Question

I am trying how to make form step wizard work using Hyperscript: https://hyperscript.org/ Can anyone point me in the right direction?

This is my code:

<div class="step" step-index="1">
    
    <h1>Step 1</h1>
    
    <button>Next</button>

</div>

<div class="step" step-index="2">
    
    <h1>Step 2</h1>
    
    <button>Prev</button>
    <button>Next</button>

</div>

<div class="step" step-index="3">
    
    <h1>Step 3</h1>
    
    <button>Prev</button>
    <button>Submit</button>

</div>
