutton.

Declaring the minimum and maximum values allows assistive technologies to convey the size of the range to users. The minimum value is defined with aria-valuemin.

The code below shows a simple slider with a maximum value of 9.

<div id="dimesLabel">Dimes</div>
<div role="slider" aria-valuenow="0" aria-valuemin="0" aria-valuemax="9" aria-labelledby="dimesLabel" id="dimes"></div>

<number>

An integer or decimal number that is greater than the minimum value.
