How to add text inside ionic range slider and ionic toggle?

I will be very happy if someone shows me the way ho to do this:

  1. Add one letter inside ionic range slider.
  2. Add short text inside ionic toggle.

I am not able to find solution. Anybody help me, please?

I have a strange solution :slight_smile: for the range slider.

I am currently developing an app related to electricity. So I need the range slider for setting voltage.


      <div class="item range range-positive">
        <input ng-model="ac.powerValueUMax" type="range" min="0" max="5" class="rangeU">



content: "U";
position: absolute;
top: -26px;
left: -21px;
padding: 30px;
color: black;


Why is it strange solution? Because it is not universal.

Any ideas how to solve it universally?
