I am trying to format the range slider so the result appear duplicated. For eg. it returned 16 by default. I want under the slider to see 16x16, 32x32...Both numbers must move togheter.

Heres what i tried:

 <input type="range" min="2" max="50" value="16" class="size"
 oninput="this.nextElementSibling.value = this.value">
  <output>16</output

Is there a way to format the output? Thank you
